It is based on Texas Instruments AM6232 or AM6254 SoC. Its dual or quad A53 cores can provide higher performance than classic PocketBeagle. The new design comes with pre-soldered headers, a 3-pin JST-SH 1.00mm UART debug port, a USB-C port, Texas Instruments MSPM0L1105 Cortex-M0+ MCU for ADC, 512MB RAM, and a LiPo Battery charger. https://www.beagleboard.org/boards/pocketbeagle-2 https://openbeagle.org/pocketbeagle/pocketbeagle-2 Signed-off-by: Robert Nelson CC: Rob Herring CC: Krzysztof Kozlowski CC: Conor Dooley CC: Vignesh Raghavendra CC: Nishanth Menon CC: Andrew Davis CC: Roger Quadros CC: Siddharth Vadapalli CC: Judith Mendez CC: Andrei Aldea CC: Dhruva Gole CC: Jason Kridner CC: Deepak Khatri CC: Ayush Singh Reviewed-by: Dhruva Gole --- Changes since v1: - fix '_' in main-i2c2-default-pins - aliases i2c match original pocketbeagle - add mcu_m4fss with reseved memory and mailbox - drop unused main_gpio0_pins_default pinmux - drop unused main_gpio1_pins_default pinmux - drop unused main_spi2_pins_gpio pinmux - Reserve 128MiB of global CMA --- arch/arm64/boot/dts/ti/Makefile | 1 + .../boot/dts/ti/k3-am62-pocketbeagle2.dts | 528 ++++++++++++++++++ 2 files changed, 529 insertions(+) create mode 100644 arch/arm64/boot/dts/ti/k3-am62-pocketbeagle2.dts diff --git a/arch/arm64/boot/dts/ti/Makefile b/arch/arm64/boot/dts/ti/Makefile index 03d4cecfc001..4f8fcb69a2c1 100644 --- a/arch/arm64/boot/dts/ti/Makefile +++ b/arch/arm64/boot/dts/ti/Makefile @@ -27,6 +27,7 @@ dtb-$(CONFIG_ARCH_K3) += k3-am625-verdin-wifi-yavia.dtb dtb-$(CONFIG_ARCH_K3) += k3-am62x-phyboard-lyra-gpio-fan.dtbo dtb-$(CONFIG_ARCH_K3) += k3-am62-lp-sk.dtb dtb-$(CONFIG_ARCH_K3) += k3-am62-lp-sk-nand.dtbo +dtb-$(CONFIG_ARCH_K3) += k3-am62-pocketbeagle2.dtb # Boards with AM62Ax SoC dtb-$(CONFIG_ARCH_K3) += k3-am62a7-sk.dtb diff --git a/arch/arm64/boot/dts/ti/k3-am62-pocketbeagle2.dts b/arch/arm64/boot/dts/ti/k3-am62-pocketbeagle2.dts new file mode 100644 index 000000000000..65000ed8196f --- /dev/null +++ b/arch/arm64/boot/dts/ti/k3-am62-pocketbeagle2.dts @@ -0,0 +1,528 @@ +// SPDX-License-Identifier: GPL-2.0-only OR MIT +/* + * https://www.beagleboard.org/boards/pocketbeagle-2 + * + * Copyright (C) 2025 Texas Instruments Incorporated - https://www.ti.com/ + * Copyright (C) 2025 Robert Nelson, BeagleBoard.org Foundation + */ + +/dts-v1/;
