AB 07:23 PM Software Development: Pinmux changes back on its own
I'm trying to set up PINMUX5 at address 0x01C14134 to have EPWM1A on the output. It seems to take on the desired value momentarily, but the value subsequently changes back after only a brief moment. The following is the code that I'm using: Andrew Bean

AB 11:30 PM Software Development: Instructions to get going with the OMAP PWM
I'm trying to get EPWM1A running with the MityDSP-L138 module and MityDSP-L138 (F) Family Development Kit.
1) Is there a set of instructions or any discussion on using the PWM specifically for the MityDSP-L138? All I need is a square wa...

JC 02:53 PM Software Development: RE: Problems with the first time configuration
If this is the module that came with the devkit then it should boot into linux when powered on assuming you don't hit any keys during the boot loader stage.
If its just booting to the u-boot prompt it would be helpful to see the full ...

So, I've been playing around with the example code more to try to get the interrupt wait() and clear() to work.
This is how it is supposed to work:

This seems to be the same as one of the issues that Jonathan Cormier observed in the topic that you linked. E.g., "gpioToggle test passed when i just ran it. Not sure why." whereas he had earlier posted that it failed.

Andrew,
Another user was able to successfully run the demos on the MityDSP-L138, but perhaps they didn't test things as strenuously as you did.

I'm having multiple issues with the PRU example PRU_gpioToggle. In short, it seems like some read/write operations to memory mapped locations are not always executing properly. The two problem spots are the following:

DS 10:38 AM Software Development: RE: Emulator stops working very often.
We generally try to do as little as possible in main(). It should launch an initialization task and you would work from there.
If you do not need to debug initialization, sometimes it may be beneficial to allow the code to run (not h...
