Question about working_area in Openocd config file

Development Boards MicroMod

Hello all,

This is what in the Openocd cfg file:

working_area 0 0x40000000 0x40000 nobackup

I am really confused. I read the Atmel AT91SAM7 datasheet. The address 0x40000000 falls under “undefined” region. How does Openocd work with that address?

The working area line:

working_area 0 0x40000000 0x40000 nobackup

has probably been copied from a LPC config file, where it is a valid address.

For the AT91SAM7 it should be changed to a valid address, at 0x200000 .

The reason that OpenOCD still works with this config is that the AT91SAM7 flash

code does not use the working area.
