I am new at using JTAG. Currently I have an NGX jtag. Do you have any recommendations on what software to use for investigating/accessing IMX6X CPU pins? I currently have a board right now and I wanted to know/check how the CPU pin works.
Which board are you using? About debug tool you can refer to iMX6 Quad JTAG Debug . The jatg is for debug chip. Here recommend you to run linux or android BSP on your board, in the BSP you can see the pin configue.
