[yocto] Freescale T1040RDB Failed to mount UBIFS

Fri Apr 10 11:10:34 PDT 2015

Hi Sandeep,

Thank you for your quick response.
It's true SDK1.7 doesn't mention  using UBIFS with Nand Flash. But we decide to use the Nand Flash on Board.
Can you send me your bootcmd  and boot log running T4240RDB please?

Thanks
Leo

Hi Leo,

I walked through the QorIQ-SDK-1.7 manual section 3.4.16 for T1040RDB doesn't say anything on the NAND flash procedure. I can see the NOR Flash memory map and flash procedure.

I use T4240RDB with NOR flash works great.

Please contact your local Freescale FAE for more support and post the question is Freescale forum you might get some help.

I built UBIFS rootfs for T1040RDB, apparently I got 2 rootfs images:
1. fsl-image-core-t1040rdb-20150408204106.rootfs.ubi
2. fsl-image-core-t1040rdb-20150408204106.rootfs.ubifs
So I updated  Nand Flash rootfs Partition with  image :fsl-image-core-t1040rdb-20150408204106.rootfs.ubifs

Uboot bootcmd : bootcmd=setenv bootargs noinitrd ip=off mem=256M rootwait=1 rw ubi.mtd=7,4096 rootfstype=ubifs root=ubi0:rootfs console=$consoledev,$baudrate $othbootargs;nand read.e $loadaddr $kernel_addr $kernel_size;nand read.e $fdtaddr $fdt_addr $fdt_size;bootm $loadaddr - $fdtaddr

My question is

1.       which image should be flashed to Nand, xxx.ubi or xxx.ubifs?

2.       what does the error blow mean?

Built uboot and kernel to support ubifs and reset  T1040RDB, but I got error blow:
