Hi,

My hardware design is referenced to the am572x_gp_evm_REV_A3a.dsn, and I use SDK Linux-RT 05.01.00.11.

I can't find the dts file like am57xx-evm-reva3.dts, I don't know which dts file I can refer to?

Hello,

You should use:

{PSDK5}/board-support/linux-rt-4.x/arch/arm/boot/dts/ti/am57xx-evm-reva3.dtso

Regards,
Pavel

Sorry, the contents of this file are as follows:

/dts-v1/;
/plugin/;

&mmc3 {
pinctrl-names = "default", "hs", "sdr12", "sdr25", "sdr50";
pinctrl-0 = <&mmc3_pins_default>;
pinctrl-1 = <&mmc3_pins_hs>;
pinctrl-2 = <&mmc3_pins_sdr12>;
pinctrl-3 = <&mmc3_pins_sdr25>;
pinctrl-4 = <&mmc3_pins_sdr50 &mmc3_iodelay_manual1_rev20_conf>;
};

Yes, seems the difference between A3 and previous rev is only in MMC3. See also below files:

linux-rt-4.x/arch/arm/boot/dts/ti/am57xx-evm.its
linux-rt-4.x/arch/arm/boot/dts/Makefile

Pavel
