EasyJTAG box (color box) pinout

To get 1,8 & 2,8 you need use adapter

@gunit1: Which picture? You probably forgot to attach it.

@layder: Which adapter do you mean? Easy Jtag adapter ? I saw a different EasyJtag emmc pinout from yours. How did you get yours? Are there really so many clock signals coming out from EasyJtag emmc pinout?
Besides, from your picture I cannot see how to connect yellow wire/pin marked VCCQ=VDD
Thnaks for the replies

old (EasyJTAG box, not EasyJTAG Plus box), is have only GND, CMD, CLK, Data0 pins. Box is requires external 2,8 & 1,8v supply eMMC power (from USB adapter), or need "Hipower CLK" conection, when power to eMMC used via board from USB power connected to it.

"HiPower CLK" mode is requires connect 4 wires CLK from box together.

VCCQ - 1,8v
VCC - 2,8v

Color cable for JTAG connection

I tried to use EasyJtag with EasyJTAG power adapter to program eMMC on Samsung N8010( tablet). But I failed.




It seems to me as if EasyJtag could not see eMMC( maybe because of a faulty EasyJTAG power adapter) or an error of EasyJtag itself.
Can anyone give a clue what to check? What signals should I see on CMD pin( and other pins) with an osciloscope?
Thanks

You need check connection lines CMD, CLK, Dat_0 from box to eMMC, you need check voltage on eMMC power pins. If you use ISP connection, you wiil try to select 2,8v at software (for 1st box generation).
