Posted on May 18, 2018 at 08:45Hi,
Please help me !!! I am new to Ethernet.
I have a costume board with STM32F765 controller and the PHY is KSZ8041TL(Microchip) with RMII mode.
Am generating the low level init code with the help of Cubemx. So for testing the hardware and for making the basic Ethernet communication working - I have two boards with me and i am writing raw data (with out using LwIP) from one board and receiving it other board - that's my plan.
In the cubemx Ethernet configuration i have selected 'user PHY' and by hardware we made the PHY address as 1. We use 50Mhz external clock as well for RMII mode. RX mode is 'Polling mode'.
My code stuck in ' MX_ETH_Init () - > HAL_ETH_Init () 'function.
code section below for your reference.
/* Wait until the auto-negotiation will be completed */
do
{
HAL_ETH_ReadPHYRegister(heth, PHY_BSR, &phyreg);
/* Check for the Timeout */
if((HAL_GetTick() - tickstart ) > ETH_TIMEOUT_AUTONEGO_COMPLETED)
{
/* In case of write timeout */
err = ETH_ERROR;
/* Config MAC and DMA */
ETH_MACDMAConfig(heth, err);
heth->State= HAL_ETH_STATE_READY;
/* Process Unlocked */
__HAL_UNLOCK(heth);
return HAL_TIMEOUT;
}
} while (((phyreg & PHY_AUTONEGO_COMPLETE) != PHY_AUTONEGO_COMPLETE));
If am dong something wrong or i am missing to set something? Please help me .
Thanks and Best Regards,
Vineeth
