Re: why is --flash_mode dio required for my build but not the release?
Not unexpectedly, after doing a clean rebuilding my dev environment, all problems went away. Thanks for all your help along the way and the well documented setup process. I'm still curious about the difference between the basic esp32 build environment that I just built and how the 'release' binary g...

Re: Differences between Micropython ports for ESP32 and ESP8266
Timer Module. This is all anecdotal. The 8266 seemed to let me create an arbitrary number (7 in my case) of Timer objects in the id=20+ range. On the esp32 when I hit 4 the timers started failing. I could create the objects but any attempt to use timer.start() would give me a OS Error 261. I posted ...

Re: why is --flash_mode dio required for my build but not the release?
Thanks for looking into it. I'm just going by my experience - which could easily be some kind of misconfiguration on my part. Here's the output showing make deploy trying to use qio .../ports/esp32> make deploy V=1 python ../../py/makeversionhdr.py build/genhdr/mpversion.h Writing build/firmware.bin...

why is --flash_mode dio required for my build but not the release?
I finally got my own build of micropython running on the Huzzah esp32. Yay! The final issues was dio/qio. Note to other Huzzah esp32 users: You need manually rerun the deploy command with --flash_mode dio Q: Why doesn't the release build require --flash_mode dio? This was a point of confusion for me...

Re: Cross-compiler newbie stuck at square one
... and I now understand why the CROSS-COMPILER variable had that odd syntax: xtensa-esp32-elf-

Re: Cross-compiler newbie stuck at square one
Thanks you both. I'm over the first hump. gcc and all the extensa binaries are prefixed with xtensa-esp32-elf-xyz, so I created a symlink from gcc => xtensa-esp32-elf-gcc. ... and then did the same for g++, ld & size. After that it ran to completion. On to testing... Regarding your other comments 1....

Cross-compiler newbie stuck at square one
I'm stuck at square one getting the cross compiler running under CentOS 7. I believe I followed the instructions correctly but I get permissions error from make on the first file. All the perms seem to be right. Three things seem suspicious: - esp-idf hash is blank - but git log in that folder repor...

Where can I find the sources for ESP8266 machine module?
I'm a newbie climbing up from following tutorials toward looking at micropython source code to get more insights. I'm having trouble navigating the github sources to find things like machine.py or the equivalent. I'm guessing part of my problem is not understanding how the C source get converted in ...
