ATF team, please, post list of supported eMMC

H9DP32A4JJAC not support?

VCCIO 2,8- 3,3v - some results
IC normally detect at u8815 via RIFF

For those like me that bought GPG ATF 5in1 cable.. i don't know what they had smoked but the connection is completely different !

This is the pinout provided by lalitjsraks (the correct) :

pin 2- 2.8v vddf
pin 5-blue cmd
pin 6-red clk
pin 7-brown gnd
pin 8-green data0

And this is what i’ve found inside gpg cable, coming from RJ45 , i had to open it losing my warranty because i never received support from GPG team.. very bad !!

pin 1 (white) - 5V usb (used to make 1.8v and 3.3v) AND cmd !! oh my ***
pin 2 (red) - not connected, cable CUT
pin 3 (yellow) - clk
pin 4 (orange)- jtag TDO
pin 5 (green) - data0
pin 6 (black) - jtag TCK
pin 7 (brown) - gnd (wow! at least one good)
pin 8 (blue) - jtag TMS

So if you use this cable without modifications, the connection with the emmc doesn’t work.
I don't know also if VCC 5v connected to CMD line can damage the emmc.

If you break this line you loose the 1.8v voltage regulator and you have to use an external power supply. At this point.. it is better to build an interface yourself.

GPG Team please correct me if i am wrong, and supply a decent user manual with your products.

Product fifth grade, very bad, stabilized voltages are not used since no voltage regulators, for example voltage at 1.8V and a 3.3V voltage. Thus there is a high possibility of damaging the EMMC Chip, I had to open and modify the PCB myself adding voltage regulators. GPG Industries anymore.

Please share someone samsung N8000 Boot1 and Boot2 partition dumps.
Maybe exist method to make them from official firmware ?

pls support san.disk, hynix emmc. Thanks

i have emmc chip which is not on pcb. how i can use external power supply? i dont have a emmc socket. i want to solder wires directly to emmc pins.

thx and br

B.R.

to which emmc chip this pinout belongs to? i compared many pinouts but no one matched to this one how it was soldered here..

thx

[layder]

pin 2 - 2.8v vddf
pin 5 - cmd
pin 6 - clk
pin 7 - gnd
pin 8 - data0

1.8v I made from cutted pcd with IC from SE K500 (flash ic power) (power to 1,8v DC converter from pin1 atf box (4-5v)

at my cable red - +2.8v, brown - GND, 2 resistors from 1,8v to data0 - 51kOm, to cmd - 10kOm

I have another eMMC with the same symptom as the nokia eMMC.
This one comes from an i9300. Apparently dead..

I have soldered the chip following the schematics, put 2.8v on VDDF and 1.8v on VDD.

By selecting "Scan Emmc" i got this results :

2. Connect the Soldered TP Connections to ATF Box     
3. Disconnect the USB Cable and Wait until the        
   the ATF Software will tell you to Connect the USB.

It looks like the eMMC is working, but after pressing Read eMMC, it start with a loop of infinite retry, and it does not read anything from the chip.

On ATF Software i have selected 2.8v , 7.5Mhz (also tried 15, 3.75) and 16GB, read user partition, default block size.

What can it be ?? really damaged un-readable chip ??
Thanks for your help

perfected and put in place IC from SE K500 (flash ic power)-ic lm1117-1.8v output. good work i am tested

[layder]

true pinout:

pin 2 - 1,8/2.8/3,3v VDD
pin 5 - cmd
pin 6 - clk
pin 7 - gnd
pin 8 - data0

pin 1 - from 5v to 2,8/3,3v VDDF DC/DC converter

Data0 to VDD - 51kOm reststor
CMD to VDD - 10kOm reststor

do i need to solder pin vddf to pin of emmc when the chip is not on the pcb? i tried without pin1 but emmc cant get scanned. i solder only pin 2, 5, 6, 7, 8 to emmc chip.

i use modified atf lightning dongle. but also if it is not modified the 2.8V which i need is default in this dongle i guess.

can anybody help me?

if you want to connect only to a flash ic, then use the pinout which laid layder

but if you want to connect a flash ic that is soldered on the board, use the pinout
pin 2 - 1,8/2.8/3,3v VDD
pin 5 - cmd
pin 6 - clk
pin 7 - gnd
pin 8 - data0

pin 1 - from 5v to 2,8/3,3v VDDF DC/DC converter

Data0 to VDD - 100Om reststor
CMD to VDD - 100Om reststor

[huzein]

in the last post of layder (#61) he gives the pinout what you describe is for soldering a flash ic when it is on the board.

i need the pinout when the flash ic is not on the board.

[layder]

Pinout for Flash w/o board.
If you solder pin to board, you you need additional power from external supply (VDD/VDDF line may consume more amperage).
At board also exist resistors to CMD/Data0
