Linux/PROCESSOR-SDK-AM335X: PRU control from kernel space

Diego Juara

Tool/software: Linux

Hello,

I'm using this system communicating the processor with the PRU's it has. I'm using the PRU Linux Loader (http://processors.wiki.ti.com/index.php/PRU_Linux_Loader) . The point is that this driver works on the userspace, but I need to control the PRU from the kernel. On that page, it show there is also drivers for the kernel, but when I enter into the link to the source code, the link takes you to an empty page (https://gforge.ti.com/gf/project/pru_sw/). Searching on the internet I've ound he app_loaer (which works in the userspace), but I cannot find anywhere the kernel_loader folder which contains drivers to control PRU from the kernel.

Thanks in advance.

Diego.

Hello,

I am not a PRU expert but have you checked this wiki pages:
processors.wiki.ti.com/.../PRU-ICSS_Getting_Started_Guide
processors.wiki.ti.com/.../PRU-ICSS_Remoteproc_Driver

Hope this helps.

Hi Margarita,

I'd seen these pages, but the problem is that I've part of the system made with the Linux Loader driver (in userspace), I want to use the same driver but with functions that works on kernel space. In the link I posted before aparently this exists, or a least, some time ago, but I can't find it.

Thanks for your helps.

Diego.

Hello,

As I said, I am not a PRU expert but since I know in the Processor SDKs the Remoteproc driver is used:
processors.wiki.ti.com/.../PRU-ICSS_Remoteproc_and_RPMsg

Hope this helps.
