Hi team,

K2H evm have a mcu microchip use spi interface to control some signal of K2H. like below picture.

If my customer didn't use this mcu, how to process those signal(include HW and SW), like SOC_HOUT,SOC_PACLKSEL....

BR,
Denny

    Hi Denny,
    Customer wants to replace with different chip (SPI to GPIO) ?
    These chips were connected to M3S2D93 micro controller via different chip selects.
    Those O/P gpio pins important for powering up the K2H.
    It has been controlled (input & output) by micro controller through SPI0 bus.
    From sw perspective, if you want to change some other IC then you may need to modify the uC M3S2D93's sw code.

    I hope this helps.

    Hello Denny,

    If the customer is not using MCU, then they could hard wire (using logic circuits if required) the required pins on the processor itself based on their application.

    If you would like to know the usage of processor output pins (like SOC_RESETSTATZ, SOC_BOOTCOMPLETE, SOC_HOUT) in the EVM, please refer BMC code in below link.
