PinMux: Using the Generated Header Files

Mario Raffin

The Pinmux Utility is well described here for AM335x processors. Surprisingly the last section "Using the Generated Header Files" does not describe what to do with these files on AM335x. It is written "For other [other from AM35x / AM37x / OMAP35x] supported devices, the source code provides a complete description of all settings but is not directly usable as U-Boot source code.".

The e2e provides some solution but what I have found refers to previous releases of SDK and u-boot.

Now there is the Sitara SDK8 and u-boot-2014.07: what is the precedure to exploit the mux.h and pinmux.h?

Looking at the e2e it seems they are used only for kernel. Is it possible to set the pinmux in the u-boot?

Thank you.

Hi,

The pinmux tool you are referring to is the old version which is no longer supported. There is a new tool: http://www.ti.com/tool/PINMUXTOOL This is the current wiki page: http://processors.wiki.ti.com/index.php/TI_PinMux_Tool This tool is developed and supported by the CCS team. Any questions about it should be posted on the CCS forum: http://e2e.ti.com/support/development_tools/code_composer_studio/default.aspx

Thank you Biser.

I have just ported my old pinmux configuration in the new tool (v 3.0.625) and I have generated the files.

Still I have not undestood how to use them in u-boot and kernel. I will forward the question to the CCS team.

Regards,
