A3 Prototype

Ver: 0.0.11

Download: 0.0.11

Ver: 0.0.10 (never released)

  • fix GPWU register save/restore
  • don't clear the ADC interrupt flag
  • update ambient light sensor pins for A3
  • add A3 board id
  • new charger chip support
  • solar maximum power point tracking merge from XO-1.5

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

Ver: 0.0.7

  • Internal non-released test version.

Ver: 0.0.6

Download: 0.0.6

  • Fix touchpad

Ver: 0.0.5

Download: 0.0.5

  • Initial cut at adding stop mode. disabled by default for now.
  • fix the clearing of the power-off command flag
  • Shorten the cycle_led times.
  • add a bunch of debugging output for the trim registers
  • add io support for the RESTORE pin, and an sfr for the PCON register. also formatting.
  • 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

Ver: 0.0.4

Download: 0.0.4

  • Enable battery charging
  • Implement api for poweroff add debug code for showing power states.

Ver: 0.0.2

Download: 0.0.2

  • Enable/Fix EC<->Host communication
  • Enable/Fix Keyboard stream.
