How to use the gamma correction for i.MX6UL

Dear all,

 

We want to make gamma correction in i.MX6UL.

We understand that we have to use the PXP_LUT_CTRL and the PXP_LUT_ADDR registers.

 

However, We do not understand those how to use.

 

Would you tell me how to use the gamma correction by using these?

 

 

IMX6ULRM.pdf(Rev0):

http://cache.nxp.com/files/32bit/doc/ref_manual/IMX6ULRM.pdf

- 40.7.37 Lookup Table Control Register. (PXP_LUT_CTRL)(P.2420)

- 40.7.38 Lookup Table Control Register. (PXP_LUT_ADDR)(P.2422)

 

 

We referred to LinuxBSP.

BSP: fsl-yocto-L3.14.38_6ul-ga.tar.gz

 

However, We were not able to find these cords.

Would you send it to us if a sample source code exists?

 

Best Regards,

Yuuki
