This is the correct method. Please attach your service file and any logs. Also explain what you expect to happen and what is actually happening.

I want to adjust the ARM so that it starts an application automatically after startup (or login). There seems to be more than one way to do that, two of which are covered in your wiki. I tried applying them with a dummy script in @/... - OÇ 12:09 PM Software Development: RE: Kernel panics on custom board: "No init found. Try passing init= option to kernel"
- Hi,
I solved this problem by writing the JFFS2 image to the NAND partition via the MTD Utilities in Linux, instead of U-Boot. Now, I can boot up Linux properly with the file system.
Thanks for your help. - OÇ 12:08 PM Software Development: RE: Linux Boot Parameter and NAND Partition

- You can manually update the nand partition tables by changing the file arch/arm/mach-davinci/board-mityomapl138.c and look for @mityomapl138_nandflash_partition@.

From the @mtdparts@ command of the U-Boot. It is also consistent with environment variable of the same name.

Yes I agree with you. Given that parition table, I would expect you to have to use mtdblock1.

I have a general question about Linux on MityDsp, which might help me solve "the problem I consulted you about before.":https://support.criticallink.com/redmine/boards/10/topics/5615

I suggest you do some research into nand and ECC. This might be a good starting place.

I'm afraid I have no idea what an ECC strength is. I've read "this documentation,":https://www.kernel.org/doc/Documentation/devicet...

The kernel and u-boot both have to use the same ECC strength. You can possibly use our kernel if you can figure out how to configure the nand correctly but I don't think we can be of much help here.

I couldn't reply sooner because I've been handling some other kernel-related problems by using NFS as a temporary solution.
The custom board is rather similar to Critical Link's MityDsp-L138F in terms of included peripherals et...
