BUG with STM32L4-FW Version 1.5.1 and Nucleo-L476RG

The code generated by CubeMX (V. 4.16.1 and FW L4 1.5.1) does not work. The ErrorHandler() function is called by MX_USART2_UART_Init(). If I comment out this function and have an simple

HAL_GPIO_TogglePin(LD2_GPIO_Port, LD2_Pin);

HAL_Delay(1000);

in the main loop, the MCU gets stuck in HAL_Delay(). So this seams to be an issue with the SysTick System!

System used:

SystemWorkbench 1.10.... under Linux (Kubuntu 15.10).

Does this work under Windows? Anyone?

Hi wwmv,

Is it possible to check the error flags when debugging?

I am not sure that the ErrorHandler() code is generated by CubeMX. It seems to be added by your self.

Hello,

the ErrorHandler is generated by CubeMX.

Anyway, version 4.17 of CubeMX with the firmware update STM32L4 1.5.2 fixes the problem. (same setup/config, just migrated + code regeneration)
