From 0784d07c11eb0eadf0d4426cc7dba3642ff5762c Mon Sep 17 00:00:00 2001 From: =?utf8?q?Petr=20=C5=A0tetiar?= Date: Mon, 16 Mar 2020 10:57:50 +0100 Subject: [PATCH] sunxi: a53: add support for Olimex A64-Olinuxino eMMC MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Specifications: SoC: Allwinner A64 (1.2 GHz Quad-Core ARM Cortex-A53 64-bit) RAM: 1GB or 2GB RAM DDR3L @ 672Mhz Flash: 0/4/16GB eMMC flash memory for storage and boot MicroSD card connector for cards up to 32GB Debug: serial UART debug header with 0.1" pins Wired connectivity: 10/100/1000Mbps GbE Ethernet Wireless connectivity: on-board RTL8723BS 1T1R 802.11bgn WiFi and Bluetooth 4.0 module with built-in antenna (only available in the A64-OLinuXino-1G4GW) Flashing instructions: Standard sunxi SD card installation procedure - copy eMMC image to SD card, insert in into SD card slot on the device and boot. You should see something like following if the eMMC is detected correctly: mmcblk2: mmc2:0001 P1XXXX 3.60 GiB mmcblk2boot0: mmc2:0001 P1XXXX partition 1 16.0 MiB mmcblk2boot1: mmc2:0001 P1XXXX partition 2 16.0 MiB Then flash SD card eMMC image straight into the mmcblk2 device: dd if=/mnt/openwrt...a64-olinuxino-emmc-squashfs-sdcard.img of=/dev/mmcblk2 It also possible to boot from boot0 partition[1]: 1. Compile U-Boot with CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR=0x40 otherwise the U-Boot will get stuck in bootloop 2. Configure eMMC to boot from boot0 partition inside U-Boot: mmc bootbus 1 1 0 0; mmc partconf 1 1 1 0 3. echo 0 > /sys/block/mmcblk2boot0/force_ro 4. Write U-Boot from offset 0 (not offset 8k as with SD card) into boot0 partition dd if=u-boot-sunxi-with-spl.bin of=/dev/mmcblk2boot0 Known issues: Wireless doesn't work properly via netifd. 1. https://linux-sunxi.org/index.php?title=Bootable_eMMC Signed-off-by: Petr Å tetiar --- target/linux/sunxi/image/cortex-a53.mk | 10 ++++++++++ 1 file changed, 10 insertions(+) diff --git a/target/linux/sunxi/image/cortex-a53.mk b/target/linux/sunxi/image/cortex-a53.mk index 96885cf926..7a70de4dff 100644 --- a/target/linux/sunxi/image/cortex-a53.mk +++ b/target/linux/sunxi/image/cortex-a53.mk @@ -47,6 +47,16 @@ define Device/olimex_a64-olinuxino endef TARGET_DEVICES += olimex_a64-olinuxino +define Device/olimex_a64-olinuxino-emmc + DEVICE_VENDOR := Olimex + DEVICE_MODEL := A64-Olinuxino + DEVICE_VARIANT := eMMC + DEVICE_PACKAGES := kmod-rtl8723bs rtl8723bs-firmware + $(Device/sun50i-a64) + SUNXI_DTS := $$(SUNXI_DTS_DIR)$$(SOC)-olinuxino-emmc +endef +TARGET_DEVICES += olimex_a64-olinuxino-emmc + define Device/pine64_pine64-plus DEVICE_VENDOR := Pine64 DEVICE_MODEL := Pine64+ -- 2.25.1
