Hi,
I'm writting a console driver for an embedded system for which the hardware isn't quite ready yet. As a result I'm building on a PC with a quickly hacked up proc interface so I can test the logic before the final hardware.
On loading the module my code does the following:
take_over_console(&sh_con, MAX_NR_CONSOLES - 1, MAX_NR_CONSOLES - 1, 1);
Which I understand should associate my new console driver with the last system console (63 in this case). Then to test the console output I do:
echo "this is a test string" > /dev/vc/63
However my dmesg output shows no sign of any of the console functions being called to write data, although the module itself has loaded succesfully and run the take_over_console code.
Obviously I'm mis-understanding how the console should be accessed but I'm stuck looking for any pointers. I've been looking thorugh the newport_con.c driver for pointers but so far I've not seen any extra magic that I'm missing. Can anyone point me in the right direction/offer some tips?
