I'm trying to boot from u-boot on a Raspberry Pi 3. But for some reason
it isn't autobooting on the SD-card.
Is it possible to get more debug output on the screen console? I don't
have a serial console at the moment.
The output on the screen is:
Net: No ehternet found.
USB: Core Release 2.80a
scanning bus 0 for devices... 4 USB Devices found
scanning usb for storage devices... 0 Storage Device(s) found
Hit any key to stop autoboot: 0
Shouldn't it mention mmc somewhere in the boot message?
The first command I type on the prompt is always failing, it's not
outputting anything. Just a new prompt on the next line. The next
commands i type in are working. Which seems strange.
I got boot.scr set up right, except graphic settings which are wrong. It
is booting the kernel when I type 'run bootcmd'. But only after I type
in another command before it.
It seems like it's not detecting the SD-card (mmc0) until I have typed
anything into the prompt.
Do I have to set any other env variable for it to autoboot? I would have
printed the output of printenv here, but since I don't have a serial
console, retyping everything is very time consuming.
printenv seems to have the right settings. It's basically a full console
screen of variables. It just doesn't seem to load them until I type in
another command before it.
boot_targets=mmc0 usb0 pxe dhcp
Which seems right to me.
I compiled the latest u-boot from github.
If you need more info please let me know and I'll post it.
Hope that anyone can point me in the right direction here. Would really
