Yellow LED constantly on for red board

[rieck]

The yellow LED on my red board stays on continuously, which typically signals an incorrect firmware version (color). However, I have compiled the firmware correctly using make COLOR=red, and the watch is actuially functioning normally. The only issue is that the yellow LED remains lit. It’s not due to a short circuit from the case, as the LED remains on even when connected to USB. Does anyone have any ideas about what might be causing this?

Alas the issue is with uppercase vs lowercase: you have to make COLOR=RED for it to work.

Is there some make-fu we can use to make these lines case insensitive? Or uppercase whatever the input is?

Oh, thanks for the swift response!!

COLOR := $(shell echo $(COLOR) | awk '{print toupper($$0)}')

or

COLOR := $(shell echo $(COLOR) | tr '[:lower:]' '[:upper:]')

would be two options. They require the shell subcommand, which is not present in BSD make to my knowledge, and likely they both do not work on Windows.

I think the best thing to do is to have it abort if the COLOR line has an unrecognised colour.

or modify the makefile to skip the COLOR argument, and always run it with your watch colour

I'm having the same issue. Is there way to turn this off for the pre-built firmware? Do I need to build the firmware with the flag?
