Hi i am navee patel

I am trying to boot android in imx233 with the lms350 screen i have changed the screen driver also but i am not able to boot the android

the kernel boot arguments are like this

console=ttyAM0,115200 root=/dev/mmcblk0p2 rw rootwait lcd_panel=lms430 ssp1=mmc init=/init rootfstype=ext2

the error i am getting is like as follows

where are you putting your root filesystem? I think it is not in mmcblk0p2. Either you have your rootfs on mmcblk0p2 or change the kernel command line option to whereever your rootfile system is.

I have the exact same problem but I know for sure that my RFS is on mmcblk0p2.

I think this is an issue with the actual SD card.

I've similar issue fixed with iMX28EVK, hope this helps.

The reason of it is mmcblk0 is discovered as read-only (see end of line mmcblk0: mmc0:e624 SU04G 3.69 GiB (ro)). If it is read-write than no info at the end of this line should be printed.

Check hardware and software pins config.

I found write protect state of SD card in device.c mxs_mmc_platform_data.get_wp function (mxs_mmc_get_wp_ssp0 on iMX28).

Second thing, don't know how it is on imx233, but in iMX28 rootfs is on 3-rd partition (mmcblk0p3).
