Question :

M4 Corresponds to the Relationship Between ma35d1-cpu800-wb-128m.dts and ma35d1.dts


Answer.

"ma35d1.dtsi" determines which ones are used for A35 or M4. If you find the word "SUBM" that means it is for M4.

Please refer to the naming convention:
MA35D1_Buildroot/output/build/arm-trusted-firmware-custom/plat/nuvoton/ma35d1/include/sspcc.h

"ma35d1-cpu800-wb-128m.dts" is the default PIN definition.
For example, UART16 is used for M4 in ma35d1.dtsi

Code: Select all

&sspcc {
        gpio_s = <PD6_S>,
                <PD7_S>,
               <PK2_SUBM>,
               <PK3_SUBM>;
};
