Hi

Thank you for your friendly mails, but I still have problems using a higher
cpu clock frequency in my A540. I've tried the things you told me and I've
upgraded to RO 3.1 but its still the same problem.
The selftest seems to be ok, but after that the screen stays black.
I think that maybe dma configuration goes wrong, but I'm not sure.
What can I do? I'm sure that my cpu can do 35 MHz or even more ?
Can I configure the A540 so that it takes some default values for dma?
By the may, my ram runs fine at 16.66 MHz.
