dm8148的nandflash启动时1st uboot无法启动,没有任何打印信息,sd卡启动和SPI启动都正常,拨码开关也正常,uboot是2010.06

TI员工,你好

请问下该问题是啥原因造成的?  尝试过uboot放在SPI,内核和文件系统放在nandflash,是可以正常运行的,但是拨码调至nandflash启动,没有任何打印,编译命令如下

-rw-r--r-- 1 root root 208364 9月 16 10:48 u-boot.min.nand
-rw-r--r-- 1 root root 67020 9月 15 15:14 u-boot.min.spi

rdk包是 ipnc_3.8
