FLASH_WaitForLastOperation CubeMx error

Hi

Schlenger.Thomas

Could you precise inwhich HAL library you have found the issue. So, we can verify it.

Hi Nesrine,

it is in 'stm32l4xx_hal_flash.c' and starts in line 638. i.e. if HAL_GetTick() returns 0xffff8000 and Timeout is 50000 then timeout will be 17232, so the next compare with GetTick will initiate a timeout...

I changed the repository in this way, which seems to work.

Thanks a lot for the very fine work on the very helpfull cubemx package.

HAL_StatusTypeDef FLASH_WaitForLastOperation(uint32_t Timeout)
{
 /* Wait for the FLASH operation to complete by polling on BUSY flag to be reset.
 Even if the FLASH operation fails, the BUSY flag will be reset and an error�?�?�?�?
 flag will be set */
 
/*
 uint32_t timeout = HAL_GetTick() + Timeout;
 while(__HAL_FLASH_GET_FLAG(FLASH_FLAG_BSY)) 
 { 
 if(Timeout != HAL_MAX_DELAY)
 {
 if(HAL_GetTick() >= timeout)
 {
 return HAL_TIMEOUT;
 }
 } 
 }
*/
 // change ths 2017
 uint32_t timeout = HAL_GetTick();
 while(__HAL_FLASH_GET_FLAG(FLASH_FLAG_BSY)) 
 { 
 if(Timeout != HAL_MAX_DELAY)
 {
 if(HAL_GetTick()-timeout >= Timeout)
 {
 return HAL_TIMEOUT;
 }
 }

I have similar problem. I am using STM32F303CBT6TR and I get HAL_ERROR at

https://github.com/zhivko/EclipseStm32/blob/master/Src/eeprom_flash.cpp#L156

I just copied source code from CubeMX example located at:

.\STM32Cube\Repository\STM32Cube_FW_F3_V1.7.0\Projects\STM32303C_EVAL\Examples\FLASH\FLASH_WriteProtection\Src\main.c

It seems I an getting error only in case of debugging code.

If I run it without debugger it seems it runs OK. What is the reason that I am getting HAL_ERROR

 ? Is it because of 

FLASH_WaitForLastOperation contains HAL_GetTick  that doesnt work OK while debugging ?
