Developers (Advanced)
Development Environment
BlueSCSI v2 uses PlatformIO as it’s dependency and build tool. You can install the PlatformIO IDE or use the PlatformIO Core CLI to build BlueSCSI.
PlatformIO IDE
Install Visual Studio Code or VSCodium.
Clone the BlueSCSI-v2 git repo and open the cloned folder in the IDE.
You will be prompted to install PlatformIO - follow the prompts to install the PlatformIO extension.
Run the “Build” task.
Flash the the .pio/build/BlueSCSI_Pico/firmware.uf2 file to the Pico following the flashing instructions.
USB Serial Debug
Connect the Pico via USB to your computer. Use a terminal program like Tera Term (Win) or CoolTerm (Mac/Win) to view real time logs from the Pico. Note the first logs may go by faster than the USB Serial starts. You can start with the SD Card out then insert it to see the config log.
Setting up PicoProbe
Analyzing Crash
arm-none-eabi-addr2line is needed and not installed by default on PlatformIO.
# Mac
$ brew install gcc-arm-embedded
# Usage:
# utils/analyze_crashlog.sh # paste log to console, press ctrl-D to end
# utils/analyze_crashlog.sh log.txt # read log from file
# utils/analyze_crashlog.sh log.txt path # read log from file and find firmware at path
Release
- On
maineditsrc/BlueSCSI_config.h- set the date andrel, commit and tag, egv2024.09.15 - Edit
src/BlueSCSI_config.hback to date + 1 anddev - Push tag
git push origin v2024.09.15 - While action is running, create a release off the tag (GH Action should really do this itself)
- Generate release notes, note any commits or PR’s.
- Once action is done and notes updated push main.
List of SCSI Commands implemented
