AM625: The mirror cannot be started after the u-boot and defconfig are modified

toby Tang

Part Number: AM625

SDK8.6

I want to create the directory and configuration file that matches my own board in uboot. However, an error occurs if spl/u-boot-spl.bin exceeds file size limit after I modify uboot and compile using yocto. After I changed the SPL_SIZE_LIMIT to 0X3B7F0, it would compile but not start successfully.

At present, the modified u-boot can compile successfully but boot without any print. After replacing the unmodified tiboot3.bin and tispl.bin, it can start successfully

What should I pay attention to if I want to modify defconfig and successfully compile the startup image using yocto

At present, the modified u-boot can compile successfully but boot without any print. After replacing the unmodified tiboot3.bin and tispl.bin, it can start successfully

The following image shows an error in the tispl.bin file

Hi Toby,

Are you using Processor SDK ?

是的，我正在使用 SDK8.6，并且我正在为 SDK 8.6 自己的主板添加 uboot 目录和配置

Hi Toby,

Can you reply in English?

Also, you should be careful when modifying the size of SPL. During R5 stage we are using SRAM which is limited in space.

I was about to modify the uboot to add the directory and configuration of my motherboard, but when I modified the image compiled by yocto could not start without printing

Hi Toby,

You may have removed the compile time error for SPL size, but now have a boot time error. What is happening is that your stack may have grown beyond to the SPL region and corrupted your SPL. I recommend removing from R5 SPL what you do not need. Do not change size of SPL, allow during compile to tell you if your SPL is too large. Here is an image of SRAM during r5 stage for your reference:
