MicroPython Newsletter Issue 10
Dear community, It's been a while since the last newsletter and, although we are in unprecedented times, MicroPython continues to move forward, albeit a bit more slowly. Today is MicroPython's 7th Birthday: the 29th of April marks the date on which the first line of code was written, and it's now be...

Re: Can anyone decode this ESP8266 core dump? [SOLVED] please read!
why does pinging make this go away? Maybe because with wifi power saving now enabled (which is perhaps why it wasn't seen before), when the power saving feature runs it runs in a certain location in flash which aliases to the same cache location that pin_intr_handler was in, and evicts the pin_intr...

Re: Can anyone decode this ESP8266 core dump? [SOLVED] please read!
The fact that it crashes with an IllegalInstructionCause right at pin_intr_handler is very good evidence that the crash is because pin_intr_handler is in flash and it cannot read flash because the hard GPIO IRQ has interrupted an ongoing flash operation. Note that pin_intr_handler is called by pin_i...

Re: Problem with CAN after firmware update
I tried the latest PYBD-SF2 firmware, MicroPython v1.12-371-gf534b9976 on 2020-04-16; PYBD-SF2W with STM32F722IEK, and I am able to get the CAN bus working (communicating with a PYBv1.0 via CAN transceivers). The two main things I needed to do to get it working were: enable the PYBD 3.3V rail for th...

Re: Problem with CAN after firmware update
Is it possible to tell standard vs extended frames from the ID? (eg extended IDs would be larger than 11 bits) The early version of the PYBD firmware was from this pull request on github: https://github.com/micropython/micropython/pull/4669 To build it (or any version) do the following (after instal...

Re: Problem with CAN after firmware update
You can obtain the old firmware here: https://micropython.org/resources/firmw ... 1d3ca3.dfu
If that firmware works but the latest doesn't, then it should be possible to track down the bug and fix it.

Re: How to invoke own method from C?
I posted a possible solution to this in https://github.com/micropython/micropython/pull/5660. This allows the "stem" example to work as originally intended.

Re: Pyboard-D fwupdate.py config help
There are two things of note that might be related to the issues here: The USB connector on the pyboard-D is the USB-HS port which does not support the built-in ST USB DFU bootloader . To access the low-level ST bootloader you'll need a WBUS-DIP28 which brings the USB-FS port out to the USB connecto...
