I suspect a mismatch between your casperfpga version and ROACH2 filesystem. Like progremote is not supported? We are running different versions so I can't be sure which version you should be running, but it looks like these are the latest public releases:
romfs (root filesystem for Linux, which should have the new tcpborphserver): https://github.com/ska-sa/roach2_nfs_uboot/blob/master/boot/roach2-root-phyprog-release-2015-04-01.romfs and You might need a new kernel to go with it, if your version is very old: https://github.com/ska-sa/roach2_nfs_uboot/blob/master/boot/uImage-roach2-3.16-hwmon From https://casper.berkeley.edu/wiki/ROACH_kernel_uboot_update the procedure to update the root filesystem is NOT SHOWN. Please do NOT overwrite uboot (step #2 and #3), because then you can't recover from a failed upload and you will brick the board (then only recoverable with a jtag flash). IIRC, the command is run newroot and then you transfer the file via ymodem. printenv will show you the available macros. It's quite slow (many minutes) over the serial interface. You can also do it over the network, but then you have to setup a tftp server. As long as you don't overwrite uboot, you can recover from any failed upload by trying again. I'm cc'ing Marc Welz and Alec Rust for their comment in case I've got the versions wrong, or there's a newer version that you should be using that hasn't been uploaded to git yet.
