Posted on November 03, 2017 at 08:24Hello .,
I am working on STM32 MCU in our custom board, In this I am facing some issues related to Ethernet interface.
I manage to generate Ethernet code using STM cube MX,(Using in RMII), The code is working but not reliably working,
When I make ping from PC it works 3 time out of 5 iteration. It works for some time . I don't find any solution for this problem.
MCU : Running at 216Mhz
Ethernet configuration I am using: : 100Mbps,Full duplex mode, And I have not enabled Ethernet global interrupt(NVIC setting) , Does this configuration make any problem.
I had changed the MCU running frequency to 108 mhz then also i'am facing the same problem
I have made some changes in code to make ping work :
int main(void)
{
HAL_Init();
SystemClock_Config();
/* Initialize all configured peripherals */
MX_GPIO_Init();
MX_LWIP_Init();
while (1)
{
MX_LWIP_Process();
}
/* USER CODE END 3 */
}
If I add MX_LWIP_Process() function in while loop then only the ping is working (That is also for some time not every time).
Can anyone suggest me to resolve this issue.
