Posted on January 03, 2018 at 16:05I've been some months working on a Firmware for STM32L476VG. I've made a second version of my PCB adding more hardware as 6 MOSFET controlled from MCU.
The problem is with the MOSFET controlled from PE10, as seen in the code below when I put the declarations and initialization which is correct or that�s what I think because I�ve been using same type of declarations and initializations in more projects, then the running/debug has strange behavior. It goes thru the code until it finds:
HAL_GPIO_Init(GPIOE, &GPIO_InitStruct);
Here sometimes jumps to memory position 0000 0000,
Other it gets stuck at startup_stm32l476xxx.s LoopForever(line 118) � here it gets because strange or unexpected ISR, I have to investigate more about this.
If I comment lines:
HAL_GPIO_WritePin(GPIOE,GPIO_PIN_10,
GPIO_PIN_RESET);
GPIO_InitStruct.
Pin
= GPIO_PIN_10;
GPIO_InitStruct.
Mode
= GPIO_MODE_OUTPUT_OD;
GPIO_InitStruct.
Pull
= GPIO_NOPULL;
GPIO_InitStruct.
Speed
=
GPIO_SPEED_LOW
;
HAL_GPIO_Init(GPIOE, &GPIO_InitStruct);
All runs perfect, except PE10

MX_GPIO_Init(

So, anybody has faound same strange behaviour?
