ESP32 TWAI / CAN on NuttX

Hello world :-) What is the current support of CAN / ESP32's TWAI on NuttX? What hardware interface bus modules would you recommend? I would like to use this bus for bidirectional remote control unit with some buttons and display on ~5m cable :-) Any hints welcome :-) Tomek -- CeDeROM, SQ7MHZ

Building NuttX on Chrome OS

I have been tinkering with Chrome OS recently just to keep myself informed.  If anyone cares, I have been able to build and run the NuttX simulator on Chrome OS.  Debian Linux is available on Chrome OS, so why is this a thing? - A ChromeBook is a highly memory constrained platform and it is p

Re: undefined reference to 'inet_ntoa_r'

Hello Gustavo, By "connected esp to the internet" do you mean that your board has public IP (not in the local network) or accessible via NAT? Because if you just connect board to home WiFi router that provides Internet, this is not "connected esp to the internet". If that is the case, then better

Hi, Alan! Thank you and Petro for the support, it's compiling now! I also connected the esp to the internet, but for some reason both 'nslookup' and 'ping' are failing and when I start the webserver it gets stuck in the 'starting webserver' message. Em sex., 17 de mar. de 2023 às 08:52, Alan C. A

Questions about ble/wifi

Hello! I started working on a project for my university. The idea is to make a smart home proxy using NuttX and ESP32-devkitc. I tested the already available configs(wifi/ble/sta_softap/blewifi) to see if they work and they seem fine using the stable release V10.3.0. Using the latest version I go

I just noticed it is documented only for ESP32S2: https://nuttx.apache.org/docs/latest/platforms/xtensa/esp32s2/index.html Should be extended to ESP32, ESP32C3, ESP32C6 and ESP32S3. BR, Alan On 3/17/23, Sebastien Lorquet wrote: > Oh great, I'll test that, thanks! > > Sebastien > > Le 17/03/20

Re: undefined reference to 'inet_ntoa_r'

Hi, Dont you need the full ESP-IDF to build the bootloader and stubs? If you have a simplified build method I am interested. Last time I checked esp32-c3, it worked perfectly, but the bootloader build was a bit cumbersome (fortunately it's only needed once, which is okay). IIRC it even requ

You need to download the "xtensa-esp32-elf" No idea why they put xtensa-esp32-elf-gdb before the real toolchain. On 3/17/23, Alan C. Assis wrote: > Hi Miguel, > > Nice to hear it. > > BTW, you don't need to use esp-idf, it is overkill (you will waste too > much disc space). > > Just download the

Hi Miguel, Nice to hear it. BTW, you don't need to use esp-idf, it is overkill (you will waste too much disc space). Just download the latest Xtensa ESP32 toolchain: https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-guides/tools/idf-tools.html#custom-installation BR, Alan On 3/

Re: undefined reference to 'inet_ntoa_r'

Hi Gustavo, Enabling all the network needed features on NuttX is very time consuming, so this is a good idea to start with a working example. In this case nsh is not the recommended starting point, but wapi (wifi board profile). Try this sequence: make distclean ./tools/configure.sh esp32-devkit
