How to Make eMMC Pro Read at 4 Bit Bus?

[Jacques2]

How do you set the eMMC program to operate in 4 bit bus mode? I had Data 0 - Data 3 soldered up correctly to a 16gb device, set at 36Mhz, and it still took 7 hours to download the eMMC chip contents. Other boxes in 4 bit mode soldered up to the same device took half that time.

Hi ,

REV1 hardware is not supported 4 bits
Can you send your Box picture to my PM ?

Mh.... how to check which rev of the pcb. We have? Is there a way of doing it without opening the box and invalid the warranty?

REV1 - and new one do not have much difference
4 bits yes , if your box is new REV is about 90mm in size.
Functions everything same no difference

I sent you the box pic you requested. I may have been sent a Rev1 box when I purchased eMMC Pro from GSM, yet the eMMC Pro adapter sent with Rev1 box has connection points to solder up Data 1 - 3, which lead me to believe the box I purchased supports 4 bit bus.

I was unable to find any information on-line that mentions version 1 of eMMC Pro does not support 4 bit.

If it does turn out that I do have a version 1 eMMC Pro box, can I trade this version 1 box in for a version 2 box that supports 4 bit bus?

Can you please publish here the pics of the different rev boards so customers can verify with version they have?

Its just a smaller PCB ,

First Design was based on Prototype and our prototype had a SD Card Slot inside and that card slot had a lot of space wasted , once we removed that space we made it efficient hardware and a lot smaller ,

So only difference 90mm case and taller case .

Both hardware works same nothing different , i will post some pictures later
