Subject: [openrisc] jp1 server
Dear Damjan, Thank you your quick anwser. I have read the hardware and software tutorial and followed the directions, but unfortunately the jp1 server couldn't communicate with the SoC. I read the the jp1.c file and found that in xilinx mode it isn't use the trst_pad_i, but on the dbg_top.v there is a trst signal. I put the trst signal to switch which is on the board and before I use the jp1 software push the reset button is it good method or not? The ISE write: the application could work up to 50MHz, so I just put the clk signal to the MEMEC board 24MHz signal. The WISHBONE_clk and the clk is the same in my SoC. I'm not use the ibufg modul (if I use the ISE write an error ngdbuild 466 ) and not use the CLKDLL. On the HW tutorial there is an instruction remove .genpc_stop_prefetch (genpc_stop_prefetch) the line from the or1200_cpu.v, the newest ORP there isn't a line like this .genpc_stop_prefetch (1'b0) is it good or I have to remove it? I measured the jtag module signals with an oscilloscope and sometimes the clk signal isn't go to the 3,3V peak just approximateli 1,7V is it a normal or my jtag module isn't work properly? Thank you your anwser!
