PRU loading at boot time

Other Parts Discussed in Thread: OMAP-L138

Hi,

I'm aware of the Linux PRU loader but I'm actually looking for loading a PRU instruction set on an OMAP-L138 at boot time from UBL.
I have an instruction set assembled using PASM in form of a C array.

What is the best way to achieve memory transfer to PRU's Data RAM from UBL? Is it as simple as copying the array at address 0x01C30000
or should I need to use a serial protocol?

There is a very basic PRU loader included with Sitaraware. This doesn't have OS dependencies. So I think you can quickly adapt the C code to work in your boot environment.

Regards.

Sorry, I was wrong here. There is no PRU loader in Sitaraware yet.

Actually the code I used was from the PRU development package. See PRU Software Development_1_03\host\common\

Hope that helps.

Regards.
