I have noticed that the CMSIS-DAP firmware provided in this repository encounters difficulty in supporting SoC-600-based devices using JTAG.
The introduction of JTAG DP Protocol version 1 in SoC-600-based devices, utilizing separate OK and FAIL responses rather than a combined OK/FAIL response as in JTAG DP Protocol version 0, maybe the cause of the JTAG issues.
However, the CMSIS-DAP-based firmware still relies on the OK/FAIL response during JTAG transfer, as in this example - https://github.com/ARM-software/CMSIS-DAP/blob/main/Firmware/Source/JTAG_DP.c#L183.
Are there any plans to incorporate support for JTAG DP Protocol version 1?
I believe this could potentially be achieved through the extension of DAP_Connect or DAP_JTAG_Configure commands.
