UDP lpc17xx port missing drivers

Posted by patric11 on February 27, 2016

Dear all,

I am trying to get the UDP port for lpc17xx to work. I am using the NetworkInterface.c from: FreeRTOSV8.2.1FreeRTOS-PlusSourceFreeRTOS-Plus-UDPportableNetworkInterfaceLPC17xx However NetworkInterface.c contains external references to EMACSetNextPacketToSend EMACStartTransmitNextBuffer EMAC_NextPacketToRead

These EMAC functions are NOT defined in the lpc17xx CMSIS driver lpc17xxemac.h. They ARE available in the lpc18xxemac.h.

Can anyone advise?

Thx alot,

Patric

Salut Patric,

FreeRTOS+TCP is the successor of the FreeRTOS-Plus-UDP that you are using. And as the name says, it also includes the TCP protocol. The TCP code will only be included if ipconfigUSE_TCP is defined.

There is an unpublished FreeRTOS+TCP driver for LPC18xx, but unfortunately (AFAIK) there is no port for LPC17xx yet.

What you can do is the following: drop an email ( to "h.tibosch" at the domain "freertos.org" ), and I will send you the current LPC18xx driver for +TCP. It shouldn't be too difficult to get that working for a LPC17xx :-)

Regards.
