Android ICS AM35x problem: No android ICS support for the SGX graphics of the AM3517EVM

Hi,

There is no plan yet to support AM35x SGX in 1.8 DDK.

Right now devices supported are: AM335x, AM37x, AM389x and AM387x

Thanks for the information.

And a follow-up - is there a plan for an Android ICS support for the AM3517EVM - maybe with the SGX AM35x drivers from the older DDK 1.7 (or even the SGX kernel drivers from the Linaro ICS code of the Panda board that also provide a CONFIG_SGX_REV121 for the SGX-530 revision 1.2.1 of the AM35x)?

Thanks

And some references:

• Power VR SGX AM35x drivers from the older DDK 1.7 -  https://gitorious.org/rowboat/hardware-ti-sgx/trees/ti_sgx_sdk-ddk_1.7
• Power VR SGX Linux kernel sources for AM35x and friends -  https://launchpad.net/ubuntu/+source/powervr-omap3

I've tried to build rowboat ICS with SGX 1.7 and build succeded. Unfortunately I got following error during the boot:

I/SurfaceFlinger(26372): SurfaceFlinger is starting
I/SurfaceFlinger(26372): SurfaceFlinger's main thread ready to run. Initializing

Hi Yegor,

SGX 1.7 DDK may not work on ics directly since 1.7 DDK binaries and shared object files are not compatible with Android 4.0.

You may have to use SGX 1.8 ddk and modify it for AM35x platform.

Had already followed Pankaj's advice - but after modifying the DDK 1.8 for the AM3517EVM - I got a kernel crash when the Android ICS was loading the SGX kernel modules that where compiled by the DDK 1.8 :-(

Though you might be able to build the kernel modules, above approach of modifying DDK1.8 for AM3517EVM won't work because the SGX binaries available in the release are build for different SGX Core rev (125).

Hi Aditya,

so what is the solution of this problem? Where and when do we get 1.8 SGX drivers for am3517?

Yegor

Hi Yoger,

         I don't think we have plans for ics on am3517 at present. Hopefully you may expect the support some time next quarter.

Aditya

Hi Aditya,

I've seen this release:

http://processors.wiki.ti.com/index.php/RN_4_06_00_01

But seems to be only 1.7 + bugfixes. Any news on 1.8 stuff for am3517?

Regards,

Yegor

Hi Yegor,

       I think that release page points to Linux Graphics SDK.

Currently  am3517 is not under the priority list, however I may

be in a position to update you about the release plans some time

next week.

Hi Aditya,

thanks for the info. I'm looking forward to hear from you.

FYI: am3517 has built-in CAN controller and this makes it really interesting for industrial applications. With Android 4.0 on-board you have a flexible and configurable platform for GUI-based applications. ICS version of rowboat provides built-in Ethernet support (configuration GUI), in addition it brings ip utility to configure CAN interfaces. I've blogged about CAN support in Android (http://libbits.wordpress.com/2012/03/27/controller-area-network-can-support-in-android/) and ICS is the version that comes very close to enabling this support. One more goody is on-screen navigation bar, that makes hardware buttons obsolete.

Without 2D acceleration the handling is not responsive and it takes ages to open a new "window" compared to Gingerbread. So please keep this in mind, if discussing the priority of SGX implementation.

Hi Yegor,

      I would like to update you that the support for ICS on am35x might be available in a couple of weeks.

Aditya

Hi Aditya,

that's a good news! Thanks.

Hi,

Does the support for ICS on am35x available now?

Thanks,
