Enhancement request -- Version string area in _c_int00

Raymond Mack

Hey y'all:

Yet another request to add something when you can. It is a pretty normal task to need to store a version string in an executable binary. Guessing most folks find a need for this feature. It is always nice to have a fixed address so one can easily find it using development system tools as well as at run time. Hard to tell whether this belongs here or in the compiler or RTOS forums. Seems to me there are a couple of things to do:

1) Carve out a user specified size array of characters right after the vectors (in ARM) to hold the version string.

2) add an item to the XDC RTOS configuration so that the xdc system will hold the version string in the config script and set up xdc to put that string right after the vectors.

Asking for this enhancement since boot.asm does not appear to be set up to be user modified.

Thanks for considering.

I presume you build with the newer EABI, and not the older TI_ARM9_ABI. In that case, this will work ...

#define VERSION_ADDRESS 0x1000
#pragma LOCATION(version_string, VERSION_ADDRESS)
#pragma RETAIN(version_string)
char version_string[] = "version info here";

Thanks and regards,

George:

This is way cool!!! We are using whatever is new, so yes, we should be using the new EABI.

Thanks for the information. It will really help us with an easily located version string!!
