Hello,
I'm working with a custom board that uses an external 12V supply for the VCC pin (gate driver supply) of STSPIN32g4. The VCC supply is interrupted by external circuitry whenever a fault is detected.
The problem I'm encoutering is that when the 12V is removed the firmware gets stuck by continuously calling the interupt "TIMx_BRK_M1_IRQHandler" in the file "stm32g4xx_mc_it.c" and no other code gets executed.
I tried to stop the timer calling this interrupt but without success.
The goal is to remove torque to the motor by hardware as if being connected to an enable/disable input.
Thank you in advance.
