Hi,
Is there firmware available to flash a WAPS-232N gateway with the RockChip rkdeveloptool over serial connection to the serial port on the PCB? The firmware I have found so far are tar.gz encrypted files probably only suitable for updating via the Web GUI (though it is conceivable that it contains the files needed to flash via serial).
Background:
I have received, for free, a second-hand WAPS-232N gateway which allegedly should be working, however, it appear to be missing firmware. I have attached to the serial port on the main PCB and receiving messages from the device, so it appears to be alive, except it is reporting “no sys part.“ indicating that the firmware is missing.
Best regards,
Morten
