Hi,
My currently installed BSP is Apalis-iMX6_LXDE-Image 2.8b4 20190601 and I want update it to newest Toradex demo image.
The problem is I can only access to Serial Console and USB-Host port.
I try to update board with Legacy Image Format and this but I get error:

Apalis iMX6 # setenv drive 2
Apalis iMX6 # setenv setupdate 'fatload mmc ${drive}:1 ${loadaddr} flash_mmc.img; source ${loadaddr}'
Apalis iMX6 # saveenv
Saving Environment to MMC...
Writing to MMC(0)... done

after reboot

Apalis iMX6 # run setupdate
MMC: no card present
** Bad device mmc 2 **
## Executing script at 12000000
Wrong image format for "source" command

can I use USB Flah instead SD Card?

Is there any other ways to update current BSP with available ports.

Thanks.

Hi

Note that on the Ixora V1.0 the SD card slot had the number ‘2’. But Ixora V1.1 did change that to ‘1’.
So if you want to access read a file from the SD card it would be ‘fatload mmc 1:1’ not ‘fatload mmc 2:1’ as you do in your example.

Did you try to NOT change anything in the U-Boot environment and then use ‘run setupdate’?
That should first try to read the update script from the sd cards which fails and then initializes USB and tries to read from an USB Massstorage device.

E.g. reset the environment:

env default -a
saveenv

Then run setupdate with an USB Mass-Storage Device inserted should look like this:

Apalis iMX6 # run setupdate 
MMC: no card present
** Bad device mmc 1 **
MMC: no card present
** Bad device mmc 2 **
