Hey guys, so, I've started down the rabbit hole of 1st time flashing, I get "ash: /usr/libexec/sftp-server: not found" Sure enough, there doesn't appear to be an ssh server available in the penwrt-qualcommax-ipq807x-dynalink_dl-wrx36-initramfs-uImage.itb?
Welp, aside from being totally unaware of the -O option, I've successfully just flashed 3 of these puppies with the latest snapshot
