I was wondering if PGCL supports Xperia P and Xperia U, both of which use U8500?

Hi rahulgarg,

We have only validated PGCL on Snowball boards from Calao Systems running Android Gingerbread. However, the compilers should work on any U8500 system running Gingerbread and it looks Xperia is running Gingerbread. Please give the compilers a try and well do our best to help even though we don't Xperia here in house.

Best Regards,

Hello,
i tried to run PGCL on an Xperia Go. But it doesn't work. Unfortunately the Xperia go runs under android 2.3.7. May be this is the reason why PGCL don't work? So i tried to put an 2.3.3 Kernel on the Xperia, but i have no success. It's impossible because there is no Kernel for this device which i can flash. May be you can give me some hints to run GPCL an this device?

Regards

Hi Markus,

Can you please give us more details on the issues you are having? Xperia Go uses a U8500 and Android 2.3.7 is Gingerbread, both of which are supported. Granted, we haven't tested on an Xperia, but in theory it should work.

Thanks,
Mat

Hi Mat,
thanks for your answer. yes you are right the processor is an U8500 and the android version is 2.3.7 but it doesn't work. I simply describe what i
have done. First i connected the mobile to an ubutu combuter via usb. The connection was succesfull. I get a shell via adb. (adb shell)
Then i get root rights on the mobile. I downloaded the pgcl file pbcl_android_12.8.tar.gz and installed it on the ubuntu computer. I tested it with the "pgcl -V" command
and it works. Then i copied the openCL library to the mobile with the command
adb push /opt/pgi/androidarm/12.8/lib/libOpenCL.so /data/pgi/lib
There is a test program in folder /opt/pgi/androidarm/EXAMPLES/Simple1. I created the program via make. Then i tested the program with the command pgrun Simple1 Simple1_Kernel.so. Then
i get the first part of the output

yaacomouser@yaacomoprod1:~/Downloads/androidarm/EXAMPLES/Simple1$ pgrun Simple1 Simple1_Kernel.so

But then nothing happens. The application simply stops. I get no error message or something. I don't know what i have done wrong.

Could you please help me?
