Bootloader issue changin the program

by d0bl3D on Sat Oct 29, 2016 9:33 pm

I have a Gemma V2 8Mhz, I test my Gemma with the blink program with out any issue. Later i write the random pixels program and loaded in to the Gemma with out no issues, but now im trying to modify the program and the gema don't go in to the bootloader mode. I need to do an special procedure to go into the bootloader mode after the controller have a program recorded? because i just press the button on Gemma and just reset the program don't run the bootloader.

Thanks

What is the red LED doing on the gemma when you press reset? Does it blink? Or does it fade in and out?

Blink, eventually every several resets goes into the bootloader mode, fade in and out. But I don't know if exist any special procedure to go in the bootloader or should go just pressing the reset button.

That is very strange. Can you try a different USB cable? The one you're using may have a loose connection.
