For testing I load the Redboot ROMRAM image at 0x20300000, where it is relocated to 0x20000000. Without mmu everything works fine. When I enable the mmu after following initialization: ttb_base =3D 0x20400000 X_ARM_MMU_SECTION(0x200, 0x200, 4, ARM_UNCACHEABLE,=20=20 ARM_UNBUFFERABLE, ARM_ACCESS_PERM_RW_RW); (macro from the AAED2000 board) I get the problem that my code hangs at the end of the PLATFORM_SETUP1 macro. So there must be a mistake in the mmu init.... hardware: AT91RM9200 - ARM920T core 0x20000000 - 0x21FFFFFF (RAM) I hope there somebody out here who can help me with this problem.
