Communication error when using or_debug_proxy on ML501 by alonzo on Aug 5, 2011			alonzo Posts: 23 Joined: Jan 23, 2009 Last seen: Nov 14, 2017
Hi all, I tried to connect to the ML501 using or_debug_proxy and it is not working: ./or_debug_proxy -r 55555 Connecting to OR1k via USB debug cable Initialising USB JTAG interface JTAG ID = a188a928 Stalling OR1K CPU0 Communication error. Retrying Resetting or1k Resetting or1k Resetting or1k Stalling or1k or1k should be stalled I compiled successfully (I think) the bitstream from orpsocv2 and downloaded it to the board. I am using or_debug_proxy rev. 566 and orpsoc rev. 568 Any suggestions as to how to debug this? Thanks, Alonzo.

In the Makefile for or_debug_proxy uncomment the following line: [q]DBGCPPFLAGS=-DDEBUG_USB_DRVR_FUNCS=1 -DDEBUG_GDB=1 -DDEBUG_CMDS=1[/q] Do the or_debug_proxy's "make static" again, and try to run it and paste the output here (or put it in a text file and attach it if it's too long.) I also have a pre-built image for the ML501 if you would like to try that.

Hi Julios, Please find attached the file with the output of or_debug_proxy. It doesn't say much to me, I hope it says something to you. The pre-compiled bitstream might be a good idea. That way we might be able to discard the FPGA programming in this problem. Can you email it to me or put it somewhere to download it? By the way, I am not compiling the or_debug_proxy statically. I am using the dynamically linked executable. When I compile it statically or_debug_proxy generates a segmentation fault each time I run it. I am using ubuntu 10.10 (Maverick Meerkat), 64 bits.

Not sure what happened, I am trying again to post the attachment. Can you email me the bitstream please? Not sure what happened, I am trying again to post the attachment. Can you email me the bitstream please?

Hi all, I am still having the same problem. I tried a pre-compiled bitstream, and a different computer (32 bits instead of 64) and the communication problem persists. It looks like I can see the TAP controller, but I cannot talk to the processor. At this point any idea is welcome. Please help. Hi all, I am still having the same problem.

What debug cable are you using - an ORSoC USB JTAG cable? Also, the pre-built image available for download from the wiki here should have ORPmon embedded in it and it should come up at boot with a little console. Can you at least see that over the UART (you can just plug in a serial cable to the serial port on the board to see UART output, or hook up the debug cable, which also has UART lines)?

Hi, I am using the ORSoC USB JTAG cable. It looks like neither the serial port in the board nor the serial port in the debug cable produce anything. I set minicom to 115200 8N1 and nothing. To make sure, I hooked an oscilloscope to the TX lines and I didn't see anything after the bitstream is loaded (done pin goes high). I checked everything I can think of in the board. The clock chip seems to be programmed correctly ( the demo programs work fine ). Not sure what else could be wrong. Next thing I am thinking is to add a chipscope core to the code so I can monitor the internal signals and try to figure out what is wrong ... Alonzo. Hi, I am using the ORSoC USB JTAG cable.

Hi, I would like to share with you guys what I've done to "solve" this. I borrow another board from a friend. I followed the same procedure to program the FPGA, used the same file. In this new board I can finally talk to the processor: Connecting to OR1k via USB debug cable Initialising USB JTAG interface JTAG ID = a188a928 Stalling OR1K CPU0 Read npc = 000172bc ppc = 000172bc r1 = 000237d0 Waiting for gdb connection on localhost:55555 Press CTRL+c to exit. I've checked both boards, inch by inch, and all jumpers and switches are the same. I have no idea what is wrong in the first board. I know the board works because we've used it for other projects. But I don't know why it doesn't work for this specific project. Anyways, I guess this post will go away as an "unsolved" mystery. Hi, I would like to share with you guys what I've done to "solve" this. I borrow another board from a friend. I followed the same procedure to program the FPGA, used the same file. In this new board I can finally talk to the processor: Connecting to OR1k via USB debug cable Initialising USB JTAG interface JTAG ID = a188a928 Stalling OR1K CPU0 Read npc = 000172bc ppc = 000172bc r1 = 000237d0 Waiting for gdb connection on localhost:55555 Press CTRL+c to exit. I've checked both boards, inch by inch, and all jumpers and switches are the same. I have no idea what is wrong in the first board. I know the board works because we've used it for other projects. But I don't know why it doesn't work for this specific project. Anyways, I guess this post will go away as an "unsolved" mystery.

Hi, I won't close this one too early. I have the same issue on a XUPV5 board (identical to ML505 to ML506). I will also check another board, but nevertheless that seems dodgy to me.
