ECC error during mounting UBIFS volume

Dear Balaji,
What is your processor ?
That post was for OMAPL138 and I hope you are using AM335x.

BTW, OMAPL138 has support 456MHz and 300MHz operating frequency but AM335x does 1GHz.

Can you please provide the complete log and when you are getting into this error etc., ?

Dear Titus,

I am using TMS320DM8168 Processor.

Balaji

Dear Balaji,
Can you please provide the complete log and when you are getting into this error etc., ?
What is your kernel version ?

Dear Titus

 

 Linux version 2.6.37

 I have attached error log of DM8168.

Dear Titus,

I am waiting for your reply on previous post.

Dear Balaji,
Please make sure that you have the following patch in your kernel version.
lists.infradead.org/.../005984.html

Also please make sure that you have correctly configured the ubinze.cfg file for UBI conversion.
Able to boot with different "jffs2" or "yaffs2" filesystem ?

can you mail me where to change clk to 456 MHz instead of 300 MHz

Your DDR3 default frequency (in u-boot) is 796MHz (not 456MHz) and you can lower it to 675,531,400MHz, see the below wiki for more details:

Dear Sir,

Do you have source code of compression and decompression in CCS compiler? since spectrum digital provide sample code of DDR, NAND Flash and RTC. Please attache the file if you have it.

Balaji,

I am not sure I understand your request. Could you give more info? Is this anyhow related to DDR3 clock frequency and/or UBI ECC error?

Dear Sir,

I got source code from spectrum digital (support.spectrumdigital.com/.../) for testing DDR3, NAND Flash and RTC in Code composer studio. They don't have code for codec(compression and decompression) in CCS. can you provide me if you have it.

Regards
Balaji

Balaji,

Sorry, I do not have CCS code for codec (HDVICP2 engine).

Dear Pavel,

I have DM8168 Reference Manual for DM8168 but i cannot find the reference manual of codec of DM8168 with register details. Can you mail me where to download the files?

Balaji

Hi Balaji,

This is linux forum, and your question is not related to linux kernel. I would recommend you to open new e2e thread (regarding codec manual) in the DM816x forum.
