Tool/software:
Hello TI ,
I am currently working with AM625-Q1 custom board and using U-Boot 2025.01 (default k3-am625-sk.dts) as provided in the Processor SDK 11.00.09.04.
I noticed that in this version, the DTS files are located under:
Whereas in U-Boot 2024.04 and earlier versions, the DTS files were located under:
arch/arm/dts
My questions are:
-
Why are the DTS files now placed under the
upstreamfolder in 2025.01? Does this indicate that it is still under development? -
I currently have a working DTS from U-Boot 2023.04 (path:
arch/arm/dts). I have attached my working 2023.04 DTS (k3-am625-sk.dts) below.-
How to port my custom DTS changes from 2023.04 to 2025.01 ?
(For example, As a standard procedure for custom board, should I directly copy my custom old DTS into arch/arm/dts with custom board name dts ? and how to make sure this newly added dts will override the default k3-am625-sk.dts andwhat are the recommended steps to port properly?) // SPDX-License-Identifier: GPL-2.0 /* * AM625 SK: https://www.ti.com/lit/zip/sprr448 * * Copyright (C) 2021-2022 Texas Instruments Incorporated - https://www.ti.com/ */ /dts-v1/; #include <dt-bindings/leds/common.h> #include <dt-bindings/gpio/gpio.h> #include <dt-bindings/net/ti-dp83867.h> #include "k3-am625.dtsi" / { compatible = "ti,am625-sk", "ti,am625"; model = "Texas Instruments AM625 SK"; aliases { serial2 = &main_uart0; mmc0 = &sdhci0; mmc1 = &sdhci1; mmc2 = &sdhci2; spi0 = &ospi0; ethernet0 = &cpsw_port1; ethernet1 = &cpsw_port2; usb0 = &usb0; usb1 = &usb1; }; chosen { stdout-path = "serial2:115200n8"; bootargs = "console=ttyS2,115200n8 earlycon=ns16550a,mmio32,0x02800000"; }; opp-table { /* Add 1.4GHz OPP for am625-sk board.
