Try to run below commands from XSCT console. they will list the targets(jtag connection is ok)
if not listed then check
Are INIT_B and PS_ERROR_OUT are in RED?
If yes you might need to read the PMU error status registers(0xFFD80530 and 0xFFD80540)
Also try reading 0xFFD80528 to check the CSU BootROM error code why it is not up.

Thanks for your quick response!
I am able to "connect" and "target".
Once I am connected and target the a53 processor it is in reset so i cannot query these status registers.
"Memory read error at 0xFFD80530. APU L2 cache is held in reset"
What I can do is load a pmufw.elf and fsbl.elf and run those and then i can query using mwr 0xFFD80530/40/28
All three registers give me a 0 in this case.
The registers also give a 0 when run from the SD card or QSPI.
Once thing in addition i can say is that when trying to run a simple "hello UART" program, the psu_init command run in xsdb, hangs.
I read somewhere that is could be caused by a DDR misconfiguration but i do not know how to solve this/ determine if this is the problem.
