Workaround
I’m not sure what was going wrong with what I was doing initially, but, thanks to @tapdattl@lemmy.world, as suggested, I disabled the tftp server system service, and, instead, started it with the following command:
sudo in.tftpd -L /srv/tftp --verbose --permissive -s
and it then flashed successfully.

I’m trying to flash firmware to a router (Archer C7) using TFTP, but, when the router makes the request for the firmware file over TFTP, the TFTP server responds with the following error
Error code: Access violation (2) Error message: Only absolute filenames allowed
This is the config for tftpd in
/etc/conf.d/tftpd:TFTP_OPTIONS="-s" TFTP_DIRECTORY="/srv/tftp" TFTP_USERNAME="tftp" TFTP_ADDRESS="192.168.0.66:69"I have the firmware file in
/srv/tftp, and both the firmware file, and/srv/tftphavechmod 777permissions.The TFTP server is running on Archlinux, and is installed as
tftp-hpafrom the arch repos.
If I test as a client, I can get it to download if I specify the full (absolute) path to the file /srv/tftp/filename, so it seems that the config isn’t pointing the server to /srv/tftp as the relative path… How would I go about fixing that?
As shown in my post, I have that in my config. I have tried it with both
-s, and--secure.
