Is it possible to control upp from arm?

Hi,

I plan to develop a Linux driver for upp instead of using BIOS upp driver. Is it doable?

The first problem that confuses me is would arm be notified by the upp interrupts?

Hi Charles,

Please check sprs586f.pdf -omap-l138 datasheet you can see on the AINTC System Interrupt Assignments table that interrupt 91 is the uPP_ALLINT - uPP Combined Interrupt

Thanks,

Hi,

Yes, It is possible. The basic upp example will be at: BSL_test_code_LogicPd_OMAP-L138\ARM EVM UPP Test.
Go to LogicPD's web site, Click on the Kit Contents tab, at the bottom of the page click at:
OMAP-L138 SOM-M1 GEL, CCS Setup, & BSL Files - you will need to create an account in their website if you do not have one already and download the files.
And alos find the latest Linux SW release, for OMAPL138 MCSDK (mcsdk_1_01_00_02_setuplinux.bin)

I think so, there is no upp driver code for OMAP-L138 at the linux PSP
