Hi, i'm trying to boot a classic A33 q8 clone with uboot copied in sdcard but nothing happen (not backlight on)

dd if=u-boot-sunxi-with-spl.bin of=/dev/sdb bs=1024 seek=8 on the partitioned sdcard for reference

In my experience the A33 can be a bit picky wrt which sdcards it will boot from. Sometimes simply doing the dd again will help, sometimes using a different sdcard will help.

I try Sandisk ultra 32Gb,Samsung EVO 32Gb, adata 16GB no difference but ok with A13 (and on a33 original android they are correctly detected), i suppose that i can only wait developers make more test with more hardware, if i can help i'm here.

Now i'm on 2016.09-rc2.

Thanks
