[U-Boot-Users] still having issues with timer exception

hello, the subject line sums it all... There's no way I can get the timer working properly. Again, this is an unsupported board yet with a ppc405 core. I am using a debugger from windriver. The pit register remains with the value 0 although the tcr is set to 04400000 (reload) and the instruction mtpit(61a80) is called... Oh and btw, I took the walnut board as a model to port u-boot on my board and there's something I don't understand quite well in the flash.c file: function flash_erase. Why are interrupts disabled? And how can the wait_for_DQ7 function called by flash_erase could possibly work with disabled interrupts (how could the timeout be reached?)?

regards,
