EC 4.0 Firmware


Jump to: navigation, search


Ver: 7 0.5.01

Ver: 7 0.4.12

  • 0.4.12
  • emit a new event when the power button is released, so a kernel can time the press.
  • increase the hard powerdown button press timeout from 2 to 5 seconds to give user-level more flexibility when looking for long presses.

Ver: 7 0.4.11

  • 0.4.11
  • reinit AC detect timer when leaving forced discharge mode, to avoid erroneous low-battery power-downs. this mode is only during testing (runin, and battery-capacity tests).
  • this release didn't make it into the next release of Open Firmware, Q7B37. --Quozl 01:35, 26 February 2014 (UTC)

Ver: 7 0.4.10

  • 0.4.10
  • Fix for #12704, which caused the power LED to behave incorrectly after short resumes.

Ver: 7 0.4.09

  • 0.4.09
  • Reduce post-reprogramming power draw. After an EC reflash, an extra flash of the LEDs will be seen the first time the laptop is powered off while on battery only.

Ver: 7 0.4.08

  • 0.4.08
  • Change runin discharge disable so its ahead of poweroff
  • Fix stupid mistake in commit b7e7fd817c86

Ver: 7 0.4.07

  • 0.4.07
  • NiMH charging in very cold temperature tweaks
  • Disable the 2 stop mode problem checks
  • Reduce stop mode power draw

Ver: 7 0.4.06

  • 0.4.06
  • Allow monitor DEBUG_CMDS to enable support functions
  • Drop max LiFe charge rate to 2.5A
  • Fix runin discharge XO-4 C2 crash
  • ec_irq: add support for suppressing the fallback pulse, for debug
  • ec_irq: move the remaining EC timing support from monitor.c to ec_irq.c

Ver: 7 0.4.05

  • 0.4.05
  • debug support for wakeup issues

Ver: 7 0.4.04

  • 0.4.04
  • further changes for managing keyboard and touchpad flow control, fixing yet another lockup-on-resume scenario.

Ver: 7 0.4.03

  • 0.4.03
  • fallout from the changes in 0.4.02 caused keyboard and touchpad flow control to not be asserted in some cases. this in turn caused SoC lockups on resume from suspend.

Ver: 7 0.4.02

  • 0.4.02
  • fix EC/SoC communication problems (#12525).

Ver: 7 0.4.01

  • 0.4.01
  • further lengthen EC_IRQ# timings for 1Ghz machines

Ver: 7 0.4.00

  • 0.4.00
  • Fix trac ticket #12558. Power LED while system is off
  • disable the "rescue" EC_IRQ# assertion

Ver: 7 0.3.13

  • 0.3.13
  • revert wakeup timings to 3.0.11 values

Ver: 7 0.3.12

  • 0.3.12
  • ec_irq: add fallback to bail us out of incomplete suspends
  • ec_irq: implement timing tuning commands in monitor

Ver: 7 0.3.11

  • 0.3.11
  • Allow battery debugging to be enabled via serial port
  • Fix incorrect battery critical LED state
  • Change W to mW in battery debug output to make the scale clearer
  • Add debounce for the thermal alarm signal and enable a new LED state when triggered. (Alternating power LED and red battery LED)
  • Blink code for high battery current prior to stop mode (Alternating Green/Yellow)
  • Blink code for exiting stop mode while power is off (Alternating Green/Red)

Ver: 7 0.3.10

  • 0.3.10
  • Fix NiMH pre-maturely marked full problem

Ver: 7 0.3.09

  • 0.3.09
  • Fix logic bug in ext power detect after runin discharge. Machines turning off runin discharge could fail to sense external power.
  • Print ACR value and SOC when going into stop mode
  • Refactor critical and low flag handling to fix corner cases. There were several corner cases where you could get the previous code to display the wrong LED state.
  • Add support for GP LiFePO4 batteries. There are few around the Twine offices.
  • Turn off battery state debugs in LiFePO4 code
  • kbdwatch: wait longer after seeing SOC_SLEEP to release flow-control. Fixes a lockup on 1Ghz MMP3.

Ver: 7 0.3.08

  • 0.3.08
  • Make sure full flag is clear when SOC is < 95%
  • Up bad ACR read difference threshold to 20 counts
  • Come out of stop mode once in a while, to do housekeeping
  • adjust the timings for the EC_IRQ assertions

Ver: 7 0.3.07

  • 0.3.07
  • Check battery EEPROM bank 0 values and fix them if wrong
  • Detect bad ACR register reads from the battery due to ESD and discard them
  • Generate 2 wake up interrupts to the SoC on resume. One to make it wake up and then a 2nd to actually make it start executing. Works around resume problems.

Ver: 7 0.3.06

  • 0.3.06
  • Change battery over temperature indicator to be a pulse of dark (both LEDs off) rather than a pulse of red. Red is now exclusively for errors.
  • Fix typo in IO map causing LV_SET code to mess with EC_IRQ.
