Linker script help in vxWorks - 6.6
supreet
We are building the ROM resident vxworks 6.6 image to run the vxWorks
image from flash.
In this case, the text section will be in Flash and data section will
be in SD-RAM.
i.e The text section of an object file (eg:test.o) will be in Flash
and data section in SD-RAM.
Now i want to create an addtional file (sample.c) and copy the text
sections of only this object files(sample.o) in the SD-RAM.
Please Find my linker script Below.
Let me know how can i do that in linker script????
Please reply as soon as possible.
