From 358aec77756d6bf850a533272f2685a45220dc0c Mon Sep 17 00:00:00 2001 From: Sungbo Eo Date: Sun, 12 Jan 2020 21:36:23 +0900 Subject: ath79: add support for Arduino Yun Arduino Yun is a microcontroller development board, based on Atmel ATmega32u4 and Atheros AR9331. Specifications: - MCU: ATmega32U4 - SoC: AR9331 - RAM: DDR2 64MB - Flash: SPI NOR 16MB - WiFi: - 2.4GHz: SoC internal - Ethernet: 1x 10/100Mbps - USB: 1x 2.0 - MicroSD: 1x SDHC Notes: - Stock firmware is based on OpenWrt AA. - The SoC UART can be accessed only through the MCU. YunSerialTerminal is recommended for access to serial console. - Stock firmware uses non-standard 250000 baudrate by default. - The MCU can be reprogrammed from the SoC with avrdude linuxgpio. Installation: 1. Update U-Boot environment variables to adapt to new partition scheme. > setenv bootcmd "run addboard; run addtty; run addparts; run addrootfs; bootm 0x9f050000 || bootm 0x9fea0000" > setenv mtdparts "spi0.0:256k(u-boot)ro,64k(u-boot-env),15936k(firmware),64k(nvram),64k(art)ro" > saveenv 2. Boot into stock firmware normally and perform sysupgrade with sysupgrade image. # sysupgrade -n -F /tmp/sysupgrade.bin Signed-off-by: Sungbo Eo --- target/linux/ath79/image/generic.mk | 11 +++++++++++ 1 file changed, 11 insertions(+) (limited to 'target/linux/ath79/image') diff --git a/target/linux/ath79/image/generic.mk b/target/linux/ath79/image/generic.mk index 14e72140dc..46a8705b85 100644 --- a/target/linux/ath79/image/generic.mk +++ b/target/linux/ath79/image/generic.mk @@ -210,6 +210,17 @@ define Device/alfa-network_ap121f endef TARGET_DEVICES += alfa-network_ap121f +define Device/arduino_yun + SOC := ar9331 + DEVICE_VENDOR := Arduino + DEVICE_MODEL := Yun + DEVICE_PACKAGES := kmod-usb2 kmod-usb-chipidea2 kmod-usb-ledtrig-usbport \ + kmod-usb-storage block-mount -swconfig + IMAGE_SIZE := 15936k + SUPPORTED_DEVICES += arduino-yun +endef +TARGET_DEVICES += arduino_yun + define Device/aruba_ap-105 SOC := ar7161 DEVICE_VENDOR := Aruba -- cgit v1.2.3
