Good catch. I'd guess that your service type should be @simple@ instead of oneshot since your program isn't expected to exit. But idle is similar to simple and that ... - OÇ 08:39 AM Software Development: RE: Launching Linux Application on Startup

You're right. This one was already working, but I didn't realize it because it couldn't print anything. Adding "@StandardOutput=tty@" to the service file solved this. Here's my service file:

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.

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