Problem with 20150730 snapshot?

[Steve_M]

Upgraded to the 20150730 snapshot of openwrt-rpi.gz and it's unable to communicate with the HM board. Reverting back to the release version makes things work again, so it doesn't appear to be a hardware problem.

While on 20150730

# dmesg  | grep -i spi

Output on Terminal 1 after running hmdude:

Try it now. The installer was leaving off the plugins so the linkmeterd wouldn't run without them.

 

[Steve_M]

That did it.

Thanks.

Snap shot on July 30th? When I load the firmware update page and check the online repository the latest snapshots I see are from May 31st.... am I missing something?

 

[Steve_M]

This is the OpenWRT / LinkMeter software that runs on the RasPi, not the HeaterMeter firmware that runs on the Atmega.

 

[Bryan Mayland]

Yup and it is worth nothing that the AVR snapshot in the image snapshot isn't necessarily the newest. In this case it coincidentally is.

 

[RalphTrimble]

oh, ok, got it.... I haven't been loading any linkmeter snapshots, just the AVR firmware... I'll check it out....
