SVD file in config, error during microcontroller initialization FDCAN->ARA being set

Type: Bug Report

Describe the bug

OS and Version: Ubuntu LTE
VS Code Version: 1.82.2
Extension Version: v1.4.6
Target Device: STM32H5
Other extensions you installed (and if the issue persists after disabling them): cortex-debug and C / CMake development tools.
A clear and concise description of what the bug is.

Just for future reader... I posted my original question here: https://github.com/Marus/cortex-debug/issues/931#issue-1900492186

I am configuring FDCAN on a STM32 H5 microcontroller.

I have the situation in which adding the following line:

"svdFile": "${workspaceRoot}/.vscode/STM32H573.svd",

and enabling the interrupts I have continuously the following error set:

immagine

I therefore disabled the interrupt again and while having the XPERIPHERALS windows active I checked in which line the error flag is set.

the flag is set as soon as the __HAL_RCC_FDCAN_CLK_ENABLE macro is called in the initialization code. The interrupt is then always asserted and the program does not proceed.

Seen that I am using openocd for connecting to the nucleo board, (openocd config generated by stm32cube) I loaded the elf file in stm32cube and debugged it from there. I can confirm that also enabling the corresponding XPERIPHERALS window of the stm32cube, the program executes normally. The error is not set.

this means:

same elf
same openocd config
different debugging gui

To Reproduce Steps to reproduce the behavior:

Configure FDCAN
In launch.json enable the SVD file loading
proceed to FDCAN initialization
step on __HAL_RCC_FDCAN_CLK_ENABLE macro
FDCAN ARA in FDCAN_IR is set
disabling the svd in launch.json fdcan initialize correctly and it works correctly

Expected behavior

to be able to debug my code while having a SVD file loaded
