Jelly Bean 4AJ.2.3 Ducati firmware

Steve Schefter

Hi.

Previous releases of JB for OMAP4 had the firmware name ducati-m3.bin built into the kernel file arch/arm/mach-omap2/remoteproc.c. Also, the file ducati-m3.bin was included in the tarball device/ti/proprietary-open/omap4/ducati_blaze_tablet.tgz.

Now in the 4AJ.2.3 release, arch/arm/mach-omap2/remoteproc.c specifies the firmware name ducati-m3-core0.xem3. But the ducati tarball still contains ducati-m3.bin, not ducati-m3-core0.xem3.

I tried renaming the firmware, but the format is not what is expected by the core remoteproc driver. drivers/remoteproc/remoteproc_core.c generates the error "rproc remoteproc0: Unsupported class: 2". That's because ducati-m3.bin is ELF class 64 while remoteproc expects ELF class 32.

Where can I obtain ducati-m3-core0.xem3 suitable for 4AJ.2.3?

Regards,

Steve

This is true for the 2.4 release also. I don't understand how these can be released without pushing the correct firmware, none of the devices will work correctly????

You can download this file from

Thanks Frank. I'll give the binary at the first link a try.

Unfortunately, the second link is the one indicated in the TI OMAP4 JB wiki and it contains only older, incompatible Ducati binaries. It only goes as far as 4AJ.2.2 and has ducat-m3.bin rather than ducati-m3-core0.xem3.

Hi Steve,

please scroll down to the "Android on Blaze Tablet" section of the pre-built binaries page.

There you find the required file.

Best regards

Thanks Frank. I hadn't noticed that Blaze Tablet was more up-to-date than Blaze.

For what it is worth, since reporting this problem I've been in touch with the 4AJ PM. He indicates that a patch will soon be submitted to the device/ti/proprietary-open project to update the tarballs with the correct Ducati firmware. For anyone else running into this, I'll report back here when I see that submitted.

Regards,

Steve
