Tool/software:
Hello TI- team
We are using u-boot(2023.04) from SDK9.0 and upgraded the kernel 6.6 and yocto scrathgap.
eventually we will migrate to SDK10 uboot but for now taken from SDK9.
In "arch/arm64/boot/dts/ti/k3-am625-sk.dts"
&main_gpio0 {
bootph-all;
};
&main_gpio1 {
bootph-all;
};I have modified our custom board device-tree same as "k3-am625-sk.dts".
but getting below error,
