The article I shared does indicate that Cortex-M debugging on the Verdin i.MX 8M Plus can indeed be achieved using the Segger J-Link hardware.
If you are talking a bout A core debugging - as I said it possible but Toradex does not support it. We recommend to use software debuggers instead, check here for example . If you still need to use JTAG debugging for A cores Fill free to use NXP community , Stack overflow or any other resources.
