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

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
