RM57L843: Ethernet sample codes other than IwIP(TCP/IP)

Koichiro Tashiro

Part Number: RM57L843

Hi,

My customer is looking for Ethernet sample code.
I got IwIP example in original thread (above link).
The customer is asking for other protocols such as UDP, etc.

Thanks and regards,

Hi,

The ethernet bootloader uses UDP protocol for data transfer. But the bootloader is also based on LWIP stack.

Hi QJ,

Thanks for your quick reply.
Customer checked the URL, but could not find which one of the code is UDP protocol.
Could you specify the file?

Thanks and regards,
Koichiro Tashiro

The UDP APIs are called in TFTPinit() of tftp.c:

TFTPInit(tTFTPRequest pfnRequest)

{

struct udp_pcb *UdpPcb;

// Remember the application's notification callback.

g_pfnRequest = pfnRequest;

// Start listening for incoming TFTP requests.

UdpPcb = udp_new();

udp_bind(UdpPcb, IP_ADDR_ANY, TFTP_PORT);

udp_recv(UdpPcb, TFTPRecv, NULL);

while(!image_download);

}
