> U-boot by design starts on Core0. Other cores are not touched and are managed (started/configured) by Linux. The other question is if you use the ARM Trusted Firmware [ATF]. If you start/load it in U-Boot (or any earlier bootloader), then it also may change / configure CPUs state. > Kind regards, > > Mels > _______________________________________________ > U-Boot mailing list > U-Boot@lists.denx.de > https://lists.denx.de/listinfo/u-boot Best regards, Lukasz Majewski -- DENX Software Engineering GmbH, Managing Director: Wolfgang Denk HRB 165235 Munich, Office: Kirchenstr.5, D-82194 Groebenzell, Germany Phone: (+49)-8142-66989-59 Fax: (+49)-8142-66989-80 Email: lu...@denx.de
