Hi, I recently attempted to upgrade my new ad2pi via the alarmdecoder web-app. I selected the firmware while it was still in the zip file and the uploader appeared to accept it. However, after some time the upgrade did not appear to work and now the device does not appear to operate correctly when viewing the device output.

Below is the output I get from the device via screen after stopping ser2sock:

Code: Select all

$ sudo /etc/init.d/ser2sock stop
$ sudo screen /dev/ttyAMA0 115200
!no!sn:ffffffff
!boot....................
!wait
!load

If I press enter, the output repeats itself. It appears that I cannot issue any other command to the device.

I have also attempted to upgrade the firmware via ad2-firmwareupload:

Code: Select all

$ ad2-firmwareupload ademcoemu_V2_2a_8.hex /dev/ttyAMA0 115200
Flashing device: /dev/ttyAMA0 - 115200 baud
Firmware: ademcoemu_V2_2a_8.hex
Rebooting device..
Waiting for boot loader..
Rebooting device..
Waiting for boot loader..
Uploading firmware.Error: Timeout while waiting for line terminator.


Is my ad2pi bricked? How can I recover the device so that I can access it and upgrade the firmware?

Hi David,

That's the bootloader that you're stuck in, which happens when a firmware flash fails. It's totally recoverable, but ad2-firmwareupload is a little buggy. It's still going to be the easiest option to get the firmware back on it. I suggest trying to run it a few times. You also might try doing it through ser2sock by replacing /dev/ttyAMA0 with localhost:10000.

Thanks,
Scott
