LPC 1788 Ethernet configuration

borhaderoshan — Thu, 22 Aug 2019 07:09:16 GMT

I am using LPC1788 conrtex M3 microcontroller and trying to configure its e ETHERNET port by using CMSIS RTOS2 RTX5.
I am able to run other drivers like UART , TIMERS , and GPIO's using RTOS2 RTX5.
But facing some issues to run ETHERNET.

microcontroller - LPC1788 M3
Phy IC - LAN8720
Driver - ETH MAC 0
Interface - RMII
IDE and Compiler - Keil microvision-5
software development suite - MDK-Plus
RTOS - RTOS2 RTX5 version 5.5.0

Please find attached c files and Configuration setting I have done in my project.

I am calling netInitialize(); function from main()
it returns me "netOK" that means Network Core initialized successfully

Then I am calling netTCP_GetSocket function and passing "tcp_cb_server" call back function as an argument it as below

tcp_sock = netTCP_GetSocket(tcp_cb_server);
if (tcp_soo itck > 0) {
netTCP_Listen(tcp_sock, 2000);
}

I am getting tcp_sock = 1,
I am checking status of the socket created "tcp_sock" using function
socket_status = netTCP_GetState(tcp_sock);
it returns me "netTCP_StateLISTEN"
means socket is listen mode.
but when I try to connect through Hyperterminal unable to established a connection
Please find attched code and configuration settings.
Please help on high priority

Hello Roshan,

Unfortunately, there is no information on our side regarding the implementarion of CMSIS RTOS2 RTX5 with our LPC MCUs.

However, we have an example you can take a reference from the LPCOpen library called lwip_tcpecho_sa using freertos. I highly recommend you to take a look at it.

You can download the LPCOpen library from the following link:

https://www.nxp.com/design/microcontrollers-developer-resources/lpcopen-libraries-and-examples/lpcopen-software-development-platform-lpc17xx:LPCOPEN-SOFTWARE-FOR-LPC17XX

Sorry for the inconvenience this may cause you.

Best regards,

Felipe
