ls102x CMSIS-DAP JTAG chain issue

Hi All,


I have ls1021atwr and custom board which is very close to ls1021atwr by design.

I can attach to ls1021atwr from CW via CMSIS-DAP with no errors,

but if I use the same way for connecting to custom board CW hungs at 82% point

for at about 3 min. I get "Failed to correctly configure the JTAG chain" message after.


I can see all JTAG signals (TDI,TDO,TMS,TCK,TRTS) on oscilloscope during connection progress.

It looks like there is no difference.


Can anyone point me how to figure out what is going wrong?


 Thank you.
