Cannot get Ethernet working on STM32H745 DISCOVERY BOARD using AZURE RTOS (THREADX) and NETX

[HKapo.1]

Hello All,

I am trying to create a simple project for transmitting some UDP packet but it is not working.

I have used STM32cube to generate the project with below configuration:

Change Timebase to TIM6

 

Setup the MPU and enable D and I Cache

 

Selected below middleware

Changed the linker script

 .tcp_sec (NOLOAD) : {
 
 . = ABSOLUTE(0x30040000);
 *(.RxDecripSection)
 
 . = ABSOLUTE(0x30040060);
 *(.TxDecripSection)
 
 } >RAM_D2 AT> FLASH
 
 
.nx_data 0x30040200 (NOLOAD):
 {
 *(.NetXPoolSection)
 
 } >RAM_D2 AT >FLASH 

   Added below code to app_netx_duo.c

 /* Create the main NX_IP instance */
 IpAddress = IP_ADDRESS(10, 10, 1, 56);
 ret = nx_ip_create(&IpInstance, "Main Ip instance", IpAddress, 0xFFFFFF00UL, &AppPool, nx_stm32_eth_driver,
 pointer, 2 * DEFAULT_MEMORY_SIZE, DEFAULT_PRIORITY);
 
 if (ret != NX_SUCCESS)
 {
 return NX_NOT_ENABLED;
 }
 
 /* Allocate the memory for ARP */
 if (tx_byte_allocate(byte_pool, (VOID **) &pointer, DEFAULT_MEMORY_SIZE, TX_NO_WAIT) != TX_SUCCESS)
 {
 return TX_POOL_ERROR;
 }
 
 /* Enable the ARP protocol and provide the ARP cache size for the IP instance */
 ret = nx_arp_enable(&IpInstance, (VOID *)pointer, DEFAULT_MEMORY_SIZE);
 
 if (ret != NX_SUCCESS)
 {
 return NX_NOT_ENABLED;
 }
 
 /* Enable the ICMP */
 ret = nx_icmp_enable(&IpInstance);
 
 if (ret != NX_SUCCESS)
 {
 return NX_NOT_ENABLED;
 }
//#ifdef NEVER
 /* Enable the UDP protocol required for DHCP communication */
 ret = nx_udp_enable(&IpInstance);
 
 /* Allocate the memory for main thread */
 if (tx_byte_allocate(byte_pool, (VOID **) &pointer,2 * DEFAULT_MEMORY_SIZE, TX_NO_WAIT) != TX_SUCCESS)
 {
 return TX_POOL_ERROR;
 }
 
 
 /* Allocate the memory for UDP client thread */
 if (tx_byte_allocate(byte_pool, (VOID **) &pointer,2 * DEFAULT_MEMORY_SIZE, TX_NO_WAIT) != TX_SUCCESS)
 {
 return TX_POOL_ERROR;
 }
 /* create the UDP client thread */
 ret = tx_thread_create(&AppUDPThread, "App UDP Thread", App_UDP_Thread_Entry, 0, pointer, 2 * DEFAULT_MEMORY_SIZE,
 DEFAULT_PRIORITY, DEFAULT_PRIORITY, TX_NO_TIME_SLICE, TX_AUTO_START);
 
 if (ret != TX_SUCCESS)
 {
 return NX_NOT_ENABLED;
 }

I have created a static IP address rather than dynamic IP address. Also changed my PC IP Address similarly.

If I try using freertos and LWIP then it all works suggesting that link to board and PC are fine.

Can you please suggest if I am missing anything.

Kind Regards

Hello @Community member​ 

Could you, please, provide the code for the task that handles the UDP communication?

Thanks in advance.

BeST Regards,
