Re: no boot.py after custom frozen modules build

Ok, figured it out, so I will answer my own question in case other run into this (others have as indicated by issue #5320 and elsewhere). I don't know if this is the blessed way to resolve this (please advise if you know a better procedure). Problem : * Manifest files are exclusive OR: only one or t...

no boot.py after custom frozen modules build

I've successfully used a couple of my .py files to build frozen modules, built the firmware, and programmed a 1M Sonoff R3 8266. After incorporating new magic into my code I re-built the firmware and loaded into the Sonoff (erased first, power cycle, etc.). Now I appear to not have a filesystem or b...

Re: [SOLVED] Problem running latest GENERIC_1M firmware on Sonoff

Thanks pythoncoder for the reference -- that got me going! After re-re-reading that I relized that I had the format slightly wrong: I was using the direct file as the freeze arg instead of dir, file. In ../boards/manifest.py I added: # INCORRECT freeze("/home/greg/PycharmProjects/Boiler/validaterang...

Re: [SOLVED] Problem running latest GENERIC_1M firmware on Sonoff

Thank you for this discussion! I had a similar issue where I was getting memory errors and trying to learn how to freeze modules (unsuccessfully thus far). I was able to build ok via jimmo's docker instructions but had no apparent filesystem until I also included the BOARDS=GENERIC_1M to make. Now I...

Re: MicroPython version 1.12 released

The esp8266 port has switched to use per-board configurations and builds, as well as the new frozen manifest feature. It also has optional littlefs support (requires a separate build). Looking for littlefs on my Huzzah esp8266, I downloaded 1.12 from ESP8266 section, import uos and don't see uos.Vf...

Re: Can't load firmware on Huzzah's

Update: I received a new Huzzah and it immediately was able to esptool erase_flash (took 7.9sec). I then loaded uP 1.12 no problem. After power cycling the esp seemed to be stuck in a bootloop: the blue led flickered continuously and connecting to the serial port via minicom showed a stream of chars...

Re: Can't load firmware on Huzzah's

Agreed! That was/is my plan, but I started out just writing to flash/filesystem during development. I'd plan to push the data to the RPi that's on the network already, but I haven't got that done yet. (Need to figure out HOW to do that). I should at least be checking for free space before writing......

Can't load firmware on Huzzah's

Hello everyone! Sorry to ask so much on my first post (and at Christmas!) but here goes... A little backstory I am no expert but I've been working with microcontrollers off and on for few decades (starting with Motorola 6800's in machine a LONG time ago). I was having an intermittent over-temperatur...
