Re: Problems with ESP32-s3

Hiya! You not provided anywhere near enough info to be able to help you. ESP32-S3 is flashed at 0x00 and flashes and works fine if you are using the correct board definition/firmware version for the dev board you have. What ESP32-S3 boards are you using? Need to know that to determine the PSRAM and ...

Re: ESP32-S2 Mini Feather - which version of Micropython?

The S2 Mini from Wemos is the one you wan for that board. https://micropython.org/download/LOLIN_S2_MINI MicroPython is usually not matched to a specific board, but rather to a version of the MCU chip on a board, unlike CircuitPython which is firmware built specific for each board. The exception her...

Re: Choosing ESP32 variant

Thanks for the shout out folks :) Yeah for teaching or just low entry "throw away money" prices, you can't beat the Lolin S2 Mini - It's crazy they do tham at that price, but it's a win for anyone wanting to get into ESP32 dev with an entry point product. I use to use a lot of Lolin boards before I ...

Re: Problem with esp32-s3 firmware

esptool is too old. Update it via pip to 3.2 or later.
Don't use -chip auto always specify --chip esp32s3 and you would have seeing error saying no esp32s3 found.

Or you can just flash the pre-built binaries? :)

mpremote 100% works on a Mac. I've been using it for months.
What specifically is not working for you?

Re: esp32 with 8mb spiram only 4mb detected

There are folks that develop with the IDF that do some RAM bank switching to get access to the entire 8MB, but we can't do that with MP when we are using the PSRAM for the heap as your heap would disappear ;) This memory address space limitation is fixed in the new ESP32-S2 and newer chips. Cheers, ...

Re: ESP32 Wroom with SPIRAM support

Actually, the SPIRAM use will dramatically effect the speed of execution if you fill the cache. The current (Non ESP32-S2) chips use a shared cache with Flash and PSRAM, and if you fill the cache with PSRAM stuff and it needs to be flushed, all flash is removed, and then needs to get reloaded again....

Re: MicroWebSrv2, new asynchronous Web server for MicroPython (+Routes +WebSockets +Template engine).

Ok, I just found this issue: https://github.com/jczic/MicroWebSrv2/issues/22 It states .pyhtml files are not processed for default pages. That's a real shame. I get I can manage the '/' route and do a redirect to it, but that's another slow page change running on a microcontroller. Is there a specif...
