I noticed most bare-metal examples included with DS-5 that rely on a FVP also include startup code (e.g. startup.s). However, there's one bare-metal example (Calendar program for Cortex-A8-FVP) that only includes code for the main program. How is model startup handled in this case? Can all FVP models be run in this manner or is it something specific to the Cortex-A8-FVP?
In the debug configuration settings I don't see any noticeable differences between the examples outside of a different FVP model being used. I was half expecting some sort of "use default startup sequence" check-box, but didn't find it.
Thanks for any help!
Yes, that's right. The scatter file tells the linker how/where the code/data should be placed in the memory map by __scatterload. The simple calendar example has no scatter file so a default layout is used. The default layout is program code (.text) first starting at --ro-base, followed by RW data (.data), followed by ZI data (.bss). The armlink User Guide gives more information - see section 3.6.
