我用的usb口供电,pa0,pa1拉低后,串口可看到:
NUC970 IBR 20151008.1735
No Key
Boot from USB
但是就是不能下载程序,需要反复上电很多次才可以。
错误提示:
$install/bin/nuwriter -m nand -d NUC972DF62Y.ini -t data -a 0x200000 -w $IMAGE_PATH/image/images/uImage
init_xusb:Burn DDR to Device failed,bResult=-1
initail xusb failed -1
Failed
或者:
$install/bin/nuwriter -m nand -d NUC972DF62Y.ini -t data -a 0x200000 -w $IMAGE_PATH/image/images/uImage
device not found: Resource temporarily unavailable
initail xusb failed -1
Failed
段错误 (核心已转储)
运行成功一般会有这么提示,但成功率太低:
NUC970 IBR 20151008.1735
No Key
Boot from USB
