I know that this topic has been addressed before as in here:
One thing that I have to mention is that I overwrote the 16 GB micro SD card that that my Ultra96 board came with, with a petalinux build, with all of the proper BOOT.BIN and image.ub on partition 1 and the rootfs.ext4 on partition 2. I was not aware that the micro SD card that came with my Ultra96 contained the factory configuration. For all of the above I used fdisk.
After power on, I have no indications, with the LEDs on board, that the device is booting. Lights are on when I press SW4 but nothing flashes and I see no action on the blue LED.
I also found the “pre built” directory and used the BOOT.BIN and image.ub from there. No luck.
Instructions say to momentarily press SW3 but SW3 is not a push button but a select switch with two positions, which I have clearly set to the correct configuration ( I even tried the other configuration just in case but to no avail).
I have tried to set the SD card back to the factory defaults by following the instructions in:
The factory image that I downloaded was Ultra96_rev1_sdcard_image_180409.img and I used etcher to burn the image.
Still no result. It just appears that the system is either not looking to the SD card for boot instructions or that the boot instructions are incomplete. My guess is the former.
What would I do at this point?
