Dear Everyone,
I'm using MCUXpresso for VScode and i managed to debug my project for IMXRT1176 EVKB with all panes (peripheral, variables ... ) working. I think it uses MCU-LinkServer under the hood so i wanted to use it as well to create more lightweight setup.
I tried to follow this tutorial:
https://mcuoneclipse.com/2023/11/27/mcu-link-with-cortex-debug-and-linkserver/
I got my SVD file from here:
https://github.com/nxp-mcuxpresso/mcux-soc-svd/blob/main/MIMXRT1176/MIMXRT1176_cm7.xml
Tasks.json:
{
"version": "2.0.0",
"tasks": [
{
"type": "shell",
"label": "start LinkServer",
"command": "LinkServer gdbserver --keep-alive MIMXRT1176:MIMXRT1170-EVKB -c all",
"options": {
"cwd": "${workspaceFolder}"
},
"group": {
"kind": "build",
"isDefault": false
}
}
]
}
Launch.json:
{
"configurations": [
{
"name": "Cortex Debug Launch cm7",
"type": "cortex-debug",
"request": "launch",
"servertype": "external",
"gdbTarget": "localhost:3333",
"cwd": "${workspaceFolder}",
"executable": "cm7/flexspi_nor_debug/imxrt1176_CM7.elf",
"runToEntryPoint": "main",
"preLaunchCommands": [

],
"postLaunchCommands": [
"load"
],
"rtos": "FreeRTOS",
"svdFile": "${workspaceFolder}/MIMXRT1176_cm7.xml"
}
]
}
After i setup the gdb server via start linkserver task, i can connect to the device, i can perform steps and place breakpoints. But the peripheral pane is not working, every time i perform a step i get error in VSCode and error message in GDB:
Temporary breakpoint 2, main () at D:\projects\main_master.c:316 316 BOARD_ConfigMPU();

Internal error: Failed to update peripheral LPI2C6 after memory reads
And in VS-Code there is a pop-up:
Read memory error: Unable to read memory. (from data-read-memory-bytes "0x40c38110" 28)
Does anyone know what can i do to fix it? Or what is the root of the issue?
I'm not in need 100% for cortex-debug i used it as my default, if there is other debugger that works i can switch to it. If there is no solution i will just stick with nxp for vscode extension.
