Using Boot ROM Functions to copy Data from SPI

Dirk,

Yes, you should be able to use bootloader function in BOOT ROM. All you need to do is include boot rom symbols in your project to call these function.

Only caveat is, BOOTROM functions are available in unsecure memory and you can't access secure memory contacts from unsecure memory if device is secured.

Can you give me a hint where to find the BootRom Symbols and coressponding Headers ?

I found the sprufn6a with the BootRom Source Code, but this dosen't contain any library to link against.

Or do i have to link against the Object Files and include the Linker File definitions into my Linker File ?

Dirk,

If you have installed controlsuite, you will find them in the following path.

<controlSUITE>\libs\utilities\boot_rom\2802x

Manjo,

the controlsuit contains the 2802x_IQmath_BootROMSymbols.lib which only contains the symbols for the IQMath function but none of the bootloader functions.

Also the header file Boot.h doesn't contain the needed functions they are only defined in the spi .c source coded with the comment "private functions".

The only way I currently see is using ofd2000 to extract the function addresses from "TMS320x2802x_boot_rom_Gold_v200.out" and defining them within my source code.

This leaves the Questions if this is save to use the functions if there is no normal way to access them.

Dirk,

Please try using the library file attached...

2802xRevB_BootLoader_BootROMSymbols.lib

Manoj
