Hi all,
I would like to know when will the driver for CIR available for DM816x? Is there any patch for working CIR driver available in GIT/ezsdk ?
I was able to configure and compile kernel of ezsdk_5_03 and ezsdk_5_04 (as per the steps given at http://processors.wiki.ti.com/index.php/DM81xx_AM38xx_CIR_Driver_User_Guide).
When I boot the kernel with CIR support, I get following crash.
lirc_dev: IR Remote Control driver registered, major 252
IR NEC protocol handler initialized
IR RC5(x) protocol handler initialized
IR RC6 protocol handler initialized
IR JVC protocol handler initialized
