Hello, I am new to here, just found your post about PICO PI IMX7, but I got problem on it.
for Bootloader: U-Boot, it complains “no cc” when I run the compile for imx7d, so I understand that GCC is missing from system, however we already have a cross compiler installed in previous step, should we make more changes to Makefile (or ENV variables), or simply install the Ubuntu gcc? (I am on Ubuntu 20.04 LTS)
Before waiting for your answer, I tried to install Ubuntu gcc to move on and test, it does compile (though not sure if the outcome is good or not), moving on to “env default -f -a” I get the following:
=> env default -f -a

And I also get the following error
=> dfu 0 mmc 0
Couldn't find part #1 on mmc device #0
DFU entities configuration failed!
(partition table does not match dfu_alt_info?)
dfu - Device Firmware Upgrade
Usage:
dfu <USB_controller> [<interface> <dev>] [list]
- device firmware upgrade via <USB_controller>
on device <dev>, attached to interface
<interface>
[list] - list available alt settings
Tried to follow some other post and found following command but also not helped:
=> ums 0 mmc 0
** Invalid partition 1 **
So now I am unable to start the board with USB, what can be wrong here? Thanks
P.S. Sorry I have no idea why some fonts looking weird in my post.
