Hello, I'm trying to get vanilla 2.6.13.1 running on an EP8248 board without much success. I created my own platform files and have the kernel booting, but the execution is permanently stuck in the cpm_uart_console_write() function in the first while ((bdp->cbd_sc & BD_SC_READY) != 0) statement.
I don't have any COP debugger for this processor family, so the only debugging aid is the two leds onboard... It's clear that the buffer descriptor is not in sync with the CPM, but I have no clue what the address of the buffer descriptor is. It seems this code is rather new, and I'm wondering if any of you have some patches that are not in the mainline kernel yet. Has anyone tested this with a 8248 processor? If so, could you please send your .config to me in case I made some errors in the platform definition.
