Hi,

I stumbled upon an issue running the code from the STM32F4_HAL_ETH_RTOS_TCPCLIENT project.
I am using IAR ARM as a compiler and stm32f417VG (as stated in the title).
The code builds and I can start it but after the call netconn_connect(conn, &server_addr, SERVER_PORT); in freertos.c
err = 0xF3 - ERR_ABRT and I am uncertain why..

The only change I have made to the code are the pin setup for the eth circuit DP88 which I am using along with the stm32f4 which consists of :
/* Configure MCO (PG13) */
GPIO_InitStructure.Pin = GPIO_PIN_13;
GPIO_InitStructure.Speed = GPIO_SPEED_FREQ_VERY_HIGH;
GPIO_InitStructure.Mode = GPIO_MODE_AF_PP;
GPIO_InitStructure.Pull = GPIO_NOPULL;
GPIO_InitStructure.Alternate = GPIO_AF11_ETH;
HAL_GPIO_Init(GPIOG, &GPIO_InitStructure);

/* Ethernet pins configuration ************************************************/

/* Configure PA1, PA2 and PA7 */
GPIO_InitStructure.Pin = GPIO_PIN_1 | GPIO_PIN_2 | GPIO_PIN_7;
GPIO_InitStructure.Alternate = GPIO_AF11_ETH;  
HAL_GPIO_Init(GPIOA, &GPIO_InitStructure);

/* Configure PB11, PB12 and PB13 */
GPIO_InitStructure.Pin = GPIO_PIN_11 | GPIO_PIN_12 | GPIO_PIN_13;
GPIO_InitStructure.Alternate = GPIO_AF11_ETH;  
HAL_GPIO_Init(GPIOB, &GPIO_InitStructure);

/* Configure PC1, PC4 and PC5 */
GPIO_InitStructure.Pin = GPIO_PIN_1 | GPIO_PIN_4 | GPIO_PIN_5;
GPIO_InitStructure.Alternate = GPIO_AF11_ETH;  
HAL_GPIO_Init(GPIOC, &GPIO_InitStructure);

/* Configure ETH_RESET_N (PE15) */
GPIO_InitStructure.Pin = GPIO_PIN_15;
GPIO_InitStructure.Speed = GPIO_SPEED_FREQ_LOW;
GPIO_InitStructure.Mode = GPIO_MODE_OUTPUT_PP;
GPIO_InitStructure.Pull = GPIO_NOPULL;  
HAL_GPIO_Init(GPIOE, &GPIO_InitStructure);
/* Initiate to HIGH state (inactive) */
HAL_GPIO_WritePin(GPIOE, GPIO_PIN_15, GPIO_PIN_SET); `

Do you have any ideas why the net_connect function returns 0xF3 - ERR_ABRT?

When running this on a Windows platform the #define LWIP_RAND() ((u32_t)rand()) dod not work and I had to use HAL_RNG_GetRandomNumber.

But when it did run the Data console showed this - can you try it and see if you get the same?

Thanks

Andy.

error on mbedtls...

mbedtls_ssl_setup() allocs memory but you don't free it up in your example loop with mbedtls_ssl_free()

The simple fix I did was move the "*1. Start the connection" including the 'While' to just before the " * 4. Handshake"

See attached file.
