I thought that the issue was solved but it seems that there is still
some weird shit happening. Here's what's working :
- Booting from SDcard with eMMC formated
- Booting from eMMC without an sdcard inserted
- Booting from eMMC with an sdcard inserted (no sdcard-boot button
press)
What's not working is booting from SDcard by pressing the button (to
force sdcard boot).
To me it's clearly some u-boot or bootrom problem
but maybe I'm wrong.
So if you boot from the sdcard but have u-boot on the eMMC so can do :
1) First confirmed that you booted off the SDCard, you should see
U-Boot SPL 2019.07 (Sep 27 2019 - 15:17:40 +0000)
Trying to boot from MMC1
MMC1 is the sdcard while MMC2 is the eMMC
2) Interrupt u-boot autoboot by pressing any key
3) Confirm that you have u-boot files on the eMMC by doing
=> fatls mmc 1
EFI/
106148 MLO
dtb/
700756 u-boot.img
364264 ubldr.bin
MLO is the file that we want to delete.
4) Delete MLO file
=> fatrm mmc 1 MLO
5) Confirm that it was deleted
=> fatls mmc 1
EFI/
dtb/
700756 u-boot.img
364264 ubldr.bin
Power cycle the board so you can boot from 12.1 sdcard image and update
your eMMC (or whatever you want to do).
