Subject: [openrisc] problem with running "hello uart" in v2pro
Hello,everybady.
I'm new here.
For the last few weeks I try to run the "hello uart" program in v2pro. I
built a program using the openrisc-HW-tutorial-Xilinx and
openrisc-SW-tutorial.
Then I tryed to run the program
download the .bit file
run jtag
-cd ... //location of jtag
-./jp1 xpc3 9999
run gdb
-cd ... //location of hello-uart
-or32-uclinux-gdb hello.or32
-target jtag jtag://localhost:9999
-load
-set $pc=0x100
-run
And there came the problem, the openrisc CPU didn't send control signal to
URAT union.
In the hello.or32 file, I found the reset.S instruction in 2100h and the
uart_init instruction in 4000h.
By using the JTAG ,I get the instruction which I have just download from the
ram. But I couldn't find the reset.S instruction which supposed to begin at
0x100 any where.And the uart_init instruction which is supposed to begin
after address 0x100 is founded in 0x00.
So I restart the system,set the PC 0x00,run the program. And it doesn't work
either.
Is there anyone met this problem before.Do you think there is something
wrong with my tool chain?
Because the tutorial I use is too old , I had to do something different from
what it tells.I downloaded the gdb5.3.patch from the
http://www.eecg.utoronto.ca/~jarvin/or32/gdb-5.3.patch.bz2.
Thanks a lot!
