Re: Using Eclipse with OpenOCD to build and debug ESP32

I don't think so, from what I remember the JTAG connects directly to the CPU core, not to the GPIO logic. If it does boundary scan, it likely maps to internal signals, not to the GPIOs. I'll ask the hardware engineers, just to be sure. Did you ever find out about boundary scan support? Internal sig...

Re: Device Initiated Protocomm Messages?

Thanks for your advice ESP_Anurag! I really like the protocomm design and working with that portion of the codebase. For my case, I was thinking about BLE transport and re-using the established session encryption. But I think that your suggestion of just calling `protocomm_req_handle` directly to ge...

Device Initiated Protocomm Messages?

Protocomm is awesome!

I wonder if it is possible to have the device begin a message transmission to the smartphone? For example, say a GPIO input was pressed, to send a message to the phone (ideally, encrypted with the same session).

Dialogflow gRPC Support

I'd like to ask a question about the gRPC support mentioned in the recent esp-va Dialogflow announcement (great news BTW!). I'm very interested in gRPC support on the ESP32 (I hope this means gRPC direct usage w/HTTP2, and not the gRPC transcoding -> REST API). I thought it was not possible to run t...

Re: LLVM for Xtensa

Wow this is amazing news! Congratulations to the Espressif team! The first question that came to my mind is, does this enable us (or get closer) to use the languages which target LLVM (e.g. Rust, Nim, Zig, etc)? For Rust specifically, would Espressif also host a fork of "rust-lang/rust" and "rust-la...

Re: Gripes on ESP32/ESP-IDF

I can't speak to the hardware (I'll be honest -- I've had some flakiness with the radio, and I2C), but if you don't like esp-idf FreeRTOS, there is Amazon FreeRTOS (the current maintainer of the official FreeRTOS project), with ESP32 Espressif DevKit as a primary target they have selected. Support f...

Re: What's the current state of drivers for the MMU?

Well, my use case is for dynamic loading of modules (obtained via the network from a trusted server). But the content of the modules is user-generated, so I would like to sandbox/prevent memory reads -- and hopefully peripheral access -- while executing those modules (via PIDs).

Use ESP32 as MCU (no radio) -- Certification needed?

Hi, certification experts! The ESP32 seems to be a decent CPU with a decent toolchain, for a decent price -- not bad! I love the GPIO matrix, the dual-core/FreeRTOS, and there are ample peripherals (CAN, QSPI, ...). It's good enough that I would consider using it as an MCU, even without the flagship...

Combined UART Log messages w/binary data packets

Hi Espressif/ESP32 users, I am trying to use an ESP32 device to send custom messages to a computer via USB (e.g. CP2102<->UART), as well as be able to record all console messages (boot log, printf, etc) to display them on the computer and/or save them to a log file, etc. I'd like to be able to use a...

Re: protocomm, esp_prov questions

So if I wanted to contribute a PR for the flexibility to use flatbuffers instead, would that be accepted within the protocomm component? (or would I have to fork protocomm on my own, and make a "flatbuffercomm")? The only place where protobuf is used in protocomm is the session security (protocomm_...
