Hi all,

 

I am using customized board based on imx6d NAND flash.

I tried to test bootdelay time as the follow.

 

#define CONFIG_BOOTDELAY 0 //_LIC : 20150224 : 3 -> 0

The result, I cannot stop u-boot to download binary image by mtd-tool.

 

1) How can I download binary image by mtd-tool ?

2) I can use JTAG(codeviser), if it is impossible to use mtd-tool,  How can I erase NAND flash memory or download binary image ?

 

Thanks and best regard.

Inchul Lee.
