This function is completely in assembler... What makes you sure barebox stops there? Do you have DEBUG_LL enabled or do you use a JTAG debugger? Does this happen in first stage boot only or also when you chainload barebox from an already running barebox? You could try calling imx53_init_lowlevel_early from barebox_arm_reset_vector(). This *could* make a difference. Since you are using v2013.05-stable you should have the following patches, but maybe it's worth rechecking. 76820df ARM: invalidate data caches during early init f9d7582 ARM v7: added v7_mmu_cache_invalidate() ee5f859 ARM v7: v7_mmu_cache_flush(): do not restore r0-r3 (minor optimization) eb7d85c arm: properly init alignment trap bit 7904d90 ARM v7: fix mmu-off operation 9af1150 ARM: fix the memset fix Sascha -- Pengutronix e.K. | | Industrial Linux Solutions | http://www.pengutronix.de/ | Peiner Str. 6-8, 31137 Hildesheim, Germany | Phone: +49-5121-206917-0 | Amtsgericht Hildesheim, HRA 2686 | Fax: +49-5121-206917-5555 | _______________________________________________ barebox mailing list barebox@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/barebox
