Hanging issue in RL-TCP net keil arm

Rajmohan R

Hello,

Iam using LPC2378 uc for Ethernet application (udp/ip communication). Iam receveing UDP data continuously with some interval from PC and sending acknowledgement to PC. My code has no error.

Some time it's working for 6 hours continuously but some time it's get hanged immediately. This hanging issue is happening always after few hours. I am using RL-TCP net source code..

Iam not using any interrupt right now,

Plzzz anyone suggest solution to solve this hanging issue.

Thanking you

    Thank you for your reply sir,

    But I use to communicate uC to PC directly, is it affect network stack? Or I have to implement interrupt, to avoid this uC hanging?

    I received UDP data @100MHz and send that to SPI @10MHz after that Im acknowledge to UDP @100MHz. This routine will repeat.

    Is possible to occur issue in SPI?.
