hi

[ching_gsmX]

but i also tried wire only and use only the 3.3v and 1.8v from adapter same result

[ching_gsmX]

thankyou for the reply i tried again with shorter wire and swap the vcc vccq because vcc have 1.8v only and vccq have 3.3v so i swap the supply and
shortened the wires and bingo!! it detect!! it was adapter fault.

CMD Active Level: 1402 mV
Can't init device. Reason: CMD Timeout Error"

i put pullup resistor but same

same to ching_gsmX i cut the jtag wire to shorten but i'm not lucky as ching_gsmX

any one cane gave exact solution to our problem

thanks

hi.. mr. kratos
I think it's may either wrong pinout or dead emmc
try following may help
1. plug device battery and hit power button... check VCC and VCCQ shown in pinout image... if it's righ pinout must be VCC around 2.8 - 3.1V and vccq around 1.8v . this is for make sure vcc and vccq are not reversed.
if it's not helped. go on to following.
2. Keep plug in battery and USB , unsolder VCC and VCCQ wire from board.. check Hi-power clock drive mode option. try to init emmc... not helped too? next..
3. Using two 100R resistor and connect to 1.8 Volt and CMD and D0 each.. init emmc and try to switch eMMC voltage in software... if not working try to connect resistor to 2.8v instead of 1.8

Hi everyone. I got easy jtag currently... And I got Can't init devices, reason CMD time out error. Plz help. I'm trying to repair boot of I8200... But I didn't get connection between cell and pc

[layder]

1) check connection, exc
2) try to desolder eMMC and check it at socket - it may be dead and need to replace
