Tasmota
Alternative firmware for ESP8266 with easy configuration using webUI, OTA updates, automation using timers or rules, expandability and entirely local control over MQTT, HTTP, Serial or KNX. Full documentation at
Have a check at this: https://github.com/arendst/Tasmota/issues/10202

Project mention: File Transfer using Bluetooth Classic, ESP32, SD SPI, and Android | reddit.com/r/arduino | 2021-04-23
-
Scout APM
Scout APM: A developer's best friend. Try free for 14-days. Scout APM uses tracing logic that ties bottlenecks to source code so you know the exact line of code causing performance issues and can get back to building a great product faster.

Project mention: PinePower Desktop Power Delivery Port stopped working | reddit.com/r/PINE64official | 2021-09-20
I originally had a different issue where my Pinecil would randomly reset when soldering, somebody found this github issue from someone else with exactly the same problem and a video https://github.com/Ralim/IronOS/issues/975
-
Project mention: Honeycomb LX2 ARM Workstation: An Alternative to x86 | news.ycombinator.com | 2021-08-26
Heh. Embedded Development Kit II (EDK2) is a "modern, feature-rich, cross-platform firmware development environment for the UEFI and PI specifications". https://github.com/tianocore/edk2

mongoose-os
Mongoose OS - an IoT Firmware Development Framework. Supported microcontrollers: ESP32, ESP8266, CC3220, CC3200, STM32F4, STM32L4, STM32F7. Amazon AWS IoT, Microsoft Azure, Google IoT Core integrated. Code in C or JavaScript.
Cesanta Software mongooses – Update available
-
nexmon
The C-based Firmware Patching Framework for Broadcom/Cypress WiFi Chips that enables Monitor Mode, Frame Injection and much more
so the major reason for the use of raspberry pi is support for seemoo labs(check them out because for wireless security research they do super interesting stuff) nexmon platform. nexmon is a binary firmware patching platform that is aimed at providing patches to allow mobile radio chips to do things the stock firmware does not support, ie it is named for providing monitor mode on a nexus phone.

I just got my Launch keyboard (very classy by the way, I'm a fan so far). The only firmware update I'm finding is via the fwupd utility, but I'm on Windows. I know the keyboard is pretty new, and there may not yet be a firmware update, but how can I ensure that the firmware remains up to date moving forward?

-
I checked for DAPLink, but this seems to require keil, based on what I read in the readme.

Project mention: Has anyone got python/micropython on RISC-V working? | reddit.com/r/RISCV | 2021-08-03
-
-
I don't know about Windows, but it runs on Linux, yes, and it works on all M1 Macs (as targets) to my knowledge. See: https://github.com/libimobiledevice/idevicerestore/pull/406
-
stm32-bootloader
Customizable Bootloader for STM32 microcontrollers. This example demonstrates how to perform in-application-programming of a firmware located on an external SD card with FAT32 file system.
Here's a bootloader "library" that might be useful. You need to add your own code to get the actual firmware image from somewhere (UART, an SD card, or whatever), and then you just pass it off to the "library" for flashing.

Project mention: Where to get a good NanoVNA v3? I'm fine with copies. I just want it to work properly. | reddit.com/r/RTLSDR | 2021-07-24
I bought mine from Nooelec. They're listed as an official distributor on edy555's GitHub repo.

I recommend looking at EasyAVR and its use with custom boards. This may be easier than working through the Arduino IDE once you get the initial legwork done. There are lots of alternatives too, such as:
-
Update: I tried this version but i have the same problem, run via USB but not from SD
-
IoTGoat
IoTGoat is a deliberately insecure firmware created to educate software developers and security professionals with testing commonly found vulnerabilities in IoT devices.
Project mention: We are cybersecurity researchers who wrote a book teaching people how to hack the Internet of Things, called Practical IoT Hacking. Ask us anything! | reddit.com/r/IAmA | 2021-03-27We have a chapter on methodologies in the book and go into a lot of detail on how we test. We also created the free OWASP IoT Goat project - a deliberately insecure IoT firmware that you can use for a testbed.

Project mention: Gameboy Esp32, yes please! Picking this up the second it releases. | reddit.com/r/SBCGaming | 2021-04-29
I wonder where the OS came from. I kind of expected to see Retro-ESP32 when it booted up 😅

Yi-hack-Allwinner for the Home 1080: https://github.com/roleoroleo/yi-hack-Allwinner
-
Find link github from comment, download file project-kbfirmware.json and upload into kbfirmware.com/ and see handwiring grid and pins for microcontroller.

Project mention: I wish the Steam Deck would come with GPIO pins. | reddit.com/r/SteamDeck | 2021-09-06
Did you look up schematics of the steam controller? I suspect the interface to the device controls on the deck will run through USB and be an iteration of the steam controller. https://github.com/greggersaurus/OpenSteamController/blob/master/ReverseEngineering/Luna_maiboard_V000456-00_rev3.md would suggest two pins unused/undetermined. Yes, it's an input device and would require driver/firmware changes, but as long as hardware capability is there, the rest is a software problem.

Project mention: Computer randomly starts to play one continuous beep until I kill pulseaudio | reddit.com/r/archlinux | 2021-09-17
Sounds like the sof-firmware beeping bug. Try booting with the snd_sof.sof_debug=1 parameter and follow https://github.com/thesofproject/sof/issues/3868

micropython-ulab
a numpy-like fast vector module for micropython, circuitpython, and their derivatives
Has anyone of you managed to install a micropython version with ulab for your esp32? I tried the procedure on the ulab github but without any succes. When I try it stops at sth like: "no submodule. stop."
