 Hi Madhu Sudhan

   

I have a normal code in SPI ROM,

   

Now, i read SPI ROM the n'th page date 4k byte.

   

And i erase the n'th page data than re-write new 4k byte to the n'th page.

   

When i reset, the code can not run my normal code, it is run boot code.

 Hi,

   

It is not recommeded to make such editings to the Boot Code at random nth locations. The Boot image has a format, which if edited, the mage becomes corrupt.

   

In case of a corrupt image the the boot mode will fall back from SPI to USB.
