Hello, As we have to develop framebuffer for i.mx6. We were referring materials regarding i.mx6 framebuffer. We gained some knowledge on how to deal with this but we dont know from where to start. Can you please guide us??
from the Reference Manual, which should be a good starting point for you, I could see that the IPU (image processing unit) within the i.MX6 SoCs seems to be the same, or at least very similar to the one within the i.MX53. A driver providing limited functionality of the IPU can be found in Genode's os repository [2]. The driver however does not implement the whole operation modes of the IPU, but was developed using traces regarding I/O memory access of the corresponding Linux kernel driver, the same approach Martin Stein explained in a previous mail. Nevertheless, that code might be a good starting point too.
Regards Stefan
