    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.
