The stm32 needs to flash half a page (ie 128 bytes), the current communication protocol is limited to a 64-byte payload for flash write message. The workaround buffers the first 64 bytes to be able to flash a full 128-byte half page.

- EC Lib
This wraps Blizzard driverlib and implements the EC chip interface defined
by Google. See below diagram for architecture.
