Allwinner A10 anycast hdmi dongle

[Dev_on]

Hello sunxi people!

This is my first participation in this group.

I've bought an Anycast HDMI Mircast dongle a while ago. I cracked it open and found out it's a rockchip rk3066 (or is it?).

So i did a research on google and found this it's the same board the PCB is red, has a text label SP-X11-V2.0, everything is the same. What's diffrent is the markings.

So my main question is, Why the marking is faked? (Atleast on the Allwinner A10 chip), And how do i dump the firmware?

 

I am not a linux dev, I am newbie in this kind of thing.

(Note: Sorry if there's a mistake on my writing, english is my secondary language)

Thanks!

If you opened it and found a Rockchip SoC instead, you should probably
head over to linux-rockchip?

It could genuinely be a Rockchip SoC. Vendors can redesign products with
whatever components they have on hand.

I once bought a Q8 tablet expecting an Allwinner chip inside, only to get
one with an Actions Semiconductor one instead. I returned it.

If you can get some sort of system information screen on in the existing OS,
it should have some sort of hint. Like the kernel version string might have
some vendor suffix.
