New BGA 162 eMMC from BIWIN
 

Hi,
the emmc made by BIWIN, marked BWS32AH5 C+2L.
Tried to connect as common bga162 pinout, with pullup to 1.8V, still get CMD Timeout Error.
Is it not supported by EasyJTAGPlus yet or am i doing something wrong?

add capacitor to VDDI pin
if connection is ok - you eMMC may be dead

biwin has mcp packaged as bga162, if you have rom try to check scatter for more info

Capasitor is already on the pcb. eMMC is not dead, phone operates just fine.


Any other idea?

if you connect to board you need use HiPower CLK mode

scatter is for MTK, i have SC9820E (Spreadtrum)

I've tried with usb power, with external power supply, still cmd timeout.

i think it isnt emmc, it's nand mcp.
if you use easy-jtag plus with nand socket, you can try with this pin out.

cNAND is more likely, but it's size 512 and using socket EasyJTAG is not able to identify chip. I could try to use custom layout, but can not find datasheet for page size, peges per block etc.

any other idea how to get dump for this case?

BGA162 NAND adapter (limited release)

Thank you.
I have NaND Adapter, can i use direct pinout to connect to it, instead of using soldering adapter? What pins should be connected?

If you want to connect it - you need use wires.
Name of pins is marked at PCB of adapter (you need connect ~20 wires)

how can i order soldering adapter?

in this case, the shipment and the fee itself will be expensive, so they were released in a limited edition for those who ordered. if you are satisfied with the price around $ 15, then we will try to send you
