Hello.

Please carefully check soldering of all eMMC wires accordingly to the pinout picture, most likely some wires are soldered incorrectly or maybe You've made some shorts on PCB while soldering. Also note, You should disconnect battery and USB cable before connection the device, this is important.

And post here full Software log, not reduced.

i do check all soldering and check again and again but same

the mmc is

KLMAG2GE4A IS THIS SUPPORTED IF YES WHAT THE PROBLEM

I NEED HELP WITH THIS PROBLEM

BEST REGARDS

Most likely, the problem is with connection. Please make photos in high quality of how You soldered each eMMC wire and post them here, we will check.

It is not clear from these photos whether You have soldered all wires correctly. But we can see, that You have soldered wires too long, please re-solder carefully all wires as short as possible and try to connect again. Also please use thin wires, which go with Medusa Pro Kit.

I did all thing same problem jtag on octopus box working good

Possible reasons why the device don't connect:

1. You have connected battery or USB cable. Before connecting the device You must disconnect the battery and the USB cable, and then connect the device without power, this is important!
2. Some wires are soldered incorrectly. Carefully check soldering of all wires.
3. In the process of soldering, the resistors were burned (damaged) by using soldering iron or the pin pads on the board to which wires were soldered were damaged. Need replace damaged resistors and restore the pin pads on the board.
4. The ends of wires that were soldered, had not been cleared. Wire, that comes complete with Medusa Pro Box, is covered with an insulator, so before soldering need to clean the ends of each wire.
5. Soldered wires are too long. Make each wire as short as possible.


Also, please make one photo (or scan) in high quality, where will be clear vissible of how You have soldered each wire on PCB and to eMMC adapter.
