Guys,

I tried to test blinking LED using RTOS and cubemx, but can't make it until now ? what do I miss here ? Please have a look on the main.c .. Thanks for reading and giving a clues

Posted on April 29, 2015 at 09:46Reading your code I suggest, if you want toggling leds, to first remove or comment all your USB and FATFS stuff.Then remove or comment this line:StartDefaultTask(0);and use

osDelay() 

instead of 

HAL_Delay() in 

StartDefaultTask function.

Cheers

it worked already on toggling LED, but if I put ethernet, it's not blinking anymore,

Is there a conflict between Ethernet and GPIOE on STM32F107 ? Thanks

Sorry, but you must explain better your question. You did not mention about ethernet issues.

This is a different question 🙂So, first it's important to tell us what ethernet library and what PHY chip you use. From code you posted I see that MII protocol was choosen, right? Have you checked the hardware connections with PHY chip? Or do you have an evaluation board?

Cheers

I'm using my own board, and I haven't put any PHY yet, only for testing first,

I tried to use FreeRTOS,GPIO,Eth,USB and FatFS, but by the time I initialize Eth, GPIO no longer responding to my command for flipping LED.... Any ideas ? cheers...

I strongly suggest you using an evaluation board or discovery lines first, just to avoid any hardware issues, and I assume that you choose a board with a chip that support MII or RMII protocols (eg. STM32F407). A common PHY chip, used even in STM32 HAL, is DP83848: without it ethernet can not work.

Regards

Here's the code, if I commented out MX_eth_init, it's blinking, but if I initialize ethernet,

my LED only ON, not blinking... Why ?

int main(void)
{
/* USER CODE BEGIN 1 */
/* USER CODE END 1 */
/* MCU Configuration----------------------------------------------------------*/
/* Reset of all peripherals, Initializes the Flash interface and the Systick. */
HAL_Init();
/* Configure the system clock */
SystemClock_Config();
/* Initialize all configured peripherals */
MX_GPIO_Init();
MX_ETH_Init();
MX_USART2_Init();
/* USER CODE BEGIN 2 */
/* USER CODE END 2 */
/* Infinite loop */
/* USER CODE BEGIN WHILE */
while (1)
{
/* USER CODE END WHILE */
HAL_GPIO_TogglePin(GPIOE, GPIO_PIN_5 );
HAL_Delay(150);
HAL_GPIO_TogglePin(GPIOE, GPIO_PIN_6 );
/* USER CODE BEGIN 3 */
}
/* USER CODE END 3 */
}

Posted on May 04, 2015 at 11:18 CubeMX doesn't complain at all? After you added the Ethernet in. Ethernet uses one of the timers, probably your GPIO?

Posted on May 04, 2015 at 11:33

No it doesn't complain, which timer is being used by ethernet ? is it related with PORTE ?PE5 and PE6 ? thanks
