Im new into embedded.

I understand little of the response OpenOCD gives me.

Please point me into the right direction…

It seems to partially work since i can get some flash bank information (using telnet)

If that’s your config then it’s worthless.

Use STANDARD config files:

openocd -f interface/arm-usb-ocd.cfg -f target/lpc2103.cfg

And replace the wrong value of CPUTAPID in lpc2103 with 0x4f1f0f0f, and modify the clock to your value.

4/3!!

Works all fine with 0x4f1f0f0f where did you get this value from, if i may ask?

The OpenOCD installation i got doesn’t contain no target lpc2103.cfg

file, did copy most from posts i found.

Thanks for your help.

If the rest of the setup is OK, OpenOCD will display the value it found. You had to had something else messed up too - not just that value.

Indeed 0.1.0 release didn't have that file... Here you can get the "official" lpc2103.cfg file - it works - just adjust the core clock at the end.
