Other Parts Discussed in Thread: ADS901, OMAPL138, OMAP-L138

I want to use analog input via ADS901 on UI Board of Logic PD's OMAP-L18 EVM on linux. I will develop a Qt application that will draw waveform of analog input. I am using Allan's Linux UPP driver. I compiled UPP driver and load it with inmod command on the EVM. It is loaded without any problem but graphical LCD is gone away. What can I do to get over this problem? Should I reconfigure kernel?

I also cannot run UPP example application. It gives me an error (19).

Thanks.

Mehmet,

I understand that you are using LogicPD OMAPL138 EVM board for UPP.
I am not sure about the Allan's Linux UPP driver will work on this board.
Please kindly refer the below wiki pages for UPP and examples.
http://processors.wiki.ti.com/index.php/Introduction_to_uPP
http://processors.wiki.ti.com/index.php/Using_the_uPP_DSP/BIOS_Driver
http://processors.wiki.ti.com/index.php/Using_the_uPP_EVM_example_applications_from_the_BIOS_PSP
And also look UPP test code from the BSL which is provided by logicPD.
As per the below path, you can get the test code for UPP
BSL_test_code_LogicPd_OMAP-L138\ARM EVM UPP Test
Look the section "33.2.6 Initialization and Operation" in the OMAPL138 TRM(spruh77)
