RT1180 Debugging not working

dogo · ‎02-12-2025

Hi together,

I currently have issues debugging my MIMXRT1180-EVK board using Zephyr RTOS in VSCode. Neither the MCU Link nor the JLink is working properly but with different problems.

MCULink:

Using the MCULink (and Linkserver run by west as GDB Server), I cannot access several address regions (e.g. all peripheral addresses 0x40000000/0x50000000 and external RAM at 0x14000000). VSCode and CortexDebug extension are giving me error messages like the following (trying to access CCM registers):

-data-read-memory-bytes "0x44452200" 52
error,msg="Unable to read memory."

Everything else (flashing, halting, breakpoints, reset) is working as expected.

When debugging a sample application in MCUXpresso IDE everything (also peripheral register readout) is working fine.

JLink:

When trying to choose JLink as a runner for west, I am able to attach to a running application (west attach or via the CortexDebug VSCode-Extension) and can access all relevant addresses there (peripheral register addresses in particular) without any issues. When trying to reset, nothing happens. The application seems to continue to run normally without a reset (no breakpoints at start are reached).

When trying to launch a debug session (west debug/west debugserver or via the CortexDebug VSCode-Extension), the application does not start. The JLinkScript file is the one provided by NXP. The JLink GDB server gives the following output:

Also, when trying to launch a debug session from within MCUXpressoIDE, I can see a similar behavior.

I'm looking forward for any help available.

Hi @dogo

As the i.MX RT1180 is still in preproduction, I'm afraid we do not have public information available for this device. I highly advice you contact your NXP representative that provided you with this i.MX RT device for more information about the debugging issues with VSCode.

BR,
Edwin.
