Posted on April 25, 2017 at 10:16Hi All,
I am fighting with F429nucleo and ethernet interface. The example of firmware works well (lwip webserver).
There is a pin PG2 RMII_RXERR which I cannot configure with CubeMX.
On CubeMX PG2 cannot set to ethernet, but the firmware example does it set to ethernet alternate mode:
GPIO_InitStructure.Speed = GPIO_SPEED_HIGH;
GPIO_InitStructure.Mode = GPIO_MODE_AF_PP;
GPIO_InitStructure.Pull = GPIO_NOPULL;
GPIO_InitStructure.Alternate = GPIO_AF11_ETH;
/* Configure PG2, PG11, PG13 and PG14 */
GPIO_InitStructure.Pin = GPIO_PIN_2 | GPIO_PIN_11 | GPIO_PIN_13;
HAL_GPIO_Init(GPIOG, &GPIO_InitStructure);
Another problem is setting clocks. Example settings:
@brief System Clock Configuration
* The system Clock is configured as follow :
* System Clock source = PLL (HSE)
* SYSCLK(Hz) = 180000000
* HCLK(Hz) = 180000000
* AHB Prescaler = 1
* APB1 Prescaler = 4
* APB2 Prescaler = 2
* HSE Frequency(Hz) = 8000000
* PLL_M = 8
* PLL_N = 360
* PLL_P = 2
* PLL_Q = 7
When I set PLL_Q to 7, it has an error, at least 8 is acceptable, and the output clock will be 45Mhz instead of 48Mhz.
And example said:
* VDD(V) = 3.3
* Main regulator output voltage = Scale1 mode
* Flash Latency(WS) = 5
Where can I set these properties in CubeMX?
thx Zamek
