[SOLVED] Send custom JTAG commands to unsupported micro

GMG · Jun 17th 2022, 1:15pm

Hi, is it possible to send/receive custom defined JTAG commands to a unsupported micro like PowerPC or Tricore? So using JLINK only as a transport hardware that implements TAP and keep the logic outside Segger software?

Best regards

Hi GMG,
Yes there is.

The most customizable and solid way would be to acquire and use the J-Link SDK.

But you could also use the J-Link Commander:

Thanks a lot, I think the JTAG Commander can be the right tool, I need only to test basic things no flash programming needed

The Commander is more a getting started / verification utility for supported cores.
What you are probably looking for is JTAGLoad:

It‘s part of the J-Link software package.
