Ok Burns. Will check soon. At the gym and will be home in about 30 minutes.

Good that you fixed this.

I added 20k pull-up on MOSI and security chip. Also moved the enable lines on the two supply control chips will give details on that later.

 I got one MRAM working, specifically #1. I apparently fixed the chip select for that one.

Please try "get mram sr" with X0.1p. If they say something other than 0xff, they are probably working. Don't mess with the other MRAM commands unless it sees all the MRAMs. I think a lot of that code assumes there are 4 good MRAMs.

In the meantime, I now KNOW that most the SPI bus is ~good on my board, so I'll focus a bit more on the chip selects for 0 and 2. If I have time, I'll see if I can get some of the other tests working for only some MRAMs.

Regarding the MRAM. I at first thought that you said "okay", but now I think you said zero K. I originally set up the MRAM code to figure out the size of the MRAMs, whether they needed 2 or 3 address bytes, and how many were present. But I only had the one example of Jim's launchpad board, so I'm not surprised it is not quite right for larger MRAMs and especially if the failing MRAMs are not in order (i.e. 0 and 1 work, 2 and 3 do not). But since none work on my board, I could not do anything more. As soon as I can get a board with working MRAMs, I'll fix all that. Also with all the MRAM errors that I get I have disabled a number of the tasks because they quickly failed and reset the processor. I'll fix that when I get a working MRAM board.

Regarding the 5043: Did you do "test ax"? That shows a couple registers from each of the 5043s which we know the value of. I think you can say "get ax 2" to read AX5043 #2, but I'm less sure about that. I did not display all 5 just because I did not know the correct values anyway, and it would just run off the bottom of the screen :-)

More in a separate mailing.

I was setting things up initially with my GIT username and password and apparently you must in CCS.

I have built and run Version ‘o’.

I am seeing data back from 2 of the AX5043s. Probably need to expand code to work with all 4 devices. Later.

get ax returns this …. screen capture

<Screenshot from 2024-02-08 02-56-00.png>

get mram size just returns two of the mram 0 and 2 and indicates their size is 0k. test mram 1 42 seems to run saying Write starting at etc and goes from 0KB to 1024KB. Then it does a Read in same area and does not report any errors but says: Test is OK! Time is 75 seconds. MRAM chips are 4 meg so maybe code only setup for 1 meg.

More testing on hardware later today.

Yes, the same branch. What errors are you getting? 73,

Confirm for me the branch you are working with is WB1FJ_Port_to_Blinky

I am having an issue getting a clean build. I know you were still working CS problem but I am trying to get the GIT build process to work properly.

I'm reasonably sure that I have the chip select lines screwed up in s/w. I have band rehearsal tonight, so I won't be able to do anything till tomorrow.

Pacsat>test ax AX5043 #0: Revision=7, scratch=7 AX5043 #1: Revision=7, scratch=7 AX5043 #2: Revision=119, scratch=119 AX5043 #3: Revision=7, scratch=7 AX5043 #4: Revision=119, scratch=119 AX5043 #5: Revision=7, scratch=7

This is what it looks like. However the numbers are all wrong. I'm not sure how they can be other than right or 0xff, but something is screwed up. The Revision should be 0x51, which would be printed in decimal as 81. The scratch register, I wrote the AX5043 number into, so each one should read the same as the first number in the line, i.e. 0, 1, 2, 3, 4, 5.

You might as well try it on yours Bob. In the meantime, I'll try to see if I can tell anything on mine.
