I suspect that the SDRAM setup is non-optimal. The symptom is that
|

writing into frame buffer (in SDRAM) occasionally corrupts the DMA
|
||||
descriptors (also in SDRAM) When the bad DMA descriptors are
|
||||
fetched, the channel shuts down and the display goes black. This
|
||||
problem could also be cause by a bad write outside of the framebuffer,
|
||||
but was not the case in the few examples that I studied.
|
||||
problem could also be cause by a bad write outside of the framebuffer
|

and, in fact, putting a guard band around the framebuffers seems to
|

eliminate the problem.
|

c) There are some occasional start up issues. It appears that the LCDC
|

is programed incorrectly and groups of pixels in the images are
|
||||
reversed (producing an odd serrated look to the images).
