where do i get support

Question

i set up a account on easy-jtag section of gsmforum and the site will not even allow me to post an introduction post as it says I need to in oder to ask any questions as a newby - so i cannot get any support there

all i want to do is and and write to my bga153 samsung memory chips.

i have tried for a week with differnet memory chips and i can do antyhing.

i feel that some of my hardware i just purchased must be defective.

my last attempt was using a windows formatted bga153 chip that reads and writes perfectly with my sireda bga153 to usb interface adapter. it reads and writes to the chip just fine.

when i move the chip to the bga153 interface and easy-jtag plus box, i get the same errors over and over

i am a board level engineer but do not know your ahrdware/software. the above screenshot tells me thatthere is no vvc or vvcq power and all the dots are red instead of green. am i missing something.

i have about 300 people waiting for me to be able to read and write my images from one chip to another, but i cant do this if your hardware does not allow me to even get going.

please, please help me or point me in the right direction so i can get some support (other than https://forum.gsmhosting.com/vbb/f672/)

not having any instructions at all available anywhere leads me to guess on how to use this hardware/software

thanks, george

 

 

new details: i just downloaded and installed Z3X Easytag EMMC file manager and it shows that there are shorts on VCCQ pins:

DO I HAVE BAD HARDWARE?

 

 

My Sireda eMMC to USB adapter has pin 1 on to right corner, just like easy-jtag eMMC module

again, chip reads and writes perfectly with eMMC to USB adapter, but not with easy-jtag adapter

i am lining up the chip with dot on top right corner realted to pin 1 postion on both readers (top right)

If work via isp connection - all works fine?

---

i have tried in every mode:

ISP

ISP/highpower

e-socket

ufs

 

all with same results

nothing works, no green dots, no vcc or vvcq power

---

Im not asking about mode that you svitching in software. If use isp adapter like this: https://m.media-amazon.com/images/I/61Ro2xqtnPL._AC_SL1057_.jpg

and solder wires directly to phone mother board - in this connection mode (isp connection) you able to detect ic?

---

oh, ok. now i understand (what isp means)

no, i have the isp boards that came as part of the easy-jtag plus kit

it was never my intension to use ISP boards with a phone, i only needed/wanted to use the easy-jtag plus box with the bga153 chip reader adapter that i also purchased

i have the above errors with or without the bga153 adapter connected.

i am thinking that I have a defective box

your thoughts?

thanks again for taking the time to help me with this, much appreciated

For getting 100% correct answer - you should check connection with another 100% working socket or try to connect emmc via isp.

---

ok, thank you for all of your support
