Subject: [openrisc] how to run hello world in on-chip ram?

hi, charlie yang:
now,i also do the same thing as you for "hello world" appearing on my
dev_board(cycloneII),and now i deal with hardware(or1200 uart debud
onchip_ram) according to hardware toturial,but some error coming!do you know
how i do ?
quenstions as follows:
1:according to the author ,adjust"or1200_pc.v",but there is no this file in
source files~~~
2:on_chip_ram,how do i do ?
3:when compiling,erros....i dont resolve...please help me ,,,i am real real
need it ...
thank you advanced!!!!!
can you give me some advise?
