Unfortunately, during the boot process, i.MX8M requires a closed-source firmware for an embedded ARCompact processor in the Synopsys DDR4 PHY. This firmware, which is only a few kilobytes in size, is responsible for regulating the physical connection to the DDR chips in the face of changing temperatures. We are in contact with reverse engineers with the goal of analyzing what the capabilities of this so called PHY Utility Block (PUB) are, and to find out if we have a chance to replace this firmware at some point in the future.
