>
> The majority of err about cannot boot, we've still not fully understood yet.
> I made two mistakes on BoM value which let VGA DDC failed and R30/R39
> swapped. You can check it out. Now for all of those batches I fixed back.
> The Y2 Xtal for video chip I just requested samples from the same type of
> Y1, later I'll test this.

> Most of this run we have productive items needed to improve:
> 1, checking incoming parts' mark/pins
> 2, good results of AOI and visual inspection
> 3, well-defined on audio test environment built
> 4, use a Y Pb Pr component video in signals rather than one composite PAL
> video in
> 5, fast flashing
>
> I just roughly mentioned them above, if you think it's not enough, just
