Beaglebone Black : IR capture error #38

Closed r00tb3 closed 5 years ago

r00tb3 commented 5 years ago

I'm trying to JTAG BBB using J-Link adapter and I end up facing the following error:

I'm unable to halt the processor after opening up a telent session nor able to do anything else.

After openeing a telenet session.

   Trying 127.0.0.1...
   Connected to localhost.
   Escape character is '^]'.
   Open On-Chip Debugger
   > halt
   Target not examined yet

Where am I going wrong?

I don't know.

Did you try the same sequence of commands with an OpenOCD build from the master and it works?

r00tb3 commented 5 years ago

@ilg-ul No but as you can see from above I'm using the 2018-10-20 version i think this will be stable.

ilg-ul commented 5 years ago

the 2018-10-20 version i think this will be stable

negative. those versions included some RISC-V code which affected the other targets.

not to mention there is no such thing as a stable OpenOCD version.

try the latest release.

anyway, before reporting problems here be sure they are specific to the GNU MCU Eclipse distribution, which means a similar version built from the master sources works.

if the problem also occurs in the master, please report it to https://sourceforge.net/p/openocd/tickets/

r00tb3 commented 5 years ago

@ilg-ul Okay!! I'll try the master version and the latest release let you know soon.

Thanks for the response.

I tried as you said git cloned the master branch built it still gives me the same error.

I don't know where I'm going wrong.

sorry, I don't use openocd, and I don't have experience with the BB. :-(
