Thanks for the spreadsheet. But I can't search in the schematic you sent either. PRINT is not the way to go for a searchable PDF. You need to PLOT. It does not seem to make any difference other than the text. 73, Burns Fisher, WB1FJ *AMSAT(R) Engineering -- Flight Software* On Wed, Jan 31, 2024 at 2:25 PM Bob Stricklin via pacsat-dev < pacsat-dev(a)amsat.org> wrote: > Burns, > > I believe the copy on GitHub was printed but here is one I just made which > for sure is printed. > Note this is Rev D and includes some changes but most of these are not > related to software. > > I am also attaching the spread sheet I did in the past and updated > recently which is a list of pin assignments from the CPU.

Burns, I believe the copy on GitHub was printed but here is one I just made which for sure is printed. Note this is Rev D and includes some changes but most of these are not related to software. I am also attaching the spread sheet I did in the past and updated recently which is a list of pin assignments from the CPU. This is easier to work with for a software reference.

Schematic of Blinky

Hi Bob, I'm just getting started on software for the Blinky, but to do that, I need to find things on the schematic. I found the schematic on gihub (Schematic_231004.pdf) but it is not searchable, so I really can't find (easily) where traces connect. For example, I found "UART_TX1 (as well as RX1,2 and Tx2) but can't easily see what they connect to. Is there a header somewhere (I could not see that on the physical board). If you can tell me where the UART lines go reasonbly soon, that would help, but in the slightly longer term if you can make a KiCad PDF schematic with the "plot" command rather than the "print" command (the ONLY thing that I know about Kicad, I might add), that will produce a PDF with actual text in it such that it can be searched.

Flight software description
by Burns Fisher (AMSAT) 30 Jan '24

30 Jan '24

I have told about a zillion people about a zillion times that there are reasonably detailed description of the flight software in a Wiki in our Redmine repository. What is Redmine you ask? Well, you see the problem. It was created for problem and document tracking at the start of the Golf project, but no one paid attention or used it except for Zack and me. So I have not even bothered to create accounts for new people. In any case, more people are asking about the flight software. The description, while really written for Golf, is essentially true for Golf, Pacsat, and Fox, Thus I decided to put it in the Golf SVN (and I'll put it in the PacSat document git repo soon). It is in https://svn.amsat.org/golf/FlightSoftwareDescriptions. There are 4 pdf files there with different things of interest. And I just realized I have a duplicate and am missing one file, but I have to leave now,. The most important 3 are there: Multiple_CPUs_with_Code_Composer_Studio.pdf Software_Description.pdf Use_of_HalCoGen_with_Golf_and_PacSat_Flight_Software.pdf These are PDFs. The source is in Redmine. 73, Burns Fisher, WB1FJ *AMSAT(R) Engineering -- Flight Software*

Test data and Updated Box
by Bob Stricklin 28 Jan '24

28 Jan '24

All, I spent a time this weekend testing the boards and tweaking/changing the part values mostly in the 2M PreAmp and power divider section. I created a new folder in Github PacSatDoc for TestData and uploaded the photos and a video to this folder. Not sure how Github feels about this but I will see. We can delete things after people have a chance to take a look. The boiled down results are the PreAmp frontend has a range of 10 dB gain through the FET + Filter+ Power divider to 5 dB on the lowest. I checked all 8 of the balanced ports and found them to be mostly the same. I turned down the 140 MHz carrier until I could see it just about the noise on the spectrum analyze and the most sensitive channel was working at -94dB. Power supply info/photos was also uploaded. Over the next few days I hope the test the final amplifier. Uploaded a new set of STL files for the box. I looking at options to get these printed now. Tomorrow i will push the code I have up to my GitHub site. Bob

Paranoia is helpful until it's not. Congrats I realized the other three boards were not working due to my paranoia. The 5V regulator must have at least 10 mA of current draw and I had all the follow on circuits disconnected. When I put a load in place all working fine.

Working hard on the boards. Spent the weekend swamping out and adding parts to the 3 untouched boards. A few more parts need to be added. Have the power supply sections working. The chip for the 1.2 volt supply is the most difficult to work with. Goal is to ship these out to people soon. I wanted to get one out to Burns yesterday but taking longer to get them ready. Today is tied up with travel and doctors visits. I realize looking through the code that the bits on the IO lines are being changed individually. This means that getting HCG correct was just a piece of what we needed. Getting all the bits correct will take some time. Bob

Software problems on blinky
by Burns Fisher (AMSAT) 19 Jan '24

19 Jan '24

Hi Bob, I was not able to go to the meeting last night, but I hear you are still having problems with the software. I just spent several hours debugging/staring at/thinking about a subtle problem causing an OS crash on my own Golf software, so I guess my thought is that I'm not too likely to be able to suggest a quick fix for you without a lot of hands-on. That said, if you want to send me a copy of the board, (and I understand that it may have flaws), I'm more than willing to look into the s/w problem. I'm sometimes pretty good at finding simple hw problems too. Let me know what you think. 73, Burns Fisher, WB1FJ *AMSAT(R) Engineering -- Flight Software*

Re: Memory Problem on PacSatSW
by Bob Stricklin 16 Jan '24

This seems to fix the short term issue… I changed FreeRTOSConfig.h like this: //#define configTOTAL_HEAP_SIZE ( ( size_t ) 32768 ) //Default //#define configTOTAL_HEAP_SIZE ( ( size_t ) (2*65536 )) /*BF Changed*/ #define configTOTAL_HEAP_SIZE ( ( size_t ) (65536 + 20000)) /*N5BRG Changed 240116*/ With the code this way we are using 85% of available space. This will be fine for me to continue testing chips. I will get back to test the board. Thanks for help.

I have a few comments (all numbers are hex) * (this is true of Golf too--I never noticed) the psect named STACKS is unused.

That will tell you how much you can reduce that heap size by (but of course you want to leave some!) You can change the size in FreeRTOSConfig.h. Change "configTOTAL_HEAP_SIZE" Right now it is double what I had it at (it is 128K, was 64K) * I don't see a problem with flash or RAM memory. It says you have 10c112 bytes unused in flash and 932b unused in RAM. If we need to find some available memory, we can probably do it, but I don't see a problem here right now. Your "out of memory" must be a runtime message? Exactly what does that error look like? Is it in the file system (i.e. MRAM)? That is a totally different story. You might try "get mram size" to see if it matches the amount you think you have.

Do any of you know the proper steps for me to get this initial code into Github? Here is a image of what I have done. I thought it was going to post but a cannot get the commit button at bottom to take action. Bob

Re: Memory Problem on PacSatSW

Thanks. I have a few comments (all numbers are hex) * (this is true of Golf too--I never noticed) the psect named STACKS is unused. That is wasting 1500 bytes of RAM. * The actual stacks are allocated out of the module named os_heap. That is using 20000 bytes. See if you have the command "heap free" . That will tell you how much you can reduce that heap size by (but of course you want to leave some!) You can change the size in FreeRTOSConfig.h. Change "configTOTAL_HEAP_SIZE" Right now it is double what I had it at (it is 128K, was 64K) * I don't see a problem with flash or RAM memory. It says you have 10c112 bytes unused in flash and 932b unused in RAM. If we need to find some available memory, we can probably do it, but I don't see a problem here right now. Your "out of memory" must be a runtime message? Exactly what does that error look like? Is it in the file system (i.e. MRAM)? That is a totally different story. You might try "get mram size" to see if it matches the amount you think you have. The MRAM code (if I remember correctly) fixes itself up based on the size and number of MRAM chips, so if one or more are not working it might just quietly compensate. 73, Burns Fisher, WB1FJ *AMSAT(R) Engineering -- Flight Software* On Tue, Jan 16, 2024 at 2:30 PM Bob Stricklin via pacsat-dev < pacsat-dev(a)amsat.org> wrote: > Here is the map file you were looking for. > > > > Bob > > > > *From:* Burns Fisher (AMSAT) via pacsat-dev <pacsat-dev(a)amsat.org> > *Sent:* Tuesday, January 16, 2024 12:04 PM > *To:* Bob Stricklin <bstrick(a)n5brg.com> > *Cc:* Pacsat Dev <pacsat-dev(a)amsat.org> > *Subject:* [pacsat-dev] Re: Memory Problem on PacSatSW > > > > The MRAMmap that you sent has nothing to do with the linker complaining. > MRAM is totally external and the linker knows nothing about it. > > > > I did not know about View/Memory that Jim pointed out.

Chris, Your comments are the direction we need to move towards. I would like to just hack out what I can to make it build and load so I can test chip interface. Will be looking at doing this. I want to get to the point that when I take something out that green bar moves to the left. This bar is red when you exceed available memory and probably yellow just before you do. I worry the bar is based on inputs and not actual linker results. I agree constants want help much but if there are any tables of fixed data that can be helpful. The other thing to do is code with numbers and not use variables. Again, not much savings but just a coding style. The heap space and swap is set for 0x800 each. I tried making this 0x100 each and did not see a change in the Green bar. This seems like a problem.

Faking Memory Size

You can see the file I edited and the change I made to make CCS build the project so I could see how much memory it used. This file and info is initially supplied by HCG. I am getting exact same information I see in Launchpad code and I see no reason for it to be much different. Bob

Memory File Linker
by Bob Stricklin 16 Jan '24

Burns, Tied up with doctors visit here earlier. Going to forward a couple of files related to this. I do not see a MAP file generated by the Linker. I feel there should be one some place. The only thing I see related to this is the Memory Allocation relating memory use to code routines. Using the same input of code here used by Launchpad and PacSatSW project with HCG changes. I plan to put my code on GitHub today. Have not tried to manually modify the Memory Map file. I have project set for automatic and my understanding is CCS does this for you. I will send a second email showing changes I made to make CCS think I had more memory and build project. Bob

Just a reminder, Chris, that if you are using the OS heap (as gets used for stacks) reducing what you request will not reduce the memory that the linker sees being used. You have to also reduce the heap size. 73, Burns Fisher, WB1FJ *AMSAT(R) Engineering -- Flight Software* On Tue, Jan 16, 2024 at 11:38 AM Chris Thompson via pacsat-dev < pacsat-dev(a)amsat.org> wrote: > I expect the code could be drastically optimized to reduce memory usage. > It's fairly complex and I opted for simple static memory allocation.

OK will have a look at this. Found this note also which probably applies to us also: On MSP430 (or other) devices with limited RAM, the linker may fail to allocate the .bss or other sections allocated to RAM. The .bss section is for uninitialized global variables, and goes into RAM, along with stack (.stack) and heap (.sysmem) sections . If the code has a large number of global variables, you may run out of RAM space. If this is the case, you may consider making some of the variables const so they go into the .const section instead (which gets placed in FLASH instead of RAM).

Is there a variant of the TMS570LS0914 that has more memory? That might be the easiest fix. Note that what you call "external memory", really MRAM, is relatively slow. MRAM is also fairly small. It's big advantage is that it is non-volatile and fairly radiation resistant (and has a lot of space heritage with AMSAT and others). 73, Burns Fisher, WB1FJ *AMSAT(R) Engineering -- Flight Software* On Mon, Jan 15, 2024 at 4:16 PM Jim McCullers via pacsat-dev < pacsat-dev(a)amsat.org> wrote: > Since it ran and worked I never explored memory usage. > > I have to reconnect the development system and will cross check your > findings. > > That’s far more ram than I would have expected. > > > > Jim > > WA4CWI > > > > > > Looks like we have an issue with memory usage in RAM > > > > If you load up CCS with the current project PacSatSW and build it then you > can select VIEW -> Memory Allocation and look at the tab.

Yes, I am tracking Problems and also watching Console as things compile and post. Errors show up in Console that do not make it to Problems I noticed. I am now getting a clean build. You can turn all windows on in View Tab and with the icons on the left of screen. CCS arbitrarily turns them off I notice. Probably a way to override this with a personal IDE setup. I think under Window. I am not trying to say I have masted this. Still learning. Like I use the project view all the time and finally found the paste/folder icon on the left brings it up. I was using Window - ShowView. I have learned we are good on I2C and the Serial Port. Just have to check addresses used in CCS devices . H files. Working on SPI for AX5043s now and making sure there are no outputs in HalCoGen config on pins that will be driving outputs from other devices. I see what needs to be done just need to work through it. Hope to try testing this tomorrow. Any feedback is appreciated. I posted an order to mouser today for a few parts needed. Will have them Monday Maybe. Weather here may stop delivery. Ice possible.

That location on disk is on my Linux build system.

I think console routines fetches the time that the compile happened, so rebuilding it forces it to include the time of the compile regardless of whether anything else has changed in that routine. Touch should just change the date on the file so make will always compile it. 73, Burns Fisher, WB1FJ *AMSAT(R) Engineering -- Flight Software* On Thu, Jan 11, 2024 at 10:38 PM Bob Stricklin via pacsat-dev < pacsat-dev(a)amsat.org> wrote: > > Here is the location of the “touch” issue? > > What is this for? > > Why does it break things if you remove it? > > ----------------------------------------------------------- > > pacsat-dev mailing list -- pacsat-dev(a)amsat.org > View archives of this mailing list at > https://mailman.amsat.org/hyperkitty/list/pacsat-dev@amsat.org > To unsubscribe send an email to pacsat-dev-leave(a)amsat.org > Manage all of your AMSAT-NA mailing list preferences at > https://mailman.amsat.org >
