Subject: [PATCH V2 0/3] introduce latmus
Date: Fri, 16 Apr 2021 01:31:30 -0400	[thread overview]
Message-ID: <20210416053133.23412-1-hongzhan.chen@intel.com> (raw)

Latmus is a backport from EVL to Cobalt, the procedure is fully
described here: https://evlproject.org/core/benchmarks/

I verified all functions of latmus on hardware environment under which 
Rock PI X board connect GPIOs with FRDM K64F.But actually Rock PI X V1.4
board's GPIO I/O voltage is 1.8V does not match 3.3V of FRDM K64F board.
Even though I tried to set up IO shifter board to bridge two boards,
still can not get correct latecny data because of bad IO signal. So I
have to work around to loopback Input/Output GPIOs on both boards to do
verify functions.

Hardware setup:

---------------------------------------------------
     eth|                                     |eth
        +                                     +
      FRDM K64F board                   Rock PI X board                  
      |         |                       |           |
      +_________+                       +___________+
