Combo sensor in MIMXRT1020-EVK

I tried to test the examples provided by the RT1020 SDK, to make use of the FXOS8700CQ sensor (accelerometer, magnetometer) of the MIMXRT1020-EVK evaluation board. The program gives an error message at runtime, there is no communication with the chip U26 (the referred sensor).


Today I have been looking at the board, and the problem is that it does not install that chip (U26), although it does appear in the scheme.

Is this normal, are there several versions of this board, with and without this sensor installed? On the RT1050 evaluation board, this sensor is installed with reference U32 of the diagram, but it is missing on the board of the RT1020 (U26).


I have three more MIMXRT1020-EVK boards, and all are without the U26 chip.  I will try to install it by myself, if I can locate the chip in a distributor.
