I’m about to tackle the firmware update for the first time, and referring to the documentation and the iFixit guide, I have a question about power.
I’m assuming this should be done with the batteries disconnected and the mains power off; however the photographs on the iFixit guide show the batteries connected.
I had the same question and asked it here:
The second link has an answer by @minute:
josch: well, the manual says you should remove the batteries when opening the device, so that leaves only wall power. but you don’t have to follow that advice of course ^^
I interpret this, that the official advice is to have the batteries removed and only wall power attached while upgrading the lpc firmware.
Many thanks. It looks like it needs power to the board but the batteries should be disconnected just as the usual precaution against shorts.
Another thing I noted is that the fw compilation has an error about the lpcrc binary not being found; I don’t understand makefiles at all well but I think the problem is it is being called before it’s created? There is a line in there to build it and I just did that manually and the build succeeds.
I don’t think this is documented yet. I create this MR against the handbook to fix this issue:
It also mentions that REFORM_MOTHERBOARD_REV has to be set and that flash.sh is interactive.
Pleased to report it all went off without any issue. I also have my replacement batteries in, now I’m just awaiting the new battery boards.
