Porting @MicroPython to @Apache_Mynewt has begun! First Target: #PineTime Smart Watch @PINE64 https://github.com/AppKaki/micropython/tree/wasp-os/ports/mynewt

@MicroPython is being ported to @ZephyrIoT... Shall I port MicroPython to @Apache_Mynewt, #NimBLE and #MCUBoot? So that MicroPython on #PineTime Smart Watch @PINE64 will support Wireless Firmware Updates the same way as FreeRTOS and Mynewt? 🤔 https://github.com/micropython/micropython/tree/master/ports/zephyr

Can #MicroPython run on #PineTime Smart Watch @PINE64 #nRF52... Without Nordic SoftDevice? Let's find out... https://github.com/lupyuen/wasp-os

Install Firmware and Roll Back... #FreeRTOS @JF vs @Apache_Mynewt on #PineTime Smart Watch @PINE64 ... Test Driving new Operating Systems has never been easier! https://youtu.be/0FIYZ9tlI-Q

From @Apache_Mynewt to #FreeRTOS @JF ... Switch Open Source Operating Systems wirelessly on #PineTime Smart Watch @PINE64 ! Stay tuned for more Operating Systems https://youtu.be/OeHS3SEOB88

Conflicting Vector Tables for #MCUBoot Bootloader and #FreeRTOS Firmware... Here's how we fixed it to support all operating systems on #PineTime Smart Watch @PINE64 https://lupyuen.github.io/pinetime-rust-mynewt/articles/dfutest

#FreeRTOS Firmware by @JF works great with the new #MCUBoot Bootloader on #PineTime Smart Watch @PINE64 yay! PineTime Owners can soon Download and Install any operating system wirelessly... Stay tuned! https://lupyuen.github.io/pinetime-rust-mynewt/articles/mcuboot

Here's how the #PineTime FOSS Community is using OrangePi @orangepixunlong #whatIdowithorangepi https://coffeespace.org.uk/projects/flashing-pinetime.html

Debugging #FreeRTOS + #MCUBoot Bootloader with @JF on #PineTime Smart Watch @PINE64 ... Super Educational for me because I know nothing about FreeRTOS! 😀 https://github.com/lupyuen/pinetime-rust-mynewt/releases/tag/v4.1.5

Testing @PINE64 #PineTime's new #MCUBoot Bootloader with #FreeRTOS @codingfield... And getting a cryptic message 😉 https://lupyuen.github.io/pinetime-rust-mynewt/articles/mcuboot

Happy to report that #PineTime Smart Watch @PINE64 hasn't bricked yet... While swapping 3 Wireless Firmware Updates again and again... Thanks to the open source #MCUBoot Bootloader from @Apache_Mynewt and @ZephyrIoT! https://lupyuen.github.io/pinetime-rust-mynewt/articles/dfutest

Today I learnt 1️⃣ It's possible to run #Arduino on #PineTime @PINE64 2️⃣ #NimBLE and #MCUBoot may possibly coexist with Arduino 3️⃣ PineTime Owners may soon be installing Arduino wirelessly… Just like Mynewt and FreeRTOS! Check out @atc1441's firmware: https://github.com/atc1441/ATCwatch

Update Firmware over Bluetooth LE on #PineTime Smart Watch @PINE64 ... With nRF Connect @NordicTweets, #NimBLE, #MCUBoot and @Apache_Mynewt https://youtu.be/thLhGUl9-CU

#PineTime Smart Watch Firmware @PINE64 successfully updated over Bluetooth LE... With #NimBLE, #MCUBoot and @Apache_Mynewt yay! https://github.com/lupyuen/pinetime-rust-mynewt/blob/master/scripts/nrf52/test-dfu.sh

New Firmware successfully uploaded to SPI Flash of #PineTime Smart Watch @PINE64 over Bluetooth LE yay! https://github.com/lupyuen/pinetime-rust-mynewt/blob/master/scripts/nrf52/test-dfu.sh

Wireless Firmware Updates done right on #PineTime Smart Watch @PINE64 ... With the open source #MCUBoot Bootloader from @Apache_Mynewt and @ZephyrIoT! Here are the complete details https://lupyuen.github.io/pinetime-rust-mynewt/articles/mcuboot

Next steps for Wireless Firmware Updates on #PineTime Smart Watch @PINE64 ... And a FOSSy Collaboration with @minodesign! https://lupyuen.github.io/pinetime-rust-mynewt/articles/mcuboot

You can recover a bricked #PineTime Smart Watch @PINE64 ... Just press and hold the watch button for 5 seconds when it boots! Here's how we implement this with open-source #MCUBoot Bootloader https://lupyuen.github.io/pinetime-rust-mynewt/articles/mcuboot

Instructions for testing #PineTime #MCUBoot Bootloader @PINE64 ... Yep we're ready for Firmware Updates over Bluetooth yay! https://lupyuen.github.io/pinetime-rust-mynewt/articles/mcuboot

Load your own Boot Logo to #PineTime Smart Watch @PINE64 ... Thanks to a PNG Converter coded in #RustLang https://lupyuen.github.io/pinetime-rust-mynewt/articles/mcuboot
