Our work on OpenRTX port for the Retevis C62 progresses. Don’t worry about the LinHT – our efforts are allocated there as well!
This hardware platform is getting a special treatment, as it can be used both as one of a valid OpenRTX targets and a carrier for the LinHT board. Porting OpenRTX will bring M17 mode to C62 users without the need to modify anything. Just flash the radio and go. Very simple stuff.
LinHT, on the other hand, still remains dedicated to skilled hams. The bar is set high, but not intentionally – LinHT is still being developed. When the time comes, the bar should lower considerably. The replacement boards would become available along with the Yocto Linux image incorporating basic analog FM/M17 support (“batteries included”). In the future, LinHT could be treated as a standalone OpenRTX target as well.
LISTENAI’s cskburn is the tool used to flash the C62. It also flashes the DSP firmware, as it uses a separate binary. Recently, we have spotted a bug in the tool’s version 1.31.0. The bug affects the internal argument parser and makes it impossible to set start and stop addresses using the –read argument’s parameters.
A pull request has been offered. For now, it is best to use our fork for flashing (or an older version, probably the 1.25.0 – right after Andreas’ OE3ANC fix was merged).
A great write-up covering C62 flashing process details curated by Vlastimil OK5VAS is available here.
