u-boot reflash problem #634

Open Jorgeuri opened 2 years ago

Jorgeuri commented 2 years ago

Description

Working with the Coral SOM i accidentaly erased u-boot from the system. I'm trying to flash directly to the eMMC with the u-boot that is provided by google in "Get started with the System-on-Module" with uuu but it gets stuck in "Back to ROM, SDP" . Since i'm using a personal carrier i cant boot it with a SD , only with USB . Is there any new "u-boot" that i can use or are there any other alternatives ?

Hello @Jorgeuri we don't support UUU. Please try the fastboot, it's purpose is flashing the eMMC over USB, by following the regular steps at: https://coral.ai/docs/dev-board-mini/reflash/#first-time-setup. Thanks!

Hi @hjonnala , i erased the fastboot , is there another way to flash the eMMC without using SD ?

Hey @Jorgeuri did you get anywhere with uuu? I'm trying to do that now. Also if you put an image on an sd card that has uboot with fastboot, you can boot from that and use it to load the emmc with fastboot. The stock mendel sd card should work. I am interested in uuu for mass flashing at the "factory".
