我使用的板卡是RadxaCubieA7Z，u-boot工程编译出来的输出路径有如下文件：
boot0_sdcard.bin boot0_spinor.bin boot0_ufs.bin boot_package.fex setup.ps1 setup.sh sys_partition_nor.bin

通过setup.sh脚本，把文件下载到SD卡，然后通过sd模式启动是没有问题的，可以证明工程编译是正常的。

现在我想通过USB接口，加载uboot去运行：
在ubuntu22.04上，通过apt-get install sunxi-tools，执行sudo sunxi-fel -v，报错Warning: no 'soc_sram_info' data for your SoC (id=1903)

看到有人说sunxi-tools不支持A733，然后从github下载xfel工具，sudo xfel version命令输出：AWUSBFEX ID=0x00190300(A733) dflag=0x44 dlength=0x08 scratchpad=0x000ee80，说明工具可以用了。

但是执行sudo xfel ddr命令报错：Failed to initial ddr controller。sudo xfel ddr lpddr4也是报错。

请教大家，是我命令执行错误了还是什么问题啊。

我的sys_config.fex文件关于DRAM配置如下。 我的目的是验证通过GPIO选择DRAM参数的功能，四个GPIO口悬空，上拉，应该会选择第15组参数，启动日志为：
[207]HELLO! BOOT0 is starting!
[210]BOOT0 commit : {1d640659}
[214]board gpio withstand voltage auto mode
[225]dram para15 invalid use default para

[233]fdt returned -9
[mmc]: mmc driver ver 2025-10-16 17:10
[mmc]: Wrong media type 0x0
[mmc]: Try SD card 0
[mmc]: HSSDR52/SDR25 4 bit
[mmc]: 50000000 Hz
[mmc]: 15080 MB

看起来是GPIO识别对了，按时没找到第15组参数。是配置文件哪里写的不对吗
