Solved: emonpi update fails with avrdude error : stk500_paged_write(): (a) protocol error, expect=0x14, resp=0x10

Hello, I just updated my emonpi but it seems that AVR's flashing is failing. I get this error :

avrdude-original: Using autoreset DTR on GPIO Pin 7

I tried to run it manually after stopping emonhub but if fails with the same error. It always fails at 98%

Any idea where this error can come from ?

Thanks.

Are you using a RasPi3? This is a known issue, I'm working ona fix? Have you any clues as to what could be the issue?

What image build are you running?

$ ls /boot | grep emonSD

Seems like this is not a RasPi3 specific issue. It seems to affect Pi2s also after a rpi-update

Have you ran an update or rpi-update?

See "BEWARE BEFORE UPDATING !!!". If it's the same as I'm seeing, even emonhub cannot write to emonpi/rfm2pi.

Hi Paul, I've figured it out. This is a separate issue from the serial port issue after update. The AVR upload issue was caused by a corrupted emonPi V2.4 .hex file

The corrupted V2.4 .hex file on emonPi firmware github that was causing this issue has now been fixed. Please try emonPi update again and confirm it flashes successfully for you. Sorry for the hassle.

Hello Glyn,

With to the new hex file, it works now :-)

Thanks you !
