Hi!

Why some projects doesn't boot from internal spi flash, but correctly work when loaded from UART?

 

#include <cdefBF51x_base.h>

main()
{
    *pPORTGIO_DIR |= PG12;
    *pPORTGIO_SET = PG12;
    while(1)
    {
        *pPORTGIO_TOGGLE = PG12;
    }
}

For example:  this simple program doesn't boot on EZ-BOARD.

 

With external spi flash there is same result - doesn't boot .

 

 

Regards,

Leonid.
