SYS Bios footprint question

Other Parts Discussed in Thread: TM4C123BH6PGE

Hi All,

I have a DK-TM4C123G development kit on which i'm creating a Sys/Bios project. I notice that the size of the generated out file is 1.58Mb. Can anyone tell me how am i able to debug this on the board even when the micro controller TM4C123BH6PGE has a flash memory of only 256 Kb. I plan to make a custom board later with the same micro controller on which i intend to run Sys/Bios. Will that be possible ?

    Rakesh,

    Sys/BIOS can be configured to generate very large or very small binaries. I suggest asking the experts at the Sys/BIOS forum for more details on footprint options.

    The size of the .out file isn't representative of the amount of memory used by the program, since the .out file contains some data such as symbol addresses which doesn't get loaded to the target device. Whereas the CCS "Memory Allocation" views shows the actual memory usage on the target.

    e.g. I compiled a "hello" SYS/BIOS example for a TMC123GH6PM and the resulting .out file was 1,637,692 bytes. The CCS Memory Allocation shows that the memory usage on the target is 31,538 bytes of flash and 19,660 bytes of SRAM:
