OpenOCD JTAG / Re: Problem using BusPirate and OpenOCD
Yes, it ends like this:

Code: [Select]
Debug: 212 34 buspirate.c:985 buspirate_print_buffer(): 31

OpenOCD JTAG / Re: Problem using BusPirate and OpenOCD
ian: I am building the source off SVN.  I tried with both values of 115200 and 1000000.  Neither works.  I then installed openocd 0.3.1 via apt-get, but same result.

I then tried flashing the buspirate with the firmware robots linked to.  The buspirate then identifies itself as:

Code: [Select]
Bus Pirate v3b
Firmware v6.0RC (r572)  Bootloader v4.4
DEVID:0x044F REVID:0x3046 (24FJ64GA002 B8)
http://dangerousprototypes.com

However it seems to behave exactly the same, the 06 is followed by another BBIO:

Code: [Select]
Debug: 172 34 buspirate.c:985 buspirate_print_buffer(): 42 42 49 4f
Debug: 173 34 buspirate.c:949 buspirate_serial_read(): should have read = 1 actual size = 1
Debug: 174 34 buspirate.c:985 buspirate_print_buffer(): 31
Debug: 175 34 buspirate.c:917 buspirate_serial_write(): size = 1 ret = 1
Debug: 176 34 buspirate.c:985 buspirate_print_buffer(): 06
Debug: 177 34 buspirate.c:949 buspirate_serial_read(): should have read = 4 actual size = 4

OpenOCD JTAG / Problem using BusPirate and OpenOCD
After spending a few hours trying to get OpenOCD 0.5.0 (linux) talk to Bus Pirate I had to resign.  I am out of ideas.

First hurdle was: OpenOCD needs a "configure --enable-buspirate" in order for it to even compile support for Bus pirate.  Took me a while to figure this out.  The error message when running openocd is not very clear.

Second hurdle: There doesn't seem to be any OpenOCD support in latest version 5.10 of the Bus pirate firmware.  I eventually figured that out by reading this forum.  I proceeded to install version 5.8.

Third hurdle which I haven't yet been able to pass is related to communication.  I would like to know if anyone knows whether the log below indicates a problem between Bus pirate and OCD or is it from the Bus pirate to the target device?  Any hints or ideas appreciated.
