Hi Alex,

Finally I got my path adapter from segger. But after connecting I am getting the following errors. Any idea on how to fix this?

Sorry target config mentioned above gives this error:
openocd: src/jtag/core.c:343: jtag_checks: Assertion `jtag_trst == 0′ failed.

But this works:
target create $_TARGETNAME cortex_m -dap $_CHIPNAME.dap -ap-num 0

[mazidulalamParticipant]

Yes I have. This is my target in openocd config file:

set _TARGETNAME $_CHIPNAME.cpu
target create $_TARGETNAME rv32m1 -endian little -chain-position $_TARGETNAME

I have managed to establish connection with the board via cmsis-dap interface but cant flash program any code as halt command fails every time. As mentioned above cmsis-dap works with arm cores, I should be able to program on M0 and M4 cores of the board, right?
