Hi,
in Step 23 of the new build guide, checkup wizard ok, all buttons work, sound works, backlight and so on. But when I insert SD Card and press button C, I see the flashing info, but when I release the button, nothing happens. I also waited for 30s as mentioned in the guide. Any idea what I can check?
Hi @Yves Doesn’t look like you have any solder on the 4th pin from the right? You don’t need to solder the last 3 pins but that 4th pin is a data line.
That was the mistake! Tank you! Now it works great!
“three rightmost pins” … not four,Yves you idiot
@bitfogav, you’ve solved this problem real quick and effective, it’s really neat having you on the forum 
@Yves, is your MAKERbuino working now? Pics or it didn’t happen 
yoooooo this was my problem too. I went ahead and cleaned up my joints on my SD card reader and boom, now mine is properly uploading the boot loader! bravo
I’ll mark the topic has solved…
