In order to be able to leave data for firmware signalling the intention with a reset or to leave data for the next app in a chain of apps, we introduce a part of FW_RAM that can be used to store this data. In order to do this, we: - Change size of ROM from 6 KB to 8 KB. - Change size of FW_RAM, from 2 KB to 4 KB. - Add RESETINFO memory partition inside FW_RAM. - Add generation of map file. - Change CFLAGS from using -O2 to using -Os. - Update address ranges for valid access to ROM and FW_RAM. - Move stack to be located before data+bss and the RESETINFO data above them. This also means we introduce hardware stack overflow protection through the Security Monitor. - Revise firmware README to the new use of FW_RAM. |
