Hello everyone.

The machine I’m working on is Lenovo ThinkPad L13 Gen 2 20VJ (LAR-2 MB 19837-1) with NPCE68BPA1DX.
I’m not able to read/write the chip with SUCCESSOR (using this line LAR-2 KB_pins=36 LEFT DOWN 05MM FLASH=384 JENK=7 TCK=13 TMS=11 TDI=14 TDO=17 (evserv) CHIP=NPCE68BPA1DX)
36 pins, pin 1 kbd, pin 1 PCB.
Tried only with battery, only with USB-C PSU, with both battery and USB-C PSU.

Nuvoton JTAG ID 0xF6543210
Wrong JTAG ID.
Check the settings and ground!
Motherboard is connected and powered?

Any idea? Thank you!

Ok... found the "problem". Laptops need to be fully initialized. So... after i loaded windows and then shut down everything worked ok (battery must be connected).
