Hi, I am new on this forum and on FreeRTOS. I try to set up the SAM7 and the PHY to work correctly together but something goes wrong. My try is based on ‘lwIP_Demo_Rowley_ARM7’ demo project. The SAM7 got ARP packets and for each packet it produces the reply packet. The packets never reach the LAN. I would like to know if someone has working code to handle the DP83848C with a AT91SAM7X256. Thanks you in advance. Thoma
You could try looking in the files section of the SAM7 Yahoo group. You might get lucky and find an example for the same phy.
The obvious one, did you change the IP address to be compatible with your network? My problem was with an Olimex SAM7-EX256 board where the PHY address was not correct. You have to carefully review the PHY documentation to see what the default address is and how it is reprogrammed. The FreeRTOS example was not compatible with the Olimex design PHY (KSZ8721BL). If you are sure you received ARP packets, I doubt this is your problem.
