MMDSP Debugger 1 1

Example for Breakpoints

Assume you have a target with FLASH from 0 to 0xFFFFF and RAM from 0x100000 to 0x11FFFF. The

command to configure TRACE32 correctly for this configuration is:

The following breakpoint combinations are possible.

Software breakpoints:

On-chip breakpoints:

Downloading Program Code to the Video Core

The STN8810A and STN8810V are not object code compatible. When loading a program that was compiled

for the wrong core, the message “file not compiled for this processor” is displayed.

The Video Core employs a compression algorithm based on a dictionary. The dictionary is dynamically

created while downloading the object code to the target. The algorithm exploits the fact that some

instructions do not use all fields of the opcode to obtain better compression. While the functionality of an

instruction is not affected by compression/decompression, a reconstructed opcode will not be necessarily

binary identical to the original opcode. Therefore the /verify option for the data.load command may

produce false error message when used for download code to the video core.

Changing the FLAG Register

Changing the FLAG register through the debugger is not supported.
