Hi,
In
static HAL_StatusTypeDef CRYP_TDES_Process(CRYP_HandleTypeDef *hcryp, uint32_t Timeout)
{
uint32_t temp; /* Temporary CrypOutBuff */
uint16_t incount; /* Temporary CrypInCount Value */
uint16_t outcount; /* Temporary CrypOutCount Value */
/* Enable CRYP */
__HAL_CRYP_ENABLE(hcryp);
/*Temporary CrypOutCount Value*/
outcount = hcryp->CrypOutCount;
/*Start processing*/
while((hcryp->CrypInCount < (hcryp->Size/4U)) && (outcount < (hcryp->Size/4U)))
{
/* Temporary CrypInCount Value */
incount = hcryp->CrypInCount;
/* Write plain data and get cipher data */
if(((hcryp->Instance->SR & CRYP_FLAG_IFNF ) != 0x0U) && (incount < (hcryp->Size/4U)))
{
/* Write the input block in the IN FIFO */
hcryp->Instance->DIN = *(uint32_t *)(hcryp->pCrypInBuffPtr + hcryp->CrypInCount );
hcryp->CrypInCount++;
hcryp->Instance->DIN = *(uint32_t *)(hcryp->pCrypInBuffPtr + hcryp->CrypInCount );
hcryp->CrypInCount++;
}
/* Wait for OFNE flag to be raised */
if(CRYP_WaitOnOFNEFlag(hcryp, Timeout) != HAL_OK)
{
/* Disable the CRYP peripheral clock */
__HAL_CRYP_DISABLE(hcryp);
/* Change state & errorCode*/
hcryp->ErrorCode |= HAL_CRYP_ERROR_TIMEOUT;
hcryp->State = HAL_CRYP_STATE_READY;
/* Process unlocked */
__HAL_UNLOCK(hcryp);
#if (USE_HAL_CRYP_REGISTER_CALLBACKS == 1)
/*Call registered error callback*/
hcryp->ErrorCallback(hcryp);
#else
/*Call legacy weak error callback*/
HAL_CRYP_ErrorCallback(hcryp);
#endif /* USE_HAL_CRYP_REGISTER_CALLBACKS */
}
...
if(CRYP_WaitOnOFNEFlag(hcryp, Timeout) != HAL_OK) does not return HAL_OK
Crypt is disabled but function does not return so function may never return.
