Load program in flash with offset

Bram Dobbelaar Guest 2008-01-06 20:43 #1173302

Hi Forum,

I am using  Ride GCC and the target is a STR730FV1, with 128K flash in 6
sectors. I want to use the first sector to store a table and start the
program from the next sector. Can i change the the start address in the
linker setting

Regards, Bram

You can change the start of a memory-section in the linker-script. I
don't know how the RIDE IDE handles this (maybe a linker-script is
generated in the background). But it might not work to just "move" the
memory-origin since at least the reset-vector should be at address 0 in
flash. So it might be easier to use the last sectors in flash for your
table. Or you could add an extra memory section for the vectors which is
placed at page 0 and add a section for the table to be placed at pages
1-x and place the code at page x+1.
