Hi,
I checked in a package that can be included in bootloader, and
it will accept image upgrades over serial port.
It expects that the image upgrade is done using the newtmgr
protocol. Command set that it supports is limited; it can list images,
accept an image upload command (stores it to slot 0), and also reset.
For testing, I added a snippet of code to apps/boot which can
be conditionally compiled in by defining target features for boot loader
to include BOOT_SERIAL.
The code monitors a GPIO pin, and if it’s set to specific state during
bootup, it’ll enter the serial downloader, awaiting these commands.
Again for testing, I added the pin config to use for Arduino MKR1000
BSP.
Here’s my target definition for using this, in case you want to try this
out:
[marko@IsMyLaptop:~/src/incubator-mynewt-blinky]$ newt target show boot_mkr1000
targets/boot_mkr1000
app=@apache-mynewt-core/apps/boot
bsp=@mynewt-arduino-zero/hw/bsp/arduino_mkr1000
build_profile=optimized
features=BOOT_SERIAL
Feedback appreciated,
M
