Instructions for upgrading Pytrack / LoPy

[hjl]

@bucknall I am failing at this point.. Staying in bootloader means I am in firmware upgrade mode, right?

[bucknall]

@hjl If you use the Pymakr Plugin or a Serial Terminal to view the output from your device when you boot up (with pins GND and G23 connected), you will see a message like this appear:

This means your device is correctly going into firmware update mode.

Now to use the Firmware Update Tool, you must unplug the USB cable from your computer and plug it into another port (sometimes Windows/Mac/Linux, do not release the serial address). Ensure that the jumper wire is in exactly the same position as when you saw the message appear above.

Now run the Firmware Upgrade Tool and 'un-select' the box for High speed Transfer.

This should then run successfully. Let me know if that helps!

Thanks,

Alex

For those using a Pysense for upgrade, there's actually a much simpler way to connect GND and G23: just connect pins 1 and 5 (GND and EXT_IO0) on the external I/O header.

I suppose it's the same on the Pytrack?

@jcaron I can confirm this for PyTrack!
