A2 Prototype
Ver: 0.0.9
Download: 0.0.9
- reset keyboard module state when powering up the board
- add quick blink when power button has been debounced
- add ambient light sensor prototype code (requires custom hardware, or wait for A3)
- implement CMD_POWER_CYCLE
Ver: 0.0.8
Download: 0.0.8
- fix typo affecting initial state of EN_3_3V_SOC
- disable power controls during stop mode (safe, since we know the board is off at this point), to reduce leakage
- add git hash to version info
- fix handling of uppercase hex digits in tohex(), and "make format"
- disable more internal clocks, guided by new EnE docs
- add CMD_RESET_EC and CMD_RESET_EC_SOFT protocol commands, for resetting the 8051 core, and the whole chip, respectively.
- add 'r'eset command, and rearrange watchdog exercise commands.
- use internal oscillator for watchdog, so it runs in stop mode, and add watchdog_reboot() routine.
- fix bug in enable/disable_EN_SD[12] macros
- turn off trim_tune() debug output, and enable stop mode.
- turn off stop mode debug output
- disable the spi host controller in powerdown state, to reduce leakage.
- add commands for more watchdog control, for debug
- reintroduce failsave recover loop at top of main.
- configure the EDI CS input to wake us, so we can program the EC when in STOP mode.
- make the AC input wakeup work, by switching to edge-triggered from toggle-triggered. toggle-triggered should have worked.
- get rid of extra wakeup PF flag, by setting GPIO2D (TP167, used for the gpt3 timer output heartbeat) to output-only. also ifdef the stop-mode debug code. AC jack wakeups are still disabled.
- Add delay prior to entering stop mode.
- Make main_io3731 the default main.c via symlink
- fix initial copyright

- Enable board ID reading
- Wait for the flash trim read to complete before reading the data
- Fix battery error LED state not set on battery error
