ESP32

Postby mobyfab » Mon Nov 21, 2016 2:50 pm

Hi guys,

So there's this new MCU that was just released, from the same company as the famous ESP8266.
It's a dual core running at 160MHz, tons of ram and (external) flash, lots of peripherals. It's perfect for a full IOT solution.
Right now there's support for FreeRTOS, it would be nice to port it to ChibiOS.

Hi,

Interesting but it would be a major endeavour, especially creating an HAL. Boards, compiler and debuggers would required, is there open source support?

Integrated wireless interfaces is great anyway.

The SDK is open source

Here: https://github.com/espressif/esp-idf
OpenOCD support: https://github.com/espressif/openocd-esp32

The wifi and bluetooth libs are still provided as binaries.

Yeah I'd love to see ChibiOS on this although as Giovanni says it's a major undertaking. Although the SDK is open source as mobyfab indicated, I believe there are major parts of the overall environment that are closed by Espressif so not sure how feasible it would be.....

Well, the code for FreeRTOS HAL is open source, so it cannot be too hard. =)

I would also like to see this as well.

I have been away from this scene for a bit, though I may take the first steps as a fun exercise for getting back in touch with ChibiOS and learning a new MCU. When I look at it later tonight I'll keep in touch over on the irc @ #chibios. Cheers!

Hi,

Supporting new MCU families involves finding people working on them, are you volunteering ? :)

I'm a competent esp32 developer, and an ardupilot developer ( runs on chibios), and would love to see chibios ported to esp32, but the low-level bring-up is beyond my skills to do on my own... is there a chat channel where we could try as a group to do this..?

... there is clearly interest elsewhere too... eg: https://github.com/ArduPilot/ardupilot/issues/7751

Hi,

If there is a group willing to give it a try then I could provide a forum area and try to support the effort. Getting started with simple drivers should not be a huge effort. The plan is simple:

1) Make a clock tree initialization, it does not need to be fully configurable initially.
2) Make a PAL driver, easy usually.
3) Make a serial driver, easy usually.
4) Make a simple demo running the test suite on serial output (the same you see for STM32).

Now you have the bare minimum for a "supported platform". From here you can decide on which drivers to invest your time, the hard ones are USB and Ethernet.

Do you need to support a specific device or a whole family? the latter can be more complex, see the STM32 source tree, there are hundreds of those.

A forum area, and whatnot sounds great. I'm in. Who else?
