XO 1.5 EC dev changelog

1.5 EC development change log

Ver: 1.9.5

Fixes:

• Catch soft off. Soft off is dictated by SUSC and MAIN_ON (SUSB) when the signals go into a specific state it means that the host has turned itself off and the EC should shut down the voltage regulators.
• Fix the polarity of the SUSC high low reporting. It was inverted.
• Optimize the way the SCI timing reporting was happening the numbers reported by tMO now match the timestamps happening from MO L and MO H.

Features:

• Disable sequence warnings fro srec_cat when building the .bin image
• Update the make dev rule so that it copies the test code to 'ec_test.img' in the EC firmware dir.
• Remove code that deals with a register we don't have. Leftover from another code base.
• Compile option to disable timestamp printing. (if you need diagnostic stuff that has to go really fast)
• Rename all the assert/deassert to enable/disable. This makes it so you can search for specific IO ops. Searching for assert_<bla> would also get you deassert_<BLA>.

Ver: 1.9.4

Fixes:

• None

Features:

• General purpose EC timer host wakeups. EC cmd 0x36 takes a signed long value that is the number of ms to wait and then it will issue a SCI 0x01. Allows wakeups with around 8 - 12 ms resolution for about 26 days in the future. (ie 2^31 milliseconds).
• Autowak is synced with MAIN_ON going low to help duplicate a resume crash.
• LiFePO4 debug dumps can now enabled or disabled via OFW.

Ver: 1.9.3 (Unreleased)

Fixes:

• Fix a typo bug that was turing off CC0 rather than CHG
• Clear the 1 wire guage cache values for voltage and current when there is not a respose to a presence pulse.

Features:

• Tweak the power up sequecing state machine to remove the PWR_GOOD state since it was unused.
• Make the POWER_BUT_IN# strobe pulse the same width for both power up from off and for the strobe when power is on.
• Add support for setting the value on the CHGCTL pin so we can test this feature.
• Refactor keyboard and touchpad wakeups so that you can tell the difference between the 2 and don't wakeup on keyboard break codes.

---

Ver: 1.9.2

Fixes:

• reorder the scancode generation table to match the new ordering from the rewritten GetMatrixKeys.
• Modify the polarity of some signals so they don't create leakage in S5
• Reduce the VR_ON to RSMRST# delay to approx 20ms as requested by Beckham Chen @ quanta.
• Fix no low voltage host shut off bug.
• Battery charge taper current tweak 100mA -> 150mA.

Features:

• Refactor 1-w states to break up some of the larger complex states.
• 1 wire state machines are now run every 100ms.

Known Issues:

• Battery debugging output was left enabled if you connect up a battery you will get a dump of various variables every second.
