Well, you and Burns did a lot of the work of testing and debugging. If I hadn't removed the initMRAM() call from main.c it would have gone a lot better. It reminds me of the olden days when the people that wrote the code sent it to another group to punch onto cards and submit it and bring you back the results. It does make you review your code more carefully. We need to figure out what to do with the volume name and maybe tweak partition sizes. But it could probably go to the main branch at this point. Thanks for working on this, -corey

Reading and writing works fine! This looks fantastic Corey. No doubt there is a lot of work still to tweak all the settings and make sure it will be reliable, but my initial impression is very good. Well done. 73 Chris On Sat, Apr 8, 2023 at 4:50 PM Chris Thompson via pacsat-dev < pacsat-dev(a)amsat.org> wrote: > Burns, > > I pulled your branch directly and now it runs without the errors. > Something strange had happened in the merge. > > Anyway, that was the issue.

Burns, I pulled your branch directly and now it runs without the errors. Something strange had happened in the merge. Anyway, that was the issue. Now I can write to the file system. You do need / as the volume name and / as the root dir. So //test_file worked. /test_file did not. Despite the documentation suggesting it would. I'll try to read it back next. 73 Chris On Sat, Apr 8, 2023 at 4:38 PM Burns Fisher (AMSAT) via pacsat-dev < pacsat-dev(a)amsat.org> wrote: > Better check if there is a call to initMRAM in main.c immediately after > SPIInit(MRAM3Dev).

Better check if there is a call to initMRAM in main.c immediately after SPIInit(MRAM3Dev). It is line 206 for me. That's what I had to do in order to avoid all the errors at startup. 73, Burns Fisher, WB1FJ *AMSAT(R) Engineering -- Flight Software* On Sat, Apr 8, 2023 at 4:26 PM Chris Thompson via pacsat-dev < pacsat-dev(a)amsat.org> wrote: > From what I can tell in the developer guide, "//test_file" should have > worked.

From what I can tell in the developer guide, "//test_file" should have worked. But so should "/test_file".

Burns, I think the initMRAM() is there. I merged your branch in. I see the function call in ConsolTask() right after the SPInit() calls for the MRAMs. But I also see a lot of MRAM errors at boot. Error 19s and Error 20s...

I tried a simple example but I can't open a file. Is there a volume name that I need to specify? I presume you don't need to create a directory. Here is the code, but the open fails with "No such file or directory" // TEST File System char *test_string = "This is data"; int32_t fp; printf("FS Test: Writing:\n"); fp = red_open("/test_file", RED_O_CREAT | RED_O_WRONLY); if (fp != -1) { printf("Writing string\n"); int32_t numOfBytesWritten = red_write(fp, test_string, strlen(test_string)); if (numOfBytesWritten == strlen(test_string)) { printf("Success\n"); } else { printf("Write returned: %d\n",numOfBytesWritten); if (numOfBytesWritten == -1) printf("Unable to write to file: %s\n", red_strerror(red_errno)); } int32_t rc = red_close(fp); if (rc != 0) { printf("Unable to close file: %s\n", red_strerror(red_errno)); } } else { printf("Unable to open file: %s\n", red_strerror(red_errno)); } Any thoughts? 73 Chris On Fri, Apr 7, 2023 at 5:10 PM Burns Fisher (AMSAT) via pacsat-dev < pacsat-dev(a)amsat.org> wrote: > >I assumed that since this was ARM it was little endian. > > Yeah, I would have too.

Jonathan, did I send you the extra Launchpad that I ended up with? In any case, do you want to give one to Corey? Corey, you may have to solder on some .1" header pins for Jim's board to have all the required connections. I know the headers are DNP around the outside where they are not used, but I'm not sure that all the inside ones are there either. 73, Burns Fisher, WB1FJ *AMSAT(R) Engineering -- Flight Software* On Fri, Apr 7, 2023 at 12:30 PM Corey Minyard via pacsat-dev < pacsat-dev(a)amsat.org> wrote: > I have the filesystem code mostly ready.

Ok, the initial MRAM errors (and I think actually a fs error that did not show) came because initMRAM has to be called way early in main before any calls are made to readMRAM (since otherwise "numberOfMRAMs" has not been initialized so getPartitionOffset fails. After I did that the fs was not correctly formatted anymore and format fs took a bit longer than it did before. But now it all seems well. Again, that is pushed up to the repo as BFFileSystem. Feel free to merge.

Jonathan, Thanks for your email on this topic. These connectors mainly eat up a lot of board space. Reducing the pin count to something more realistic should befit all. Every pin you have in a connector is a potential reliability issue. Reliability in the actual connection interface and in the increase of complexity of the electrical design. Each pin with routed signals requires more effort to rout signals on the PCB. These connectors are adding mass to one side of the CubeSat moving the center of gravity. This will effect the orbital dynamics and stabilization systems. Some AMSAT designs use multiple bus systems, RS232, I2C, CAN, IO signals. These busses require different interface chips, power voltages, power consumption, firmware, and user knowledge. Reducing to a single communication bus system would reduce pin count, chip count, power needs and improve reliability. The connector systems marketed are not all equal. If a 104 pin standard is used then there should also be a specification for which connector are to be used. This will define the pin size, plating layers - nickel gold, socket sizes and pin hardness. I suggest using the pin size that is soldered in place. If the press pin socket pins/holes are used then they should be soldered after assembly. During prototype and production of flight hardware these connectors are difficult to work with. Each board/connector will have to be disassembly and reassembly many times. We need Battery voltage, and an I2C (2 pins) possibly a signal ground, and possible a hard reset signal.

All that is true. At same time it's also true that if somebody is adding a component to their CubeSat it will most likely expecting boards with the PC-104 form factor. AMSAT is an exception but even then we had to partially adapt our boards to the PC-104 form factor for use by non-AMSAT organizations. > > When I'm at CubeSat Developers Workshop later this month, I'll do a survey.

I'd be interested if those who use PC104 actually use them throughout the satellite (i.e. they use them like Fox/Golf uses the QxN connectors where most of the signals pass through). Also what board spacing where these connectors are used if there is anything typical.

PC-104 "Standard"
by Jonathan Brandenburg 07 Apr '23

07 Apr '23

Following up on last night's conversation... When there is talk about CubeSats using the PC-104 standard, what that really means is the use of the PC-104 form factor in terms of board size, mounting hole placement, and the 2x2x26 connector. CubeSats don't adhere to any of the signalling or protocol aspects of PC-104 standards (including additional connectors defined in the PC-104 standard). There hasn't been any standards body define this form factor for Cubesats (as far as I know) so I imagine it just sort of grew organically from the first university satellites looking around for something to copy and noticed the small form-factor computer. As correctly noted, CubeSats don't standardize the use of the pins in the PC-104 connector but it seems like component manufacturers looked around to see how others had been using pins and followed suit. Thus if PACSAT is using I2C, power, and ground pins there will be little conflict. What I've seen is CubeSat component manufacturers offer an option sheet that allows the customer to select from a set of options. Along the lines of "put I2C pins here or there or do not connect" kind of options. I hear the comments about how "This a large connector!" and "How many pins are really needed?" and "How are they used by different components?" All that is true. At same time it's also true that if somebody is adding a component to their CubeSat it will most likely expecting boards with the PC-104 form factor. AMSAT is an exception but even then we had to partially adapt our boards to the PC-104 form factor for use by non-AMSAT organizations. When I'm at CubeSat Developers Workshop later this month, I'll do a survey. While I will see at least one university eschew the PC-104 form factor (because they're developing ALL the components in-house and prefer a plug-in-slot configuration because it simplifies assembly a lot) I expect most will have purchased the bus (including structure, C&DH, EPS, and any ADCS) which will be in the PC-104 form factor.

Filesystem interface to mram
by Corey Minyard 07 Apr '23

07 Apr '23

Here's the email I sent earlier. You can ignore the questions about MRAM. I have integrated the Reliance Edge filesystem into the PacSatSw repository in the "filesystem" branch. However, it is still missing the lower level interface to the mram devices. The main filesystem interface is in reliance-edge/include/redposix.h, I have enabled POSIX support without rename. It's pretty straightforward. You can get a copy of the Reliance Edge development document from https://www.tuxera.com/resources/reliance-edge-developers-guide/, but I don't think you need it. I have a copy, and I don't see that I can't redistribute it, so maybe I'll add it to the repository. Are we using the mram code in the deviceSupport directory? If so, the read and write operations (readMRAMWord, writeMRAMWord) don't have prototypes in the header. But I can fix that and integrate. Jonathan, I guess I'll need a launchpad and a board with the mram, since the qemu stuff didn't work out. -corey
