We have surprisingly problem with projects designated for load to RAM. It includes our projects as well as examples come with Atmel cortex-m3 software package. Flash project are loaded correctly as I’ve chose proper loader in Option->Debug (J-LINK) ->Settings -> Flash Download. But what to do with SRAM? How to define loader for SRAM range…and do we have to do something like that?

Nice shot. Thank you, it was exactly the reason. Unchecked it debug sram project as i expected.
