Hi,
I’m confused when I use memcpy() in pandaboard android. The test code is very simple, as below:
#define PER_COPY_SIZE (1024*1024*4)
int main(int argc, char *argv[ ]){
char *src;
char *dst;
char *p;
src=(char *)malloc(PER_COPY_SIZE);
dst=(char*)malloc(PER_COPY_SIZE);
p=src;
#if 1
for(int i=0; i<PER_COPY_SIZE; i++){
*p++=i%255;
}
#endif
for(int j=0; j<1000; j++){
memcpy(dst, src, PER_COPY_SIZE);
}
free(src);
free(dst);
return 0;
}
It copies 4M byte data from source to dest repeatedly and takes 12 seconds. But when I get rid of the part of code in red color, it takes only 4 seconds. Why does the writing to source firstly has influence the memcpy( ) time so greatly?
Thanks & Best Regards!

Hi，
I want compile pandaboard GPU driver myself and get the library, such as “libEGL_POWERVR_SGX540_120.so”, “libIMGegl.so” and so on. How can I get the GPU driver source code and compile environment?
Thanks & Best Regards!

Hi Josep,
The graphics binaries are missing on the sdcard. Currently the graphics
installer script "install-binaries.sh" equivalent for windows is not
available . You will need a linux machine to install the binaries.

Dear Vishal,
>From the Linaro mailing list, I think you are the expert for Pandaboard ES platform issues.
So your help for this problem would be very much appreciated:
I am just getting started with Android prebuilt images on Pandaboard ES platform, but I don’t have success with any prebuilt image available on your download section.
As I’m not a Linux expert, prebuilt images are written on SD-Card with Win32 Disk Imager.
- Several prebuild images tested, but Android does not work with any of them.
- 2 diferent boards tested, but unfortunately the result is the same (even hadware validation is ok for both boards).
It has been observed the top of OMAP4460 device is getting very hot, so the board has been powered off in order to avoid any hardware damage.
Several error messages on the terminal, unable to analyze all of them one by one.
Please could you help me ?
Thanks,
Josep

Hi,
Calendar Week 42: Here is test result summary for Linaro Android
platform on following boards:
1) ARM Versatile Express A9
2) ST-Ericsson Snowball
3) TI Panda Board 4430
4) TI Panda Board 4460
5) Samsung Origen
*Synopsis - Android version for all the boards mentioned above
has changed to 4.1.2. Glmark2 and wifi/BT still not working on panda. On
other boards Vexpress-a9, Origen and Snowball no major differences are
observed compared to the last week testing. For more detail test results,
please check the last column of the spreadsheet provided above. *
*
*
1) *ARM Versatile Express A9* -
https://docs.google.com/a/linaro.org/spreadsheet/ccc?key=0AkxwyUNxNaAadExQd…
Features like glmark2,
youtube, speech recorder, email, calendar and people still dont work. Test
results are similar to last week.
2) *ST-Ericsson Snowball * -
https://docs.google.com/a/linaro.org/spreadsheet/ccc?key=0AkxwyUNxNaAadEF1N…
This week test result is
similar as week 41. WiFi,BT,youtube still not working. SD card still not
getting detected blocking few other test cases.
3)* TI Panda Board 4430 * -
https://docs.google.com/a/linaro.org/spreadsheet/ccc?key=0AkxwyUNxNaAadGVWd…
Phone app still missing on
panda. SD card is still an issue which blocks few test cases. Hardware
graphics acceleration works fine.
4) *TI Panda Board 4460 * -
https://docs.google.com/a/linaro.org/spreadsheet/ccc?key=0AkxwyUNxNaAadGVWd…
Same comment as Panda 4430.
5) *Samsung Origen * -
https://docs.google.com/a/linaro.org/spreadsheet/ccc?key=0AkxwyUNxNaAadDRDV…
All features remain the same
status as previous week, except the tool chain version has been switched to
the 12.10. Ethernet adapter can only work after a command line based
manually setting, and due to WiFi is unavailable, this is the only way we
let the board be online. Google Apps can only work on "local" mode, Device
Tree, Video playback and HDMI display are still unavailable.
Note: Calendar week 41 result attached for reference.
