Hello.

As You can see from your Software log, You have not connected the device correctly or eMMC has HW problems - eMMC size (capacity) can't be 1024.00 MB:

Size : 1024.00 MB

also next sizes are also incorrect:

Erase block size : 0 Kbytes
Boot1 size : 0 Kbytes
Boot2 size : 0 Kbytes
RPMB size : 0 Kbytes

Try to re-solder all wires, make each of them as short as possible (max. 3-5 CM length) and try to connect again. Try to connect the device with higher (2.0-2.4V) Voltage level, try to set different Bus speed values. Also, You can try to remove eMMC from PCB and solder all wires directly to eMMC contacts (or use proper eMMC adapter). If the problem is still the same, probably, eMMC has HW issue(s).
