I am not super familiar with ubifs, but it seems it can be a bit tricky to master. I know it can be done, as some of our customers are using it. One thing I have seen is to make sure the subpage size is the same as the page size (4k... - KW 07:14 PM Software Development: RE: Writing UBIFS rootfs to AM3354 with 512MB NAND
- Here some additional information that maybe helpful. After ubiformat the erase blocks are all marked BAD.

- Hi Tim,
I've been following this steps and it looks like the ubi.img is writing to NAND, but I get error 28 (No space left on device) when trying to attach. Here are my steps for writing ubi.img: - TI 02:53 PM Software Development: RE: Writing UBIFS rootfs to AM3354 with 512MB NAND

TI has a few pages on this.. check out http://processors.wiki.ti.com/index.php/UBIFS_Support
As long as you program the ubifs from linux there should not be an issue.
There is currently a disconnect between ECC used by u-boot and ... - What's the procedure for creating and writing the Linux UBIFS rootfs to the AM3354 512MB NAND? What ECC is used for the UBIFS partitions?

- We are moving our design away from the Vitesse ethernet chip (VSC8601) included on the Am3359 dev board to a Texas Instruments TLK110.
We know these are used with AM3359 successfully by TI;

- We are currently using the 3.1 kernel from the critical link git.
Thanks for the info!

- It seem the git diif shows me the differences between what I originally cloned from Critical Link and my current changes in the directory.

Software Development: RE: Difficulty in flashing MLO and U-Boot to the AM3354 with 512MB NAND
- Hey Jonathan,
I've simply modified the files with-in the u-boot-mityarm-335x directory. Would there be
any way to diff the changes made to the repo?
Thanks,
John C.

- John,
Depending on how you did your changes you should be able to do a _git pull_ and git will update the repo, merging with your changes where necessary.

- What version of the kernel are you running?
This might be of some interest.

- I'll add to what Mike said a wee bit.
You can use the mtdparts u-boot command to display (and set) mtdparts in u-boot [ see http://www.denx.de/wiki/view/DULG/UBootCmdGroupFlash#Section_5.9.3.5. ]
These _should_ line up with the linux v... - MW 07:23 PM Software Development: RE: booting 3359 from NAND only
- Hi Keith,
I don't think the NAND is actually physically partitioned. It's more of a "table" as you say.
The Kernel will use a default partitioning as coded in the arch/arm/mach-davinci/board-mityarm335x.c file. However, you can co... - KF 06:32 PM Software Development: RE: booting 3359 from NAND only
- Hi Tim,
I have just been looking at flashing from the mmc, however, I have managed to confuse myself even more!
From the linux running on the SD card if I use "mtdinfo -au" it tells me that the file system is in mtd8, not mtd7 (there ... - KF 06:09 AM Software Development: RE: booting 3359 from NAND only
- Hi Tim,
Thanks for the quick reply. When you say keep the EEC mode consistent between the u-boot and the kernel is this just the EEC mode used when they were written to NAND, or something more sinister such as something in the way they ... -

We just ran across this exact problem with our newly purchased 3354 module(we had been using the 3359's).

Make sure that the ECC mode is consistent between u-boot (where you are flashing the ubifs) and the kernel. Alternatively, you could flash the ubifs image from linux (boot from mmc and then flash).

I have been trying to get my 3359 system up and running from NAND, using a combination of Critical Link and TI info, and I am having a few issues.
