EVM8148 CIR problem

This question is not answered

Hi, we are developing on EVM8148 board and trying to enable  consumer infrared (CIR) driver in Linux kernel.

We have followed the instruction  on TI wiki:

http://processors.wiki.ti.com/index.php/DM81xx_AM38xx_CIR_Driver_User_Guide

But while kernel booting, we got null pointer issue:

"Unable to handle kernel NULL pointer dereference at virtual address 000003f9",

It seems the option "<*>   Homebrew Serial Port Receiver" cause the problem.

Does anyone has any idea of this?

Thanks in advance.

Regards

Po-Lun

    Support for CIR driver is not currently included in the PSP release(hence the under construction banner on the TI wiki page). We are in the final stages of testing this code and will make it available on external kernel staging area(http://arago-project.org/git/projects/?p=linux-omap3.git;a=summary) shortly
