Hi, I am a newbie with RTEMS and I need help.
I am porting RTEMS to a board from quicklogic. I'm testing the network
with the netdemos-4.5.0/netdemo and I find out (printing the mbuffer) that the
initial ARP packet that is sent is incorrect.
Below I send the capture packet that is exactly like the mbuffer:
Frame 1 (60 on wire, 60 captured)
Packet Length: 60 bytes
Capture Length: 60 bytes
Destination: ff:ff:ff:ff:ff:ff (ff:ff:ff:ff:ff:ff)
Source: 31:32:33:34:35:36 (31:32:33:34:35:36)
Type: ARP (0x0806)
Address Resolution Protocol (opcode 0x0604)
Hardware type: (0x0000) <- HERE short
Protocol type: Unknown (0x0001)
Hardware size: 8
Protocol size: 0
Opcode: Unknown (0x0604)
Sender hardware address: 0001313233343536
Target hardware address: C1888F0100000000
The "HERE short" isn't supposed to be there. From there the codes are
correct but moved 2 bytes.
I look at the procedure to send out ARP Requests but I could see what is
Please help me.
Thanks in advance,
