I've been testing the boostd for a few Marvell boards and seeing this error on the Thecus N2350 (Marvell Armada 385, dual-core CPU). The "bootflow scan scsi" command triggered the "CACHE: Misaligned operation at range" error. However, this error did not affect the result of the scan, i.e. the bootflow for scsi partition was created correctly, and u-boot is running normally.
Enabling CONFIG_SYS_DCACHE_OFF got rid of the errors altogether. Perhaps this is a case where the DCACHE is not required and should be turned off?
Please see the log after the break below.
All the best, Tony
