This feature works fine.

Declare checksum section in linker script, eg. +seg .text -b 0xf000 -m 0x1000 -n .text +seg .const -a .text -n .const +seg .cksum -ik -a .const -n .cksum mark the section to be checked with the -ck in the script. Then call one of the checksum functions, eg. _checksum() this will return zero for program checksum ok. Further details are given in the cosmic manual. Hope this helps. sjo

just be careful for those applications that need to start up ''fast''; calculating the checksum on a big chunk of code can be a bit slow.
