Title: Boot from 2nd partition
Post by: Lilian on October 28, 2013, 11:39:45 PM

Hi everyone,

Is there a way to boot the linux kernel from the 2nd partition (instead of the 1st one) of the sdcard ?

Thank you for any advice,
Lilian

There is imx23 suppport in u-boot. (Haven't tested yet.) Is this what you have in mind?

What other reason is there to not boot from the first partition?

Hi Lilian,

The iMX233 ROM will boot from the first primary partition on your uSD-card that's marked as type 53, and which contains valid boot-stream (bootlets+kernel, or U-Boot). I've tried to put U-boot on all 4 primary partitions and it worked for me.

Here's one example, where my board boots from the 4th partition:

Device Boot Start End Blocks Id System
/dev/sdb1 2048 34815 16384 b W95 FAT32
/dev/sdb2 34816 67583 16384 b W95 FAT32
/dev/sdb3 67584 100351 16384 b W95 FAT32
/dev/sdb4 100352 133119 16384 53 OnTrack DM6 Aux3

Hope this helps. Regards,
picmaster
