Hi, We also have a sysfs attribute in the MV 4.0.1 based LSP 1.20 release for DM355 - /sys/class/davinci_syste/system/reg to read/write to memory mapped registers.
For e.g. echo 0x20000020 0x30 > /sys/class/davinci_system/system/reg Thanks Sneha ________________________________ From: davinci-linux-open-source-bounces+nsnehaprabha=ti....@linux.davincidsp.com [mailto:davinci-linux-open-source-bounces+nsnehaprabha=ti....@linux.davincidsp.com] On Behalf Of Jadav, Brijesh R Sent: Wednesday, February 18, 2009 11:38 PM To: serdar uludag; [email protected] Subject: RE: lcd flicker problem and all of DM355 patches Hi, You can use the utility given at the following location to read/write to any register from application space. www.sleepie.demon.co.uk/linuxvme/io.c<http://www.sleepie.demon.co.uk/linuxvme/io.c> Thanks, Brijesh Jadav ________________________________ From: [email protected] [mailto:[email protected]] On Behalf Of serdar uludag Sent: Wednesday, February 18, 2009 9:46 PM To: [email protected] Subject: lcd flicker problem and all of DM355 patches Hi, I use DM355 and 640x480 Lcd so I have got flicker problem. I changed the UBL code (DDR->PBBPR = 0x00000010 in device.c) for solve the lcd flicker problem. But there is no any change. I think 'writeb 20000020 0 10' command line does same think. But I can't try this command line. How can use this line in my application code or where must i use? Is there any link can I find all of DM355 patchs? Thanks
