Hi Jaski,
Sorry about the delay getting back to you. I’ve found out problem - it was my mistake. While rushing around before the holiday break I had reset the uboot environment variables to stop my M4 code from running and I forgot to set my own .dtb again. I just found this out this morning as I was booting up the system again.
Thanks you for the support, I think I’m all good to spin my own carrier board now.
Cheers,
Mark
