Hi,
I am currently using the Ultrazed-eg SOM with the IOCC, but I am starting to make customisations in preparation for a custom PCB.
Using AVNET's BSP as a base, I flash and boot from SD0, the internal eMMC. I then load the kernel and rootfs from a SATA. This is working fine.
As soon as I disable SD1, as the custom PCB will not have an SD card, I can no longer flash the eMMC via the SDK. The process halts at 'programming memory'.
I can flash the same image to the dual qSPI and it works. Just no longer flash the eMMC. From u-boot / Linux, I can see the eMMC is enabled when booting via qSPI.
If I enable SD1 again, I can then program the flash on SD0.

Thanks,
Richard.
