I've been having problems connecting to the CMSISDAP debugger interface, and after sifting through several threads I found this one:

ls102x CMSIS-DAP JTAG chain issue    

Wherein there was an issue with a custom board not working with version 0201 of CMSISDAP Firmware, but 0203 does.  The version of CMSISDAP Firmware that shipped with the TWR demo board (on the USB stick) is 0201.  I am having seemingly the same problem, but with the LS1021A_TWR board:

(bin) 25 % config cc cmsisdap
Identified CMSIS-DAP SERNUM: 20000201C5041E0238FAC1FA
Firmware version: 0201
0: CMSIS-DAP (cmsisdap) CC software ver. {0.4}
(bin) 26 % ccs::config_chain {ls1020a cmsisdap}

## this hangs for a while before printing the next message, LED2 blinking quickly 
LS1020A: Core not responding

I'm also seeking the latest version of the CMSIS-DAP firmware and found that this didn't work for me either. Do you have a different copy?

ufedor:

Thanks for your help, but that image doesn't appear to be working.  After deploying to the bootloader and reconnecting the USB, D2 doesn't come on and the device doesn't appear on any of the interfaces (CCS, COM port, devices and printers, etc.).  The output from CCS is as follows:

CodeWarrior Connection Server console display active (Tcl8.4.12 / Tk8.4.12)
Loading CCSAPI Tcl interface (C:/Freescale/CW4NET_v2017.03/Common/CCS/bin/ccstcl.dll)...

Are you working from the github project for the K20 to make this binary?
