Android Devkit v2.3 GB for DM37xx

Gunter,

Is this the first time you boot the board with these binaries? If it is the first time there will be some sluggishness until the system loads all the services, after the first boot you should not see the sluggishness. Just in case you can download the latest binaries from http://software-dl.ti.com/dsps/dsps_public_sw/sdo_tii/TI_Android_DevKit/TI_Android_GingerBread_2_3_DevKit_1_0/index_FDS.html and create the sd card again.

Alejandro,

thanks. I will do some more testing tomorrow. Are you saying that the Devkit binaries have a u-boot that has the SGX slow clock fixed?

Thanks,

--Gunter

No, I believe the clock was not corrected in this release, but there should be no much sluggish even though with the low clock.

Hi,

can I ask again whether there is a patch to u-boot that corrects the SGX clock to the higher speed for the 2.3 GB devkit?

Thanks,

--Gunter

Hi Gunter,

You can verify SGX clock speed with the help of following steps.

1. mount  -t  debugfs debugfs /sys/kernel/debug
2. cd /sys/kernel/debug
3. cat virt_26m_ck/osc_sys_ck/sys_ck/dpll3_ck/dpll3_m2_ck/core_ck/sgx_fck/rate

If speed is 200MHz this SGX clock is fine.

Thanks and Regards,

Pankaj Bharadiya.

I found this error, but no one answered me, please check it out.

This issue is present for me on a DM3530 board using the gingerbread-dsp branch. SGX 1.7 is built and installed, but the UI performance is terrible. In fact the UI without SGX is much better. When I cat sgx_fck I get 110666666 which I expect. This issue is present on 2.6.32, 2.6.37, and 2.6.39 kernels, has anyone found a solution?

The Rowboat gingerbread-dsp branch does not support DM3530. Have you done any changes on top of it? Do you use the EVM or custom board?

And the gb-dsp branch only supports 2.6.32 kernel at the moment. There are some work needed to port the DSP related components to support newer kernels, for example, 2.6.37. So I assume you have done such migration work.

If the UI performance is not better than without SGX, most likely the SGX driver/lib are not in use. 

I remember Aditya in this forum has helped someone solved a similar issue. the logcat message shows the SGX is not in use and Android uses s/w openGLES rendering instead. Please search this forum to find the similar post.

I am using a custom 3530 board, however I have tried building both manifest's rowboat-gingerbread-dsp and rowboat-gingerbread. Same result.

I have ported the mainline 2.6.39 Android kernel and have it running with gingerbread currently. I am building the SGX modules against the 2.6.39 kernel without error. However, I am seeing this same issue with the 2.6.32 rowboat kernel as well.

I found this post, but the solution did not fix my problem.

Thanks for any input!

Solved:

My board has a manually updated lcd display. Turns out I needed to enable this kernel option to be built inl: CONFIG_OMAP2_DSS_FAKE_VSYNC=y

I'm up and running with the 2.6.39 kernel, Gingerbread 2.3.4 DSP branch, and now working SGX. Thanks!
