HAL_DCMI_Stop timeout infinite loop

[frackers]

Posted on January 16, 2018 at 22:29

STM32Cube_FW_F4_V1.18.0 module stm32f4xx_hal_dcmi.c has a bug in HAL_DCMI_Stop such that when the 'count' variable is decremented to zero (to indicate a timeout), the loop continues.

I reckon there should be a 'break;' after the line

status = HAL_TIMEOUT;

Discovered after I lost vsync from a camera, tried to stop it and an hour later was still waiting!!

Just checked the F7 DCMI HAL code and that is OK.
