Hi, Jake, I think the problem might be that your DHCP server if offering a 169.254.x.y address. This address range is reserved for “auto-config” IPs so the LWIP code on the microblaze might be refusing to use it. I suspect that it is then timing out and inventing its own auto-config IP address,

Hi Jake, I've seen that the ICAP software initialization fails sometimes on boot. However I've never seen a problem with actually using the ICAP module to reprogram the device, so this is a back-burner issue for now. After 240 seconds the microblaze DHCP process times out, and goes with a predete

Hi Jake, Maybe this helps. ICAP = Internal Access Configuration Port of the FPGA and it allows the FPGA to reconfigure itself, internally e.g. in the case of the SKARAB, the microblaze can issue a command to reconfigure the FPGA if necessary without having to reset the FPGA externally - very usefu
