2. The "Incompatible HW and SW" message suggests that the "current"
android image was built before the STORM series with the DM37x cores (which
evidently carry a later-rev SGX core). Is there a more current gumstix Android
effort underway? Do drivers exist for the latest SGX core? If not, how can I
coax the available pre-built image to boot on the WaterSTORM COM?
not sure if the people that created gumdroid are continuing to work on
the DM37x you need a later rev of the SGX core drivers. The omap3530 uses
version 3.x and the DM37x uses 5.x. I have got my custom built Android to work
with the WaterStorm, but I had to mod the Makefiles so it built the driver with
version 5.x instead of 3.x.
don't use the pre-built image so I can't help you in coaxing it into working,
other than to say you would need the 5.x version of the sgx drivers and copy
them into the image and delete the others? Assuming that would
the kernel that is used with the gumdroid doesn't (or didn't for me) support the
DM37x mcu, I had to patch the kernel so it would detect the cpu correctly and
use the right OPP tables so I could run it at 800MHz. This can't be fixed on the
pre-built image less you patch and built your own kernel or they have fixed it.
