Im trying to update Herelink Air Unit firmware to latest beta with flasher_mac - but it wont launch correctly (OSX 10.14).

./flasher_mac

Herelink Air Unit itself is shown in macbook lsusb command output:
Bus 020 Device 009: ID 2717:ff28 2717 Telepathy Air Serial: xxxxxxxx

Im also able to adb into Air Unit:
adb shell
$ df

It seems that flasher_mac is not able to detect herelink air unit properly for some reason.
Please help @sidbh

Tried also different macbook with older MacOSX (10.13) - does not work either, a bit different error:

/Users/macbook/Downloads/flasher_mac ; exit;

Does it mean that flasher_mac requires MacOSX 10.15 - @sidbh?

Got it finally flashed with flasher_win on another laptop. Windows flasher behaved also quite unstable - it performed random exits for the first 3 times I run it - 4th time it started the fw download and pulled it through.

Was that a Windows 10 PC 64

5

Yes - win10.

@frame You were getting the error because you had adb server running as well at the same time, you need to do adb kill-server before be able to run the flasher_mac program.

Thank you for the explanation @sidbh.
