AB 07:27 PM Software Development: RE: PRU_gpioToggle example fails sometimes

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: Andrew Bean

In @static int LOCAL_exampleInit ( unsigned short prunum )@ of PRU_gpioToggle.c we need to have Andrew Bean

So this is strange. I modified the gpioToggle code to have the following: Andrew Bean

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... Andrew Bean

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.

AB 07:53 PM Software Development: PRU_gpioToggle example fails sometimes

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:
1) In the exampl... Andrew Bean

Hi Jonathan,
I imagine that you always work with more experienced users :D , but I'm just starting with this kind of systems, I will be waiting anxiously for the post.

Hector,
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.
In the meantime we usually use putty or teraterm for accessing t... Jonathan Cormier

Found this TI wiki. It appears that you must use the username anonymous with a blank password.

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... Dave Stehlik

Various small errors contributed to the problem. things seem to work better now. I can send & Recv 3 messages and I discovered the debugMsg print queue as well.

I think these are the files you need. Basically, just the HelloWorld files. Let me know if you need anything else. Edwin McKay

Would it be possible for you to post a copy of your example code, including the BIOS configuration files?
If you want you could send it directly via email offline...

We've run into a similar problem here and rebuilt the package ourselves.
As a quick fix I've attached the package file. Install with Gregory Gluszek
