- JC 04:31 PM Software Development: RE: Using McASP Rx clock generation module
- Ideally you should get it working from the baseboard as that should be the source of all the pinmux settings. Not sure what else might be overriding things. I have run into cases where i had multiple pinmux configs overriding each othe...

- Hi Jonathan,
Ok, good suggestion... thanks... the pinmux read
PINMUX0 = 0x8811.1110
so it's not getting set to ACLKR, instead to PRU0_R31[22], not even a gpio, which interesting.
PINMUX1 = 0x8888.8881

As some of you may know, I've been working on a MityDsp-L138F SoM, and I also have a custom designed board based on MityDsp. So far, I've used Linux on the Industrial IO board with kernel and file system installed on NOR and NAND ...

0x01C14124 - PINMUX1

So I have updated the baseboard-industrialio.c to enable all of the baseboard_mcasp_pins (like the ti evm) and even took out the GPIO configs for 13 & 15 which certainly can get overridden later, just ... - MW 09:32 PM Software Development: RE: Using McASP Rx clock generation module

Have you checked the pinmux settings for the IO Pin are set to use the McASP function and not GPIO or something else?
The only option (what we do) for probing even pins on the connector is to tack a small wire on the edge c... - TR 09:24 PM Software Development: RE: Using McASP Rx clock generation module

We are working thru enabling of the McASP Rx clock generator module. After making source updates to davinci_mcasp.c we've been successful in generating a frame clock (AFSR) and see it's output on omap_gpo_13, but we cannot observ...
