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.
