Research direction
Reproduce the latest BSP booted through TFTP, then mount the SD card and compare the failure with the supplied backtrace. Start at the listed entry points, including init_sd, mmcsd_detect, rt_mmcsd_blk_probe, mbr_device_probe, and rt_device_register; done means identifying the cause of the data abort and confirming that SD mounting no longer crashes.
