return() from a u-boot application

Hi,

We have a u-boot "application" (based on hello_world example) which implements system specific boot control functions. Normally, a return() call from main() will return control back to the u-boot command line. We have several error handling subroutines which report and log errors through a proprietary PCI based interface.

Would anyone know how to directly return back to the u-boot command line from within a subroutine which was called from main()? Maybe something like an exit() call. I want to avoid having to return error codes from multiple level of function calls back to main - even though it might not be good coding style.

I did try an exit() call but it was undefined. If I export it from U-Boot, will it work? i.e return control back to u-boot.

Thanks for any suggestions.

There is no way to do this rigth now.

No, it will not work.

You probably want to implement something like setjmp() and longjmp().

Thank you for the setjmp/longjmp suggestion. That should do the job.
