通过GPIO配置选择DRAM参数

gameover123 LV 2

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
[229]vaild para:15 select dram para0**
[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
