KCU105 System Controller display wrong name of "KCU1250" or "UNABLE to determine board type"

Jump to solution

Hi,

I bought 2 KCU105 evaluation board, when I plug mezzanine card on them, the VADJ_1V8 power supply remains 0V. So I connect the System Controller through serial port to set the VADJ_1V8.

However I found 1 board display that the board type is KCU1250 and there is not command option to set the VADJ_1V8, see the following screen shot:

And the another board display that "UNABLE to determine board type from EEPROM" and ask me to set the board type and revision, see the screen shot:

Problem solved.

It is because the mezzanine board and the reference design with it has some problem and reset the I2C multiplexer.
