I am trying to load an OpenWRT on a BCM963xx Router (SmartRG SR515ac), I managed to connect to CFE using a UART-USB, change the image server IP, but when I run the load command I get an error like this:
CFE> r 10.20.0.16:vmlinux.elf
Loading ramdsk image 10.20.0.16: to address 0x00000000..
Loading 10.20.0.16: ...
Loading faile.: CFE errr -21
*** command status = -21
Using wireshark I can see ARP communication between CFE and the server, but no other traffic.
After some ARP retries the CFE gives up and return the error shown above.
Is there any reason why the router is not seeing the ARP replies and continuing with the TFTP load?
The router requests are padded to 60bytes but the reply are just 42 bytes long, could that be it? Can I force the arp table to add the padding to replies, either on Windows or linux?
