EC 1.75 Firmware

B1 Prototype

Ver: 0.1.03

Download: 0.1.03

• Decrease the OLS sample rate to 500ms
• Rework the OLS SMT test for OFW control
• Make B phase boards no-op the KBD power GPIO.

(Also functions on A3).

(Incompatible with A2, causes excess charge voltage).

• Report power button presses to the soc via an event
• Make keyboard/touchpad debug output runtime controllable

Ver: 0.1.01

Download: 0.1.01

• Keep OLS LED from blinking
• Fix small error in keymaping for mechanical keyboard
• Rename ALS to OLS per wad's request

• notify the kernel when we artifically disable charging
• implement a new upstream channel for command error reporting
• implement support for battery status event reporting
• implement SOC change event reporting
• fix AC status change reporting
• fix event reporting for abnormal battery conditions
• Add keymapping.csv into reppository

Ver: 0.0.11

Download: 0.0.11

• fix missing battery current in mA calculation
• reduce nominal input power to about 18 watts
• fix sporadic ISL communication errors
• fix MAIN_PWR to VCORE enable timing
• drop I1 from mppt debug print
• add EC cmd to get the EC version hash
• ambient light sensor support
• fix CHG statement in LiFe debug print
• fix missing battery LED state if MPPT stops charging
• add serial EC boot message

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.
