How can I perform JTAG debugging on the M7 core using a custom board with the AXON-IMX8M-PLUS?
I was able to perform JTAG debugging on the M-core of the i.MX 8M Plus EVK by following the tutorial below.
Debugging a custom board using the same method causes the i.MX to reset due to the JTAG TRST signal, preventing debugging from starting.
The JTAG circuit layout for the custom board is identical to that of the AXON-WIZARD-IMX8M-PLUS.
Why does a reset occur on the custom board but not on the evaluation board?
yocto: imx-6.6.52-2.2.0.xml
build option: imx-image-full
IDE: VSCode, mcuxpresso
debugger: jlink base
Resolved.
I'm embarrassed to say, but the JTAG pin configuration was incorrect.
Hi,
For the EVK board, we recommend to refer this AN, so you can also refer this AN.
