I have this error with all my SD.
All SD I try works fine on pc.

ok, try lowering the frequency (CLK), or trying with a little more voltage.

Best regard.

SD card I/O must be set to 3.3v.


So, set VCCQ to 3.3V, make sure there is ground connected and wires aren't too long.
It should work fine at 2.5MHz with good connection and evenly long wires.

my configuration and mod Riff Boxx v1

Many thanks Mr. Legija,
I tried to set VCCQ to 3.3v as you said.
This is my log and photos of my modified box.

green wire is VCCQ.Where I must connect it on SD?.

Many Thanks,

Box modification is not done according to our officially released instructions and pinout.



You should remove all the wires soldered there, disconnect any externally connected resistors/wires from RJ45 connector pins. Some of pins there are directly connected to box CPU and you can burn it by doing things not approved by us.


Connect VCC to point "A" and route it as wire from box.
Connect VCCQ to point "B" and route it as wire from box.


For SD card direct connection there is no need for pullup and VCCQ.

estore my box

Ok Mr. Legija,
I will immediately restore the box as it was at the beginning, but should the tracks that refer to the nomenclated components R37 and Q2 be cut?

Many thanks for your helpfull.
Best regards,
LuFlavio

Restore done

Hi Mr. Legija,
I restored the box to the factory origins. I rebuilt the two tracks that I had interrupted referring to the R32 and Q2 components.
Here are the pictures:

Restore track for Q2

Restore track for R37

VCC and VCCQ connections
P1020561.JPG

Nothing is changed.
Box reads informations of SD but gives me error as before.


Please can you tell me the list of pins to connect to Sd?
Where do I connect the VCCQ pin?

Many thanks,
Best regards,
LuFlavio.

Solved!!!

Dear Sir,
I have solved soldering VCCQ instead of VCC on SD card,then I adjust frequency to 960KHz and VCCQ voltage at 3.30V.


Many many thanks for all.

I hope this thread can help the others


Many thanks,
Best regards,

ISP adapter

Mr. Legija,
I'd like to ask you one last question
I built the ISP adapter following this scheme, but when and how should this adapter be used?

You can use it with all devices.
