iif I remember correctly there are only one or two GTA04A3 boards where the LIS302
was installed. So a driver was never developed for it and all others have a BMA180.

try i2cdetect -y -r 2

the LIS302 responds on 0x1c or 0x1d
the BMA180 responds on 0x41

i2cdetect will report a UU if a driver has been registered for that address.

Alternatively you can go into the U-Boot console and run the


command. It will print all the I2C devices it finds.

The LIS302 in the GTA04A3 design is exactly an LIS302DL(TR). Please note that there are different LIS302 chips...

This driver appears to be the right one (at least it mentions the LIS302DL):


So I think you need:


That essentially confirms what Lukas has written (see below).

In addition, you will have to add an entry to the board file to provide the correct platform data.
