Missing /dev/ files for GLCD AND CLCD of L137 test code
There is a post in this section of the e2e called
GLCD AND CLCD of L137 at
http://e2e.ti.com/support/dsp/omap_applications_processors/f/42/p/30087/104863.aspx?PageIndex=1
In that post there is a answer from Prathap Srinivas.
In that answer he references a wiki
http://wiki.davincidsp.com/index.php?title=Omapl137_linux_lcd_driver
In that wike there is a slide that shows Software architecture
The second box down from GUI Applications shows a green box that says
/dev/fb0
Likewise the second box down from the Character UI Applications shows a green bix
/dev/da8xx_lcd
Prathap also has posted in

Two .zip folders, called glcd_test.zip and clcd_test.zip.
In the folders is test code one being
glcd_test.c. In that file is a function called glcdtest_open.
In that function it is attempting to open a file called "/dev/fb/0", as in
(fd = open( "/dev/fb/0", O_RDWR ))
also as in the block diagram the second box down from GUI Applications green box that says
/dev/fb0
Likewise in the test code clcd_test.c, there is a function called
lcdtest_open.
In that function it is attempting to open a file called "/dev/lcd_da8xx" as in
(fd = open("/dev/lcd_da8xx", O_RDWR)).
also as in the second box down from the Character UI Applications shows a green box
/dev/da8xx_lcd
I realise the files should be in the host Linux filesys root dev folder...
However, I can not seem to locate / find the files / anyware
on my system, in order to place them in the root dev folder as needed by the executable test code ....
Can someone PLEASE tell me where to find these files needed to run the glcd_test.c test code and or the
clcd_test.c
Thank You.
Brian
