Hi,

I am working on NAND Flash for AM335XEVM board. My NAND Flash Demo is working on

Rev 1.4A and Rec 1.6A

But not working on Rev 1.5C.

Is something different on Rev 1.5C or some magic jumper/switch settings are required?

Have you checked the CPLD profile switch: processors.wiki.ti.com/.../AM335x_General_Purpose_EVM_HW_User_Guide NAND is not accessible in profiles #2 and #3.

Hi Biser,

Here are the daughter board revisions

1.4A Evaluation Module contains 1.2A Daughter Board Revision
1.5C Evaluation Module contains 1.2B Daughter Board Revision

Also,

Yes, this is OK. I can't see no hardware reason why this shouldn't work on Rev. 1.5C. Maybe it's a problematic board.
