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?
