CPU power supply controller MP2949A programming with MPS EVKT-USBI2C-02

Model: Asus UX461U
Motherboard: ASUSTeK UX461UN, Rev.: 2.1
CPU power supply controller chip PU8001: MP2949A

Hello!

I want to read a dump from the CPU power supply controller chip located on the mentioned motherboard using the MPS EVKT-USBI2C-02 interface. The motherboard is fully functional.

I downloaded the "GUI tool" from the link in this post and installed it, but when I click on the "Scan" button, it throws me the message "MCU Code: Unknown!".

I connected the SCL and SDA pins of the EVKT-USBI2C-02 interface to pins 27 and 28 of the MP2949A chip. I also connected the ground between the interface and the motherboard and pressed the "Scan" button when the laptop was turned on to the BIOS screen.

The EVKT-USBI2C-02 interface is detected by the "GUI tool", but I get the same message if nothing is connected to the SCL and SDA pins of the EVKT-USBI2C-02 interface.

Any idea where the problem could be?

I found the problem myself.

matic napisal/-a:I connected the SCL and SDA pins of the EVKT-USBI2C-02 interface to pins 27 and 28 of the MP2949A chip.

I connected the EVKT-USBI2C-02 interface to the SVID BUS instead to the PM MUS...
The correct pins are 32 and 33 of course. Everything works now.
