Hi again, Finally I could continue my tests on zc706 and the second processor start.
I could add two breakpoints one at _CPU_SMP_Start_processor (0x0041e7b0) and other at _Per_CPU_State_wait_for_non_initial_state (0x0041e7d4) at the end of the function _CPU_SMP_Start_processor. Execution stops and continues in both breakpoints, but I still need to need to start the second processor from xsdb. I attach you a capture of the objdump done at the end of the mail. > Yes I believe so. I tested the m2003 version. Can you share me the compilation flags you use for your tests executables? And sorry for this answer, but where can I find the m2003 version? Is it a git tag, branch.. ? I don't see anything similar on GitHub repos. > I wonder if xsdb is doing something.

I tested this on custom hardware using the zc706 BSP that is booting from QSPI. > I remember two years ago I started two processors using SMP on a zedboard > without starting second core using xsdb. I wonder if xsdb is doing something. Are you able to set a break point in the code I provided to the link to in zynq_start_bspsmp.c that starts the second process?
