With the netboot you did not yet reach the point when the camera can try to use NFS, making it writeable could make sense before you the flash was erased - during reflashing the camera tried to write logs to the nfs. To get to that point the netboot (server) should first transfer the bootloader (using the ROM bootloader running in the camera), then transfer the linux kernel and compressed root file system - there should be a lot of the output on the program console. So what you are missing is the initial communication between the ETRAX bootloader and the program. The packets from the camera reported by zeros - that is wrong, even if netboot is not running Wireshark ahould report AxisComm packets form the camera (the frequency starts with 10 packets/sec, than drops to 1/sec). This initial ROM bootloader (one of the few Axis closed-source programs, btw) is hard-wired in the ETRAX and you could not erase it. The path between the CPU with on-chip ROM and the Ethernet connector is very short, so Wireshark should report correct AxisComm packets, if not - there is something wrong on the computer/network side. Can you please try running Wireshark on some other computer (no camera software needs to be running there) and make sure you do actually receive these AxisComm packets? Andrey
