Wolfgang,
I tried the following versions on our old board and found that
booting linux stops working from 1.3.2-rc1. So, some change between
1.3.1 and 1.3.2-rc1 is causing my problem. Can you give me any
pointers as to where to look?
1.0.0: works
1.2.0: works
1.3.0: works
1.3.1: works
1.3.2-rc1: does not work
1.3.2: does not work
1.3.3: does not work
