- 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 ... - HB 02:06 PM Software Development: RE: Problems with the first time configuration

I'm using now TeraTerminal, my serial port is working OK and I got in the U-Boot prompt, I checked the configuration of the Network Adapter of the Virtual Machine and is set up like a Bridge.
I tried to ping the VM I...

This is how it is supposed to work: - AB 02:00 PM Software Development: RE: PRU_gpioToggle example fails sometimes

- 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.
As for trying t... - BD 10:30 PM Software Development: RE: PRU_gpioToggle example fails sometimes
- 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.

Regarding point 2, ... - 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:

Sorry about all this. I am going to see if someone can add some detail to the Quick start guide about initial power on. Hopefully will work on it on Monday.
