MCU : CYW43907 (SB-WBM-N07P1_pEVB)

DBG : J-Link

JTAG : JTAG

Clock : 4MHz

CYW43907 JTAG for the first time with the device, there is the same error as the picture below.

JTAG first changed to SWD later and changed to JTAG,

I tried Clock and tried changing from 4M to 1000K.

It is the same symptom.

J-Link Command, and OZone are in the same state.

Could you tell me why?

I got cause and answer in a totally different direction.

I did not know the answer here,

It does not disappoint, however.

But FAE and agency that support me think there is a problem.

This will end my question.
