I have an STM32H742VGT based project with ethernet connection (LAN8742AI-CZ phy ) the problem is that I get HAL_ERROR when the HAL_StatusTypeDef HAL_ETH_Transmit(ETH_HandleTypeDef *heth, ETH_TxPacketConfig *pTxConfig, uint32_t Timeout)
When the HAL_ETH_Transmit is called by the driver it seems the code below (part of HAL_ETH_Transmit ) times out as the DMA TX complete callback are not called. I've followed the STM32H743 example but I guess STM32H742 memory map is a bit different than H743. Does anyone tries Ethernet on STM32H742 ?
Thanks
The timeout error
while((dmatxdesc->DESC3 & ETH_DMATXNDESCWBF_OWN) != (uint32_t)RESET)
{
if((heth->Instance->DMACSR & ETH_DMACSR_FBE) != (uint32_t)RESET)
{
heth->ErrorCode |= HAL_ETH_ERROR_DMA;
heth->DMAErrorCode = heth->Instance->DMACSR;
/* Set ETH HAL State to Ready */
heth->gState = HAL_ETH_STATE_ERROR;
/* Return function status */
return HAL_ERROR;
}
/* Check for the Timeout */
if(Timeout != HAL_MAX_DELAY)
{
if(((HAL_GetTick() - tickstart ) > Timeout) || (Timeout == 0U))
{
heth->ErrorCode |= HAL_ETH_ERROR_TIMEOUT;
heth->gState = HAL_ETH_STATE_ERROR;
return HAL_ERROR;
}
}
}
