Hi motal,
> What boot loader is the best (and most easy) to run program regullary from flash (EPCS).
This type of question can end up in a holy war ;-)
u-boot has support for read, write, program, verify of EPCS devices (and parallel flash as well).
Is it the 'best'? -- that's pretty subjective -- depends on how you define 'best' -- only you can
answer this question. 'most easy' -- that depends on who's using it ;-)
> And field upgrading once in a while?
u-boot probably has everything you need for field upgrades: TFTP, NFS, x/y/z modem, kermit,
flash (EPCS, parallel), console, scripting, boots linux, ecos, lynxOs, etc,, etc, You should
probably take a look a redboot as well. From an open source point-of-view, u-boot appears
much more active.
Hope this is helpful.
