Disabling bootloader mode.

  • Hi all, sorry if this isn't the right place to post. I am using a GPy with some reflectance sensors, one of which connects to P2/G23. Occasionally when I start up my device, the GPy will not run the program due to entering bootloader mode. Unfortunately a pull up resistor will affect the reflectance sensor output, so that's not an option. I was wondering if there was any way to disable entering bootloader mode by connecting P2/G23 to ground?

  • @robert-hh Thanks for the info. I was hoping to find a software solution before I started looking at hardware, thanks for the suggestions though.

  • @SmithM97 As far as I know, the bootloader that checks P2 is located in ROM. So it cannot be changed. Possible option I see for you:

    • change the pins. P2 can reliably used as output pin after the device booted.
    • change you circuit, if possible, to enable the connection between P2 and you sensor after boot.
