How and Which CWSIS-DAP adapter i should use to program the LS1201A

I don't have the CodeWarrior TAP, and i see the CodeWarrior TAP studio can use CWSIS-DAP,

I want to know which adapter should i use to program the LS1201A

It looks like that the LS1021a is used.

The TWR-LS1021a board uses USB-to-UART bridge - MK20DX128VFM5. This bridge is used for CMSIS-DAP from MBED:

Use the following page for downloading CMSIS-DAP driver:

i donwload the driver and config the codewarrior to connect the board ls1201a and start debug and get the error:

启动1111-core0_RAM_LS1021ATWR_Download出错
CCSProtocolPlugin : Failed to correctly configure the JTAG chain

IN LS1201A, here are J12, J2 and J10,

J12 - connect to LS1021ASE7MQB's jtag

J2 - connect to MK20DX128VFM5's jtag

J10 - connect to LCMXO1200C-3FTN256C's jtag

if i want to use CWSIS-DAP to debug the board, which connectter should i use?

Use the J12 for connection to the LS1012a.

Look at the Section 8.2 of the CW_ARMv7_Targeting_Manual.pdf file.

RCW override is not supported with a CMSIS-DAP connection.

When using the CMSIS-DAP probe, it is recommended to verify operation parameters and RCW correctness before continuing. Failure to program a compatible RCW may result problem for connection using CMSIS-DAP

Check RCW on your board.
