Unfortunately, only 4 cores boot up. The other ones fail to boot. [12.179453] CPU6: failed to come online [13.189479] CPU7: failed to come online [14.199479] CPU4: failed to come online [15.209743] CPU5: failed to come online What should I do to enable those 8 cores ? Is there a patchset somewher= e=20 to do so ? Thanks -- Daniel --=20 Linaro.org =E2=94=82 Open source software fo= r ARM SoCs =46ollow Linaro: Facebook | Twitter | Blog
