Hi!I tried to read and write a 16Gb emmc on socket.But problem is that the estimated time is 5 hour.
Look at log .
Max speed is about 970Kb/s and in isp mode is same .
Can tell me anybody where is problem?Hardware, maybe my box?thanks!
On socket i never read before ....This is first time.
the emmc is new.
Tried 2 laptops with win 7 ,32bit.

It's a native very good socket
It's a strange problem

I sent my box with my emmc ,emmc socket,usb cable to a friend who tested my cable ,my socket with my emmc .He has another easy jtag plus box but his working properly.
He is reading with 12433kb/s and my box is reading with 990kb/s the same emmc with same emmc socket adapter,on same laptop.
It seems my box is defective.
Somebody know what is the problem or how to fix it?Thanks!

Thanks for the reply ,maybe you are right,but as i say i sent my box to a friend and he tested with another laptop and also same problem.So usb port

is nothing do with my problem.
Question ,if i have the Z3X v1.0 6in1 socket for emmc


look here: https://ibb.co/wL50SV2 ,must connect directly to my box or must use the e socket adaptor?
like this:https://ibb.co/Vg8DBjR


Thanks!

if you solved this problem this device can perform faster if conect to high speed usb port



then your all problem solve about speed


check usb port clean it or check from motherboard



and don`t search any other solution for speed

I can assume that this is a possible low-quality manufacturing of the box board at the factory. here is the option to send under warranty or try to solder the main 2 chips in the box.

Thanks again but in my friend laptop not appear this message ,and still not read just in low speed as i say.And my friend box read OK.understand now?
The message appear only in my laptop.that's why i send only box to my friend to test it.

Hi! I solved this problem:this device can perform faster if conect to high speed usb port
This message not appear anymore,and problem was in my box.User Sneha was right,but problem is not the usb port,i cleaned contacts .I resoldered the 2 chip pins with hot air station.No succes.
How solved?
I buyed another box without card and i put card from old easy jtag plus box to new one.
as i say no message appear and speed is now aprox 24000 kb/sec.
But the big question what is the real problem in my old box??
Only the manufacturer can tell me....
Thanks anyway to members who helped me.
I am still wondering what is the real problem with my first box.

Hi again!
I found the problem in my first box.
The rezistor R9 is missing!!!
I measured in new box and it is 6K8 .
I put 10K for test and it seems to be OK!OK!OK!
So no more message appear!
Maybe help someone else!
