Because many configuration are expected, so avoiding many u-boot binaries is the target. Generally it seems that I want to do something that is against u-boot design, so my question should be, how to do it harmless? I changed linker script, cleared bss and it seem that this is working fine, so probably I'll try this way. > > Best regards, > > Wolfgang Denk > > -- > DENX Software Engineering GmbH, Managing Director: Wolfgang Denk > HRB 165235 Munich, Office: Kirchenstr.5, D-82194 Groebenzell, Germany > Phone: (+49)-8142-66989-10 Fax: (+49)-8142-66989-80 Email: w...@denx.de > Until you walk a mile in another man's moccasins, you can't imagine > the smell.
