If you don't have a serial console and only use VGA/HDMI/LCD, then it might be also the case of "Unrecognized/unsupported machine ID" (see below).

For U-Boot 2018.09-rc1 or later, set CONFIG_ARMV7_LPAE=n in.

Double-check that bootm_boot_mode is set to " sec"! (see above).

If your 3.4.x kernel refuses to boot / gets stuck right after "Starting kernel.

Depending on the (possibly outdated) instructions you followed: double-check that you're not incorrectly using u-boot.bin instead of u-boot -dtb.bin, or u-boot.img instead of u-boot -dtb.img. If you're using a recent (device model based) U-Boot, and the SPL just hangs after initializing the DRAM ( CPU: 912000000Hz, AXI/AHB/APB: 3/2/2 or something similar), chances are that your main U-Boot binary may be missing DTB information / a proper device tree. The typical message in this case is " cannot reset port N!?", where N is whichever USB port those devices were attached to.Ī possible workaround is to place an external USB 2.0 hub between your board and these USB devices. Unfortunately, this also affects many USB HID / keyboard devices which would not be detected properly by U-Boot.

Previous U-Boot versions (v2015.04 and older) have a problem supporting both USB 1.x (OHCI) and USB 2.0 (EHCI) at the same time - the latter includes the SUNXI_EHCI driver for Allwinner boards. OHCI and EHCI no longer conflict with each other (after the switch to device model). U-Boot v2015.07 and later shouldn't have problems supporting mixed USB 1.x/2.0 devices. Troubleshooting USB 1.x, USB keyboards (U-Boot < v2015.07)

Look at Manual build howto for more details.

Load mmc 0:1 0x43000000 $ above) that is generated as part of your kernel compilation. Setenv bootargs console=ttyS0,115200 root=/dev/mmcblk0p2 rootwait panic=10

create a file boot.cmd on the first partition (also check Kernel arguments for extra 'bootargs' options):.

This article provides a collection of various scenarios for booting with U-Boot.įor getting these bits loaded onto the hardware, please refer to the respective howto:įor booting from SD with mainline U-Boot, the recommended way is: a SD card), but first U-Boot needs to be configured.

The installation step will instruct how to install this on the installation media (e.g.

When the build has completed, there will be u-boot-sunxi-with-spl.bin available in your u-boot tree. (When compiling natively, omit the CROSS_COMPILE=…) Make CROSS_COMPILE=aarch64-linux-gnu- B元1=/build/sun50i_a64/debug/bl31.bin Make CROSS_COMPILE=aarch64-linux-gnu- B元1=/build/sun50i_a64/debug/bl31.bin menuconfig Make CROSS_COMPILE=arm-linux-gnueabihf- menuconfigĪrm64 make CROSS_COMPILE=aarch64-linux-gnu- B元1=/build/sun50i_a64/debug/bl31.bin _defconfig Use menuconfing to play with the settings if you feel like it and then just build it:Īrmhf make CROSS_COMPILE=arm-linux-gnueabihf- _defconfig When you have determined what just configure U-Boot with a suitable default configuration. Make CROSS_COMPILE=aarch64-linux-gnu- PLAT= DEBUG=1 bl31 (See board/sunxi/README.sunxi64 in uboot sources for more infos.)

PLAT=sun50i_a64 for example is suitable for H5 and A64 devices. In order to build U-Boot for a arm64 device you need to build Arm Trusted Firmware (ATF) as a prerequisite first. So, if your device is Cubieboard2 your build target is Cubieboard2_defconfig.
