@Lwasserman Just think... Any gadget with an SPI port can become an SWD Programmer now... Laptops, phones, all kinds of microcontrollers too!
Woke up in the middle of the night and realised... SWD consists of only 3 bit sequences: 1️⃣ Read Register 2️⃣ Write Register 3️⃣ Reset... So why not connect the SPI port to an FPGA to trigger these SWD bit sequences? 🤔

A cheap #FPGA can convert a standard SPI 4-wire interface into an SWD Programmer... I think 🤔 https://medium.com/@ly.lee/openocd-on-raspberry-pi-better-with-swd-on-spi-7dea9caeb590?source=friends_link&sk=df399bfd913d3e262447d28aa5af6b63

We're now building the open source #PineTime @PINE64 Companion App for Android on iOS, based on #Flutter... Here's how we converted the #BluetoothLE code from #GoLang to #DartLang for the Flutter app https://lupyuen.github.io/pinetime-rust-mynewt/articles/companion
@hilaire@pouet.chapril.org @PINE64 Oh and Pinebook Pro doesn't have a touchscreen. If you need one, maybe the upcoming PineTab is better https://www.pine64.org/pinetab/
@hilaire@pouet.chapril.org @PINE64 Yep the choice of operating system matters too... @ManjaroARM with #Xfce feels so much more responsive than Debian Mate that I have been using
@danslerush @proto_azure I have friends from Microsoft on LinkedIn... So shhhhh ;-)
Linux Mint 20 will block Ubuntu Snap by default - gHacks Tech News
4K TV 65-inch with @ManjaroARM #Xfce on #RaspberryPi 4... Looks stunning wow!
@ManjaroARM Honestly I was surprised that Manjaro Xfce doesn't have the bugs I saw in Ubuntu Desktop 20.04 64-bit on Pi 4...
(1) Ubuntu doesn't detect the onboard Bluetooth hardware.
(2) Ubuntu Desktop can't switch display resolution (forced to run at sub-1080p resolution).
(3) Ubuntu display driver renders black blocks sometimes.
Great job @ManjaroARM !
@hilaire@pouet.chapril.org @PINE64 Pinebook Pro runs on big.LITTLE architecture: Dual Cortex-A72 + Quad Cortex-A53, 64-bit CPU. Total 6 cores :-)
@ManjaroARM Seems OK so far. Managed to install packages over WiFi without problems. There was some screen flickering, maybe that's my faulty HDMI cable

Oops my mistake... I selected 4096 x 2160 resolution. After switching to 3840 x 2160, it's a lot faster now
