i.MX28 boot error on MMC custom board

[Matteo]

Hi,

I'm trying to boot from MMC card my linux kernel on a i.mx28 based custom board.

I'm trying to program by board with mfgTool, but the result is shown below (The entire log is attached in this post, "log.txt", I also attach the linuxrc file):

Freeing init memory: 128K

mount: mounting none on /sys failed: No such file or directory

mount: mounting none on /proc failed: No such file or directory

Starting UTP

mmc0: new high speed MMC card at address 0001

Internal error: Oops: 17 [#1]

last sysfs file:

Modules linked in:

CPU: 0    Not tainted  (2.6.35.3-571-gcca29a0 #24)

PC is at fsg_main_thread+0x994/0x22cc

LR is at fsg_main_thread+0x994/0x22cc

ecc. ecc.

From the entire log it seems that the linuxrc are starting but fail to mount /sys and /proc, after the kernel recognize the mmc card and the crashes.

Do you have any suggestions?

Also the log of the mfgTool report this error:

It seems that mfgTool fail to create the device node.

Do you have any suggestions?

Best regards,

Matteo.

Hi Matteo,

Your log shows:

Kernel command line: console=ttyAM0,115200 rdinit=/linuxrc root=/dev/mmcblk0p3 rw gpmi

mfg firmware updater_ivt.sb and updater.sb use initramfs. If you want to program the image to MMC, you can not use MMC as rootfs for updater_ivt.sb/updater.sb.  

If you choose mfg profile to build updater_ivt.sb/updater.sb, initramfs is set as default for target image and the default boot command is Kernel command line: console=ttyAM0,115200 rdinit=/linuxrc rw gpmi.

Please use mfg profile to build  updater_ivt.sb/updater.sb

Regards,

Grace
