hippo,

do you have a patch for 2.6.12? i'm going to take a shot at looking at the differences between .11 and .12. 2.6.11 was put out by microtronix, right? i'm worried that maybe they stuck in some specific hacks to get it working that weren't carried over to any other versions. if i can get up to .12, i will compare .11 and .12 to see if i can spot anything.

The first patch , linux-2.6.11-nios2-01.diff , come from 2.6.x , is believed to be clean, with only uart and altcf driver.

The next patch, linux-2.6.12-nios2-02.diff, is the minimal changes that is required to compile 2.6.12.

The linux-2.6.11 passed the tests, but linux-2.6.12 failed on one of my board.
