I'm learning how to port uboot recently. I have a long-forgotten MINI2440 development board. The main control chip used in the development board is S3C2440. I checked the uboot version and found that uboot does not support the MINI2440 development board, so I used the closest smdk2410 development board file for porting. And the support for smdk2410 was deleted in uboot 2017.01, but all versions before uboot 2016.11 have it, so I used uboot 2016.03 for convenience.
The first thing is to check your own compilation tool. I use the arm-linux-gcc4.3.2 version.
Using Ubuntu 16.4, enter the UBOOT root directory and execute the command:
make smdk2410_defconfig
The following error was found:
lib/asm-offsets.c:1:0: error: bad value (armv4t) for -march= switch
/*
After checking online, it turned out that the compilation chain was not specified during config. The solution is as follows:
make ARCH=arm CROSS_COMPILE=arm-linux- smdk2410_defconfig
make ARCH=arm CROSS_COMPILE=arm-linux-
After that, you can see that the compilation is completed successfully, indicating that there is no problem compiling it using this version of the compilation tool.

Exynos4412 Uboot transplantation (IV)——Uboot kernel boot process analysis
To start the kernel, the bootloader can jump directly to the first instruction of the kernel, that is, the starting address of the kernel, so that the kernel startup can be completed. However, to start the kernel, some conditions must be met, as shown below: 1. CPU register settings * R0 = 0 * R1 = machine
