To ARM, if not defined CONFIG_SYS_DCACHE_OFF, dcache_enable->cache_enable(CR_C)->mmu_setup will enable mmu and build section mapping. U can try #define CONFIG_SYS_DCACHE_OFF if it is an ARM SoC board. mmu related code locates at arch/arm/lib/cache-cp15.c Regards, Peng. > > Best regards, > Stefano Babic > _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
