What is difference from TWR-K70F120M Rev 1 vs TWR-K70F120M Rev C

[muratdemirtaş]

Hello friends,

I'm trying boot ucLinux to our TWR-K70F120M Rev 1 boards. I can successfully compile kernel and u-boots but. When i flashing u-boot to integrated flash, i see nand blocking errors. This errors cant seen from emcraft u-boot 1.3.2 tags release. 

Are the differences between revisions a reason for not using nand flash?. u-boot 1.3.2 version can load linux images successfully without nand flash load support. I guess after u-boot releases was designed for TWR-K70F120M Rev C. What can i do? Thanks.

So this must be different problem.

Hi,

From what I know, there has no much difference between the Rev A and Rev C of the TWR-K70F120M. All the difference between the Revs had been listed on the first page of the schematic.

All the changes are nothing to do with the NAND flash. So what you mean of the NAND flash change for U-boot?
