Writing to Flash Filesystem on MPC8313E-RDB?

[MarkB]

On the default setup of the MPC8313E-RDB I see:

/dev/ram0 mounted as /
rwfs mounted as /mnt/rwfs
shm mounted as /dev/shm

How can I see which partition is mounted to which memory device (NAND/NOR)?
How can I get access to the NAND and NOR flash memory so that I can write a simple file?

A 'touch my_file' creates the file but it is destroyed on every reboot.
I've tried 'touch /my_file' and 'touch /mnt/rwfs/my_file' and 'touch /dev/shm/my_file' and every time the file is destroyed.  Am I really writing into DDR?  How can I create a flash partition to write it?

Once I have a modified .dts file is there a guide that says what to do with it to get it into the processor on the RDB?

When you compile the kernel you obtain the dtb file, you can find it on the boot directory. This is the file you must pass to the kernel on boot using mboot command from uboot. One parameter of the mboot command is the dtb file.

Hello MarkB

It's in my todo list. Now I´m doing other thing but I saw some about it. I think that I'll use module mtd on nand flash. I saw that the flash partition would be defined on dts/dtb file.

I hope it'll help you. Please, report us your progress.

Best regard,
