Yeah, 1.5M or 1500000 is the correct speed. My USB to serial console cables (ch341 based) work fine, but do seem a bit more temperamental with the rockpro64 output, so it looks like it might be pushing some slightly off-spec output at times when booting.
Also, with regards to the partition layout, that sounds correct. When booting directly from the SD card, the card needs to be laid out in format in order for it to be able to find what it needs to start booting.
