Using u-boot-2017.05 on i.MX6UL we ran into following problem: Initially U-Boot could be started normally. If we added one random command in configuration, the newly generated image hung at startup (last output was DRAM: 256 MiB). We tracked this down to a data abort within relocation (relocated_code). relocated_code in arch/arm/lib/relocate.S copies 8 bytes per loop iteration until the source pointer is equal to __image_copy_end. In a good case __image_copy_end was aligned to 8 bytes, so the loop stopped as suggested, but in an errornous case __image_copy_end was not aligned to 8 bytes, so the loop ran out of bounds and caused a data abort exception. This patches solves the issue by aligning __image_copy_end to 8 byte using the linker script related to arm. I don't know if it's the correct way to solve this, so some review would be very appreciated. |
