Creating a Firmware Image for flashing #PineTime Smart Watch @PINE64 over Bluetooth... Based on open source #MCUBoot tools https://lupyuen.github.io/pinetime-rust-mynewt/articles/dfu

#MCUBoot is an open source Bootloader used by @Apache_Mynewt, @RIOT_OS and @ZephyrIoT... Here's how #PineTime Smart Watch @PINE64 uses MCUBoot for flashing firmware over Bluetooth https://lupyuen.github.io/pinetime-rust-mynewt/articles/dfu

Creating a Firmware Image with #MCUBoot @Apache_Mynewt... For flashing #PineTime Smart Watch @PINE64 over Bluetooth https://juullabs-oss.github.io/mcuboot/design.html

Building and testing #MCUBoot Bootloader @Apache_Mynewt for #PineTime Smart Watch @PINE64 ... MCUBoot may become the Unified Bootloader for PineTime! https://juullabs-oss.github.io/mcuboot/

#NimBLE @Apache_Mynewt is an open source #Bluetooth Stack for #nRF51 and #nRF52 @NordicTweets... Works great on #PineTime Smart Watch @PINE64 ! Here's how we port NimBLE to any #embedded #IoT operating system https://lupyuen.github.io/pinetime-rust-mynewt/articles/dfu

Demystifying #PineTime's open source NimBLE Bluetooth Stack... With #Pinebook Pro @PINE64

Writing to #nRF52832 Flash ROM @NordicTweets on #PineTime Smart Watch @PINE64 ... For flashing PineTime Firmware over Bluetooth LE https://lupyuen.github.io/pinetime-rust-mynewt/articles/dfu

Here's how we'll implement Firmware Updates over Bluetooth LE for #PineTime Smart Watch @PINE64 ... With the open source MCU Manager Library that's used by @Apache_Mynewt and @ZephyrIoT https://lupyuen.github.io/pinetime-rust-mynewt/articles/dfu

Good #PineTime Evening @PINE64 (with lockdown coconuts)...

Hi #PineTime Firmware Devs: Here's the proposed Flash ROM Layout for PineTime... So that Owners of PineTime @PINE64 may easily update (and rollback) their firmware via Bluetooth https://lupyuen.github.io/pinetime-rust-mynewt/articles/dfu

#PineTime Smart Watch @PINE64 will never get bricked... Just roll back firmware updates with MCUBoot... Which is used today by @Apache_Mynewt, @RIOT_OS and @ZephyrIoT https://lupyuen.github.io/pinetime-rust-mynewt/articles/dfu

#PineTime @PINE64 Firmware Upgrade over #BluetoothLE with Simple Management Protocol... Supported today on @Apache_Mynewt and @ZephyrIoT... Will run on other PineTime platforms too https://lupyuen.github.io/pinetime-rust-mynewt/articles/dfu

#PineTime @PINE64 Owners will soon be flashing the newest hottest FOSS operating systems... Via Bluetooth from their phones to their watches! Here's how it works... https://lupyuen.github.io/pinetime-rust-mynewt/articles/dfu

Learning to sketch #PineTime @PINE64 ... During a stormy lockdown

#PineTime @PINE64 may become the first Smart Watch that lets you switch FOSS platforms easily... @Apache_Mynewt, @ZephyrIoT, #FreeRTOS, @RIOT_OS... Just flash PineTime over Bluetooth from your phone! Now writing the details of this firmware upgrade https://gist.github.com/lupyuen/47f931a3acaad3a1d826c11023114f8b

#RustLang RTFM on #PineTime Smart Watch @PINE64 ... Looks so cool! https://github.com/dbrgn/pinetime-rtfm

Firmware Upgrade (DFU) now enabled on #PineTime Smart Watch @PINE64 ... Just run nRF Connect on your phone... So cool! https://gist.github.com/lupyuen/47f931a3acaad3a1d826c11023114f8b

#PineTime Smart Watch @PINE64 now manages Firmware Images over #BluetoothLE... Thanks to #Mynewt OS, NimBLE stack and Newt Manager yay! https://gist.github.com/lupyuen/47f931a3acaad3a1d826c11023114f8b
