Ok. So if I understood properly, do_wait_for_fifo goes into timeout while do_wait_for_idle not. I think we still have some problem reading registers here as this makes no sense. Although on the first time the computer hanged didn't it? With the DMA appearently we are also having problems with do_wait_for_idle there... Can it be that we have timeouts too small? > I have tried this without the changes (listed below) suggested by José. Good. This means that the readl/writel macros are functional, although they don't fully solve our problems. José Fonseca _______________________________________________________________ Have big pipes?
