Hi

I am working with stm32 using GNU ARM Eclipse plugin.

I want to modify the linker scripts to change the program start address

Can anyone help me?

Thanks

Can you explain more how and where i can do this ?

You could replicate the first two vectors found in the startup_stm32fxxx.s file, placing them in their own section. Then in the linker script describe a memory section starting at 0x08000000 with a length of 8 or so bytes, and direct the small vector stub into that area.

If it's easier, you could take the first 8 bytes described in the .HEX file for address 0x08003000 and replicated them in a record that gets written to 0x08000000
