How to fix when keyboard doesn’t work after uploading firmware Soldering Guide When I click the Firm Up button it runs, briefly stops blinking and then continues to blink. I checked the PCB, and I get the HIDBoot item in my devices, and the LEDs are all blinking. I have the 4×6 layout on the b.pad. What am I to do next?

If the leds are blinking, most of the reasons are coming from bad soldering – electric short, wrong direction(polarity)… Please check solderings. And could you tell me whether keyboard is working? Thanks. Hojin.Yi Author Posts Viewing 3 posts - 1 through 3 (of 3 total) You must be logged in to reply to this topic.
