Hi
I have a problem with flash programing, I have my F2812 custom board and run my program in internal ram then it's work good. i use xds510 emulator,
now i want to load my code into flash for stand alone working.
the problem is my code runnning but some peripheral not work in this mode,ADC_ISR and T0_ISR are work but SCI and SPI not work, i track my code and saw SCI and SPI ISR running but no data send to output,
I readed all ti document about flash programing but dont understand why.
some of my initialize code and my CMD are here,
i'm really confused,
thank you for your attention.
Amin
