[sp] No, it was not for measuring u-boot but for a small application that I wanted to compare for power consumption. It is probably easier to play with caches, MMU, etc. in the u-boot than in Linux kernel. Application is merely a calculate-wait-calculate kind of loop. ~sanjeev > > Best regards, > > Wolfgang Denk > > -- > DENX Software Engineering GmbH, MD: Wolfgang Denk & Detlev Zundel > HRB 165235 Munich, Office: Kirchenstr.5, D-82194 Groebenzell, Germany > Phone: (+49)-8142-66989-10 Fax: (+49)-8142-66989-80 Email: w...@denx.de > Just because your doctor has a name for your condition doesn't mean > he knows what it is. > > _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
