BeagleBone Black Boot hangs: "Trying to boot from MMC1"

[lukasz139]

Hi,

I was trying to get my device tree loaded such that I can use PRU capabilities. One of the solutions that worked for me was given in this issue:

#76 (comment)

It worked for me, however, now during the boot I see following message on serial terminal:

U-Boot SPL 2018.01-00002-g9aa111a004 (Jan 20 2018 - 12:45:29)
Trying to boot from MMC1

It tries to boot from eMMC and nothing happens. I have tried with and without BOOT button.

Linux: kernel:[4.9.78-ti-r94]

Thank you in advance

I kinda remember this bug.. Does your BBB say "Embest or Element 14" on it? If so this got fixed last fall, please verify with this image:

@RobertCNelson Sorry to grave-dig, but I am encountering this problem on a BB AI-64. I updated U-Boot using these steps: https://forum.beagleboard.org/t/enable-uart-1-on-bb-ai-64/32997/3

Now I am stuck at boot:

init_env from device 17 not supported!
Starting ATF on ARM64 core...

Ah, the solution for me is perhaps here:
https://forum.beagleboard.org/t/ai-64-update-bricked-device/32329

It looks like console is disabled on my U-Boot, so I can't break into it via UART. I'll need to try to boot using the reset button.

@edgex004 use a flasher, early on (early 2022) we had some early u-boot builds that weren't ready..
