Usage of SPI bus

anu

Hi,

I am using OMAPL132 Processor where i am trying to use SPI bus connected to NOR flash both from ARM and DSP. During that time, i m not able to access from DSP.

I cant figure out the problem(But standalone DSP it is working)

Could somebody help me.

Anu,

Whats is running on the ARM? Have you ensured that the ARM application is not changing the PIN MUX settings of the device which may cause the SPI flash to be in accessible from the DSP.

Hi Rahul,

I have cross verified the PIN MUX settings it is not causing any issue. In ARM, we run LINUX.

If DSP gets the flash access , then DSPLINK becomes unstable.
