Hi,
I’m getting the following error on trying to boot Linux from SD Card o VF50:
Colibri VFxx # run sdboot
Booting from MMC/SD card...
** Invalid partition 2 **
Colibri VFxx #
I followed the instruction on Linux - Booting | Toradex Developer Center
$ sudo parted /dev/sdX mklabel gpt
$ sudo parted /dev/sdX mkpart “colibri ext3 1 -1”
$ sudo mkfs.ext3 /dev/sdX1
Should I format the SD card with two partitions? The above instruction does not work to VF50?
Best regards
For the Colibri Vybrid, we have format_sd script in our release image. It has a -f option which can also create and format a second partition with the rootfs included on second partition and the first partition having the necessary files for update. You can execute the script as follows.
./format_sd.sh -f -d /dev/mmcblk0
The output from help option
Formats and fills a SD card with files for flashing the internal NAND of a
Colibri VFxx. Optionally creates a rootfs partition to allow booting and taking
kernel and rootfs from SD card.
ALL DATA ON THE DEVICE GIVEN WITH -d WILL BE DELETED!!
Requires a running U-Boot on the target. Either one already flashed on the NAND
or strapping the board to boot from SD card and booting U-Boot from the card
(only possible on older samples without blown boot fuses).
-h : Prints this message
-d FILE : device file of the SD card
-f : additionally copy the rootfs into the second partition
-s : optimise file system for 128MB NAND, increases usable space
on VF50 module a little, but on VF61 uses also only 128MB
Example "./format_sd.sh -d /dev/mmcblk0" prepares the SD card /dev/mmcblk0
A SD card thus created can then be used directly to boot from by running
run sdboot
from the u-boot command prompt.
Hi,
I’ve just also booted formatting the sd card in this way:
