Linux/PROCESSOR-SDK-AM335X: pthread debug

Aleksey Barboy

Part Number: PROCESSOR-SDK-AM335X

Tool/software: Linux

Hello,

I'm using our board made from am335x sdk kit, with ti-sdk-am335x-evm-05.05.00.00

I found out that I can't do phtread debug with gdb.

Some digging shows that gdb needs nonstriped version of pthread library

Do you know if it's true? and if yes how can I get it?

Thank you.

Thank you, Margarita,

Stackoverflow shows

(A) This frequently happen on Linux, especially on embedded targets. There are two common causes:

you are using glibc, and you have stripped libpthread.so.0
mismatch between libpthread.so.0 and libthread_db.so.1-

I think I have fists case because sdk target toolchain comes with striped libpthread.so.0

Now I'm not sure what do next?

Thank you, Aleksey.

I try to debug threads with gdbserver, but the problem is the same it would not show correctly threads .
