Tool/software: Linux
I have custom board whose MCU is am3352. I am working on sdk 02.00.02.11
I am trying to boot linux system by using SPI Nor Flash.
I succeeded in writing MLO.byteswap, u-boot.img, dtb, and zImage on SPI Nor Flash.
However, I couldn't mount the file-system on Linux startup.
I wrote my rootfs.jffs2 on flash's 6th partition.
So, I set the spiroot to '/dev/mtdblock6 rw'.
I don't know what mistake I made on my system.
It's possible to mount the 6th partition (file-system) of flash after finishing entire booting. So I'm sure that the file-system is well-written
I attatched the kernel log, u-boot env, and dts file.
Anyone help me.. I couldn't find the mtdblock series on "List of all partitions" of kernel log.
This is kernel booting log
