What to do if the Linux compilation error 404 is displayed on the RK3568 development board? Tactile Intelligence will teach you how to solve it easily! [Copy link]

This article introduces the compilation process of Rockchip RK3568 motherboard/development board SDK and the solution to compilation errors. It uses the Touch Intelligence EVB3568 Hongmeng development board for demonstration, which has rich video input and output interfaces (HDMI/eDP/MIPI/LVDS) and multiple high-speed interfaces (Gigabit Ethernet/PCIe/SATA/CAN, etc.). In the near future, Touch Intelligence will release the RK3568 series open source Hongmeng OpenHarmony5.0 system firmware, so stay tuned!

SDK compilation process

• Select the development board configuration

ronnie@dell-PowerEdge-R430:~/work/evb3568v1_linux_sdk$ ./build.sh lunch

processing option: lunch

You're building on Linux

Lunch menu...pick a combo

0. default BoardConfig.mk

1. BoardConfig-rk3568-ido-evb3568-hdmi-dlvds.mk

2. BoardConfig-rk3568-ido-evb3568-hdmi-edp.mk

3. BoardConfig-rk3568-ido-evb3568-hdmi-mipi0.mk

4. BoardConfig-rk3568-ido-evb3568-hdmi-mipi1.mk

5. BoardConfig-rk3568-ido-evb3568-hdmi-slvds.mk

6. BoardConfig-rk3568-ido-evb3568-hdmi.mk

Which would you like? [0]:

By default, the SDK configures the corresponding mk according to the screen of the development board. For example, if you want to compile the firmware of HDMI+single LVDS, select the firmware BoardConfig-rk3568-ido-evb3568-hdmi-slvds.mk.

• File system selection

File system through the environment variable RK_ROOTFS_SYSTEM

System choice: Buildroot/Debian/Ubuntu

For example, if you choose Debian, you need to assign the value Debian to RK_ROOTFS_SYSTEM:

export RK_ROOTFS_SYSTEM=debian

• Start Compiling

The command is as follows:

export RK_ROOTFS_SYSTEM=debian

If lunch has switched to mk before, the compilation will pop up the IO Domain Checklist pop-up window:

Note that vccio4 and vccio6 are set to 1.8V, and the others are set to 3.3v. In the pop-up window, use the up and down keys on the keyboard to select the correct value.

After the compilation is complete, the image will be generated in the rockdev directory:

~/work/evb3568v1_linux_sdk$ ls rockdev/

boot.img MiniLoaderAll.bin misc.img oem.img parameter.txt recovery.img rootfs.ext4 rootfs.img uboot.img update.img userdata.img

tfs.ext4 rootfs.img uboot.img update.img userdata.img

Among them, update.img is the complete firmware package.

Solution to ERROR404 error when compiling SDK

As shown in the following figure:

Cause: This problem occurs because the compilation needs to download related files from the external network, but the compilation fails because the network speed is too slow.

Solution: Copy and unzip dl.zip to the corresponding path and replace the original dl directory. The path is:

evb3568v1_linux_sdk/buildroot/dl
