Hi Hoseong,

Did you update the SW in 2 MCUs through the daisy-chain? You can use the same way to connect JTAG emulator to the target MCU, then debug the code running in the target MCU.

I set up ccxml like this.

And there's no problem at Test Connection.

I think these are the reason for daisy-chain connected.

Checking Test Connection, i clicked debug button.

I found Two daisy-chained MCU.

but secondary MCU couldn't see anything. just 0x6466

it seems software didn't updated on secondary MCU.

Do you have any document about daisy chain software?

I did not use JTAG daisy-chain before, and I don't have example.
