Hi all, I'm currently working with the imx7d sabre board from NXP. I have now a running barebox bootloader and a booting kernel. My problem is now that, apparently, only one core is active: ... commandline: console=ttymxc0,115200n8 ip=11.0.0.4::11.0.0.2:255.0.0.0::eth0: root=/dev/mmcblk0p2 rootdelay=1 Starting kernel in secure mode [ 0.000000] Booting Linux on physical CPU 0x0 [ 0.000000] Linux version 4.17.7 (giorgio@BV_blfs) (gcc version 8.1.0 (OSELAS.Toolchain-2018.02.0)) #1 SMP Wed Jul 18 07:44:41 CEST 2018 [ 0.000000] CPU: ARMv7 Processor [410fc075] revision 5 (ARMv7), cr=10c5387d [ 0.000000] CPU: div instructions available: patching division code [ 0.000000] CPU: PIPT / VIPT nonaliasing data cache, VIPT aliasing instruction cache [ 0.000000] OF: fdt: Machine model: Freescale i.MX7 SabreSD Board [ 0.000000] Memory policy: Data cache writealloc [ 0.000000] cma: Reserved 64 MiB at 0xba000000 [ 0.000000] percpu: Embedded 14 pages/cpu @(ptrval) s36392 r0 d20952 u57344 [ 0.000000] Built 1 zonelists, mobility grouping on.
