Thats good.

Just need to replace MRAM on that board could be the soldering or the overvoltage they experienced early on.

Ok, looks like two of the MRAMs are ok, and two are not for whatever reason.   Oh, I bet I know...I think I got the chip select lines wrong on one or two of them.  Funny the temp actually looks ok despite the error.    In the middle of checking something else.  Will get back after a bit more testing.

Oh, I just sent you a mail before seeing this.

Wow!  Looks like there may be something wrong with my board.  Could you do "get mram sr" please?  You could try "get temp" also.

I'm not sure if those are the right values for the DCT (the AX5043).  I know I had a quick way at one point that I could tell if one particular register was correct.  I'll see if I can find it.

After getting TX and RX connected correctly now working. Do not know what the correct report back is but here is some checks...

This board has four 4Mb MRAMs installed.
