realistically, Allwinner A20 is only a 912MHz (!) processor, not 1.2GHz
21:38
<
ssvb >
running it at 1008MHz needs core voltage that is beyond what is documented to be safe in the manual (the manual lists 1.4V as the maximum)
21:39
<
ssvb >
and 1.2GHz is a recipe for trouble, most of the A20 processors are simply unable to run reliable at this clock speed
21:39
<
ssvb >
have you considered Allwinner H3?
21:49
<

ssvb: ok appreciated
21:56

are you using an old and rather convoluted procedure for FEL USB boot, based on the boot0 binary?

ssvb: gtta go out keep writing i'll be back later
21:58

ssvb >
this way you only need a single "u-boot-sunxi-with-spl.bin" file, which is produced by the regular U-Boot build
21:59

there is no need for special 16K stubs and other bits and pieces
22:26
<
ssvb >
the point is that the most interesting functionality had been
*fully* reverse engineered years ago
22:27
<
ssvb >
you are only missing the video encoding functionality and support for some less common media codecs
22:28
<
ssvb >
but the H.264 hardware accelerated video decoding works fine
22:30
<
ssvb >
oh, it had not been ported to the mainline kernel yet, but still you can do hardware accelerated video playback with the 3.4 kernel, using only 100% free software without any blobs
