I'm still seeing quite some stats differences for e.g.: build/ARM/tests/opt/quick/fs/10.linux-boot/arm/linux/realview-simple-timing I am not sure why and I'd like to understand before pushing this out. The regressions all use the DDR3 config with a 64 byte burst size, so I do not see why the behaviuor should change. Amin, any ideas? - Andreas Hansson On July 26, 2013, 7:18 a.m., Amin Farmahini wrote: > > ----------------------------------------------------------- > This is an automatically generated e-mail.
