You should also be able to use Control-C to stop the running program and be dropped to the REPL prompt.

I'm also using the latest dfu-util, built from source. I just thought I'd mention that in case you run into any differences.

The latest dfu-util supports -s:leave properly when flashing, which is why I'm using it (just an FYI)

So the 16K winds up being what dfu-util uploads by default. So the firmware is laid out as 16K vectors + 112K MSD area + firmware.

I'll guess that you need to send \r as the end of line rather than \n

Most serial terminals send \r when you hit ENTER.

The firmware is split into 2 pieces. 16k plus the rest.

This is because the lower flash blocks are smaller and better to use for the mass storage device.

Perhaps move the gc.disable to just before the loop?

I suspect that a hc during initialization is causing your memory error with gc disabled earlier.

At the datasheet level, all of the peripherals are numbered starting from 1. So you have I2C1, I2C2, SPI1, SPI2, UART1, UART2, TIM1, etc. The Led isn't really a datasheet item, but if you're trying to rationalize stuff from the datasheet to python its easier if there isn't a +1/-1 to always deal wit...

I thought I would mention that I've been using a Netduino Plus 2 which has an Arduino shield footprint and uses the same microcontroller as the pyboard.

I haven't added the support for the sdcard yet (its wired up as 1-bit SPI) nor the ethernet, but that will come in due course.

Since I flash new versions of MicroPython quite frequently, I decided to add a BOOT0 switch. The pyboard is mounted in a SliceCase Boot-Switch-800.jpg The red wire runs to 3.3v and the white wire runs to the pull-down resistor on BOOT0. A dab of hot glue holds the switch in place on the processor. N...

Two were broken for me earlier as well, but they seem to be working now as well, so obviously they've been fixed.
