界面报错如下:

ERROR: Flash Operation Failed
If that FSBL fails (example hangs in DDR Init) the your u-boot under the hood won't work (Problem in running uboot).
In the FSBL you pass to the Programmer, enable all the UART log and see if it fails.
If the error is "Problem in running uboot", I suspect the FSBL specified to the flash programmer is NOT executing properly.
Best way to debug this is to enable all the FSBL prints log and check the UART print out during flash programmer.
Does the FSBL handoff properly or the prints are incomplete?
Please report the UART log in this post so I can take a look.
Project Explorer
展开 fsbl - src,打开 fsbl_debug.h,添加调试宏
#define FSBL_DEBUG_INFO
可以看到是DDR初始化失败了。
DDR勾选 internal vref
