AM335x PRU Examples

Micheal Donohuue

Hi,

I'm slightly confused by the examples given with the PRU software support package, is there a page on the wiki describing what each example does and how to use them? I'm trying to use the PRU_mem1DTransfer however when I attempt to load the firmware using remote proc I get the following error

[ 4.470748] remoteproc0: powering up 4a334000.pru0
[ 4.551371] pru-rproc 4a334000.pru0: rproc_boot failed
[ 4.605723] pru-rproc: probe of 4a334000.pru0 failed with error -12

Could I get some advice on how to evaluate this example application?

Thanks

Hi Biser,

I have already gone through the wiki and can't find any info. I'm look specifically for documentation relating to the PRU examples

Thanks

Hi Biser,

Sorry to be a pain but that still doesn't contain any information on the examples that are supplied with the pru-software-support-package. I want to know how the Linux side of the PRU_mem1DTransfer works and how to load the firmware using remoteproc

Thanks

Micheal
