Trick to update firmware prior to 1.2.1, without the need for a clip

Hi,

Sometimes, if the AM is installed inside a box, it is difficult to enter flash mode without removing the board.

By making a momentary bridge between the last pin of the microprocessor (SWCLK), and the pad (3V3), we achieve the same effect as using the clip, setting the GEKO input high and entering flash mode. Once this mode is entered, it is not necessary to keep the bridge, the LEDs stop flashing and the firmware can be updated without problems

Be very careful when performing this action not to bypass other terminals of the microprocessor!

Health !
