Hi,
My board is OMAPL138,now I want to use the dm9000 on it,the SDK is ti-processor-sdk-linux-omapl138-lcdk-04.00.00.04,after add the dm9000's driver,I use 'ping' to test the network,but it can't work!
I pcap the packet message and found the receive packet is error,I sure that the data I write to the dm9000 chip is correct(use printk to print it when calling dm9000_start_xmit function).
The message is like:
Send Data:
