How to create a binary app to load and run out of RAM

Duy-Ky Nguyen88210

Hello,

So far, I'm using Boot Loader and compile an app to get OUT file, then use TI tool RPRC to generate binary image to be stored in flash at 0x10000

Now my app can load an image from PC to target via USB at high speed.

I'm thinking to use my app above as App Loader

So, I'm looking for info to load an app to load and run out of RAM. In doing so, I expect

1) A linker file to specify starting address, say 0xC2000000 in DDR

2) A make file to generate a binary to load at above address

Thanks,

See section 7.5 of the assembly language user's guide. It covers how to do this:

One you have created your linker command file correctly, then the application will be configured to load and run from that address.

Thanks

Could you specify if you have written your own bootloader code or are you refering to the bootloader code from Starterware or any other software package from TI? When you mention TI RPRC tool are you refering to the out2rprc utility ? Are you looking for a secondary bootloader to load your app or just a linker command file and build file?

Regards,

Rahul
