Hi all, there is a new rom file system (for soloboot) and tcpborphserver3 (copy to nfsroot/usr/local/sbin) for nfsboot in github ( https://github.com/ska-sa/roach2_nfs_uboot/)
There is an email detailing how to upload a new romfs but it's fairly straight forward, set up a tftp server, use a terminal emulator like minicom and boot into uboot. Then type "run tftproot". You can also use "run newroot" and then y-modem the file across, so no need for tftp but this takes a very long time! tcpborphserver3 now supports borph upload. There are 2 ways of using this command: 1. As Paul explained: you can use the upload_bof method in the FpgaClient class in corr to upload a bof file to your ROACH. Once it's uploaded, though, it will skip uploading it unless you force it to do so. Use progdev to program the device as usual. 2. Use the katcp command "?uploadbof port filename". The boffile can now be sent to that port using socat or netcat or similiar.
