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

gal Shalif

Other Parts Discussed in Thread: AM3517

Problem description

Android ICS can not be build for the AM3517EVM board because there is no SGX graphics for the AM35x with the ti_sgx_sdk-ddk_1.8

Note: The rowboat ICS sources (see reference below) for the AM37x (i.e. BeagleBoard xM) are used as a base for my modifications for the AM3517EVM

Question

When will be an ICS support (i.e. DDK 1.8 or later) for the SGX-530 graphics of the AM35x?

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

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
graphics H/W...
E/FramebufferNativeWindow(

26372): couldn't open framebuffer HAL (No such device)E/SurfaceFlinger(26372): Display subsystem failed to initialize. check logs. exiting...

Any idea what's wrong and where to look?

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?

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.

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?

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.

Aditya

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.

Yegor
