Discussions on the port of Espruino to the ESP32

@MaBecker

Well, this folder is not use for build, it's just for info https://github.com/espruino/Espruino/tree/master/targets/esp32/Changes_V3.1

Kiran Shila

@kiranshila

Oh gotchya

I wonder if it would work if I remove the ota partition

Mark Becker

@MaBecker

so as you stumbled over it, I thought it's time to update it.

Kiran Shila

@kiranshila

Yeah of course

Like I said, the real solution is to utilize all of the RAM, 8M in my case, versus the 4M allocated here

Mark Becker

@MaBecker

the .csv is used to build the .bin file and that one is flashed

Kiran Shila

@kiranshila

The one from EspruinoBuildTools?

Mark Becker

@MaBecker

yep

Kiran Shila

@kiranshila

Ok yeah that's what I thought

Mark Becker

@MaBecker

As far as I can see Mike was using a Espruino before the partition was changed

So it looks like Mike is using Espruino without contributing to the ESP32 firmware, hope he donated to Gordon

Mark Becker

@MaBecker

@kiranshila did you managed to flash the firmware?

Kiran Shila

@kiranshila

Using my modified partition table or the stock firmware?

So it looks like Mike is using Espruino without contributing to the ESP32 firmware, hope he donated to Gordon

Can't speak for him, but I'll donate. This is a pretty neat project and it would be even better if it ran ClojureScript :)

Kiran Shila

@kiranshila

@MaBecker Is the bootloader.bin the normal bootloader from esp-idf or has it been customized for Espruino - I can't quite tell reading the makefiles

Mark Becker

@MaBecker

yes, https://github.com/espruino/Espruino/blob/master/make/targets/ESP32.make#L21

hi i got error while uploading

i try every method, holding boot, holding reset or both

Ákos Lukács

@AkosLukacs

Either the ESP32 is not on COM7, or something else is using COM7. Or even your board might be damaged. What happens if you just connect to COM7 via a terminal app? Do you see the esp's boot messages? BTW that looks like an error from arduino ide, this might not be the best place for arduino advice.

@AkosLukacs

So it's working, try uploading now. But on most boards reset and going to bootloader is automatic...

@K0rkunc

im using esp32 s2
i can connect wifi and enter https sites
but i cant enter https sites
google sheets or etc..
how to fix that

Ákos Lukács

@AkosLukacs

Espruino runs on ESP32 S2? Some code and the error messages would be helpful. Without those we can't help you

Mark Becker

@MaBecker

@K0rkunc better place your issue on the forum in ESP32 section http://forum.espruino.com/microcosms/1086/

@K0rkunc

mmm okey

How we can check my router has internet access Or not using esp?

Ákos Lukács

@AkosLukacs

Just use ping maybe?

Tushar Yadav

@tushar8727_twitter

@AkosLukacs right now I am doing same. I ping www.google.com to check internet availability. But is it good idea to check internet availability?

Ákos Lukács

@AkosLukacs

If ping doesn't work either your Internet or Google is down, sound good enough :)

Ákos Lukács

@AkosLukacs

The last warning? If you don't have spi ram, just ignore it. Some boards have, some don't

hungryforcodes

@hungryforcodes

ESP32 supports SPI PSRAM connected in parallel with the SPI flash chip. While ESP32 is capable of supporting several types of RAM chips, ESP-IDF currently only supports Espressif branded PSRAM chips (ESP-PSRAM32, ESP-PSRAM64, etc).

https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-guides/external-ram.html

So while the chip supports SPI ram the SDK does not atm.

Just “Espressif Branded” PSRAM it seems

@seahindeniz

I've been trying to prepare my Devkitc board ready for Espruino however, that is the error I'm getting recently. I have followed the installation steps on the documentation page and seems like there is something wrong, and I can't figure what is

Ákos Lukács

@AkosLukacs

The devkitc doesn't have PSRAM, so that's normal. You are good to go!

Anything else on the console?

What happens if you just hit enter?

Sahin D.

@seahindeniz

What happens if you just hit enter?

Nothing, actually.

Right now, I have switched to ESP8266 NodeMCU board to continue to testing and in that, I have success. The board is running perfectly.

I'll get back to ESP32 and continue where I left and see what's wrong with it

BTW. this is my first day with Espruino and I love it! I'm actively coding in JS, well mostly in TS however, after setting up ESBuild to bundle the files into one file and pasting it on the IDE, is just perfect 🚀

Mark Becker

@MaBecker

Does anyone has success to flash 2v09?
