- Attached are boot logs from every combination of carrier board and image. The processor always reboots with my image on either carrier board, so I believe it is a problem with the image.
I'll work on stripping out all my changes to tr...

- My system is powered by a DC power supply at 3.7V.
Thanks for the suggestions about trying all combinations of my image vs prebuilt image and dev board vs. my carrier board. That should at least narrow it down on HW vs. SW. I'll do th... - GG 06:23 PM MitySOM-QC6490 Software Development: RE: Processor rebooting

Sorry to hear you're having this issues. Thank you for providing these details so we can get the bottom of it quickly.

Apologies on the delay for your first question, my colleague who's more familiar with the DMA example is looking into that now. I'm not sure yet when we'll have an answer for you, but he is able to (intermittently) reproduce t... - MK 06:17 PM MitySOM-A5 Software Development: RE: make_sd.sh doesn't take command line parameters

Yesterday, we din't pay attention, but actually DMA test fails on Rx side. We run few times and it faild always in the same index.
We will try on other unit (we have 2), but do you have any idea why it can fail??

Thanks for the feedback, I can definitely see how in this case that wording was misleading. In general it is not mandatory (e.g., some device tree changes do not require an updated Image file), but I'll make a note to see if w...

Just to clarify:

It's fine to have multiple folders in @/lib/modules@, although you could delete the yocto-standard one if you wanted to reclaim the storage space.

Glad to hear the base design is working now! And no problem asking questions, most likely they'll help someone else too. :)

That USB dongle should be fine. Our reference design SD card should have the drivers pre-installed for that to work.

Happy to help!
It looks like this is a case of the JIC and RBF files not matching.

I've uploaded mitysom-a5e-ref-dma.tar.gz (1.29G) - I've compressed the whole folder.

The build seems to have partially worked since it was able to boot into U-Boot proper after the SPL, but past that it seems unable to load anything from the SD card for some reason.

Did the script produce sd_card.img.gz instead? You're giving it flags for both gzip (@-g@) and zip (@-z@), and gzip should be taking precedence.
