Message: 52818    the FLAT format is for userspace, not kernelspace ... plus, it's a driver, not a standalone application

 

using -elf2flt or compiling code by hand simply does not make sense at all in the kernel tree

Message: 52822    Thanks Mike,

                      Yes I have to understand the problem.Now I am able to open the ppi1 driver , but  I am not getting any video on screen. I am getting some garbage value on video screen. How can I undestood that ppi1 driver is opened and if ppi1 driver is opened then how can I decide the suitable application code for the ppi1 driver ? May I used the code which display the Bar Pattern on the screen?  Please reply soon sir.
