Dear Damjan,

I rewrite the hello.c file because I can't manage a bigger memory in the
ise (and I don't know why). So i have 1 kb onchip memory, and wrote a
program which write something to a concrate memory address. In the
gdb I watch the memory address before and after the program run, and
the program write the memory address, so the processor and the
memory are work. The problem is that when I push the c button in the
gdb, the gdb write continuing and I don't get back the gdb prompt
(gdb). It looks like it is in an endless loop. I try the original and rewrite
hello.c but the result was the same. Sometimes when I push ctrl c the
gdb is mend but sometimes it isn't and the jp1 proxy go wrong too. Do
you know what cause the problem exactly.

Thanks a lot!

i do not have any concrete information. so maybe you can trace
it a bit and send some findings to the list, maybe sombody will have
an idea.

Dear Matjaz, I think I solved the memory problem, the ISE can't give parameters to the memory module so I wrote it to the BLKMEMSP_V5_0 and it works properly. I can write data to memory addresses I think the or1200, debug unit, the cop matrix, and the onchip ram works properly. I use the hello.c file and put some REG32 function in the main function. The momory addresses where I put some data with the REG32 function are appear in the addresses, so the main function is run, but I can't see the hello word on my minicom window. I measured the fpga srx, stx legs with scope they are always logical one before the program run and after too. It seem the uart or the uart.h has a problem. When in the gdb I push the c button the gdb write continuing and it could quit with ctrl c, and after I restart the jp1 server it isn't write the same numbers the second column last two digits. I have to reload the Soc to the FPGA. Last time you write me send the error code, here it is the gdb error: [root@smart hello-uart]# or32-uclinux-gdb hello.or32 GNU gdb 5.0 Copyright 2000 Free Software Foundation, Inc.
