RE: [ECOS] kinetis kwikstik's ecos trouble

[tangwei <tziang@hotmail.com>]

Dear ilijak
for your advise:
> 1. With Redboot you should load the elf file rather bin
If I use the redboot ROM startup for kwikstik, after redboot startup can I download the example app,such as hello.elf into the kwikstik's RAM,
and then use the redboot's go command to execute the app? 
If above can work,can you give me the correct command,thanks a lot.
