Re: [ECOS] redboot on STM3240G-EVAL board

Thank you very much, Sergei!

the way you described works just fine:

   RedBoot> load -m x
   RedBoot> fis create app
   RedBoot> fis load app
   RedBoot> go

the app gets executed correctly! Huray!

ELF files are quite large, what is the preferred format for an image to 
be passed to redboot?
what "load" and "fis create" command look like?
