Since this is a merged firmware, you need to use esptool.
python -m esptool --chip esp32s3 --port <COM PORT> --baud 1500000 --before default_reset --after hard_reset write_flash -z 0x0 .pio\build\bootloader\bootloader.bin 0x8000 .pio\build\m5cardputer\partitions.bin 0x10000 .pio\build\m5cardputer\firmware.binmake sure to replace <COM PORT> with your cardputer serial port.
flash binaries from SD with
flash /path/to/binary.bin
then launch it with
launch
create aliases for flashing and launch: e.g. shortcut flash and launch bruce as "br"
alias br "bruce /binaries/bruce.bin && launch"
commands can be viewed with help
display can also be controlled with Fn + _ and Fn + = for dimmer and brighter display. also Btn0 toggles display to save battery
edit (filename) to enter nano-like editor
Fn + , . / ; for left down right up
Fn + backspace for exit/save. moves to status line and prompts directory to save and filename. enter to save Fn + backspace to discard
Fn + C copy line
Fn + V paste line
Fn + X cut line
- fixed an issue where having a LoRa Cap (or any Cap on that matter) interferes with reading the SD on boot
- updated UI
- added a nano-like text editor
- probably final update as no other features are planned
- nvs gets overwritten every time a firmware is being flashed. this was on 1.7 when i added functionality to name what firmware is inside ota_0 by writing it in nvs. it is also where the aliases are saved. fixed it by moving those to SD (firmware name and alias). because who would use this firmware flasher and file manager without an SD right?
- Public release
- GitHub repository created
