Re: Windows Creator update causing REPL issues and delay in showing drive

Does anyone have a microbit (or any generic mbed-enabled board) that they could try with Windows Creator? It has a USB MSC and knowing if it worked or not would help work out where the issue lies.

Re: MICROPHY_HW_FLASH_LATENCY compile error

Thanks for the report, but in this case I'd say it's better to require the individual board config to define MICROPY_HW_FLASH_LATENCY. Otherwise the main code has too many automagic configuration selections.

Re: NUCLEO_F446RE

Building with cygwin has some difficulties, like: 1) symlinks don't work in cygwin; 2) command-line lengths can overflow; 3) any "strange" characters (eg parenthesis) in path/filenames might break the build. The lcd160cr.py error is related to symlinks not working. The best option is to in...

Re: strange behavior on esp board

It's likely that you're not cleaning up and closing open sockets when they are no longer needed, or that the ESP8266 is being inundated with wifi packets and they are overflowing its internal buffers. Please see https://forum.micropython.org/viewtopic.php?t=3260 for the same problem reported by anot...

Re: What are ESP32 SPI Ports for Micropython SPI(1)?

The default SPI ports are defined by the ESP32 module itself (and actually the ESP IDF is doing all the low-level work here to configure the pins). If you don't provide sck/mosi/miso pins for a peripheral then the "most recent" pins are used, which is usually going to be the default pins f...

Re: Caveats of using mp_sched_schedule() ?

Did I see correctly that this problem is now fixed? There shouldn't be any problems using mp_sched_schedule() like the kind you describe.

Re: Different memory usage in identical devices

The firmware on the 2 devices are not identical. The heap on the second one starts 16 bytes later in RAM. See the 3ffef2c0 vs 3ffef2b0 numbers.

Re: Restarts after loading micropython to esp32

In such a case I'd usually suggest to make sure FLASH_MODE is "dio", but I see that you already did that. Maybe try "qio" instead?

Otherwise it looks like you did everything correctly so I'm not sure why it's crashing.
