Dear Wolfgang Denk, Thanks for your response, I also answer your question below.
Are "Standalone Applications" supported in the current u-boot (GIT
repo)?
Standalone Applications are no operating systems,m so "bootm" is the
wrong command.
This is the answer I was expecting, bootm does not support Standalone Application Images. My question was not complete, I thought it was not necessary to repeat the mail subject. It should have been: "Are Standalone Application Images supported by bootm in the current u-boot (GIT repo)?"
That's because Standalone Applications don't use image files and bootm. They use the "go" command as documented in the manual.
Is this so difficult?
Probably not so difficult, however "go" on its own does not complete the job I want to do. I want u-boot to start a Standalone Application that is stored in flash without user interaction. In order to do that I have to copy the Standalone Application from flash to ram (it is not XIP) and then run it from ram. I will try to use scripting.
In any case it was easier with u-boot 1.2.0 where the bootm command did support Standalone Application Images making the program copy and run all in one go.
Best regards,
Rodrigo Vilar
