RTOS/TMS320F28075: Sys/Bios Timer seem not running at all

Hi Jeanluc,

Can you tell me which SDK version you are using?

Additionally, could you post a screen shot of the 'Clock' view in ROV before and after you start the application in debug mode? If you can, the 'detailed' view has the most info.

I noticed that your clock0 is defined to run myclk() and not myTimer() but maybe that is what you meant. Also, you may want to remove the duplicate System.SupportProxy definitions, to make your cfg more straight forward.

Thanks,

Sean

Sean,

Thank you so much to reply

My CCS is 9.0.1.00004  / Bios 6_76_00_08

I want to use the sys clock with the function call "myclk" see my .cfg , and I defined Clk0Fxn and Clk1Fxn in the main,  the first figure is before start ( still first break point in Main)  and second figure is running after few second ( notice tRemaining is not moving ) the tick clock seems  not running  at all . I want to understand why Clk0Fxn  and Clk1Fxn are not working myClk , I also created myTimer as test only  and it's not working as well, something is wrong with my setup. Timer"xx"_ISR seems to work.

Hi Jeanluc,

Thanks for getting that information for me. Unfortunately the links to the pictures appear to be broken. Instead of the pictures, I see little 'broken link 'icons. Do they show up in the forum for you? If not, could you reupload them or maybe upload them to a third party image host like imgur.com and post a link to that here?

Thanks,

Sean

Just found a new issue with Semaphore , I set everything and I when  Semaphore_post the semaphore the Fxn attached to the Semaphore ( Waiting thread)  is cleared . see the picture

Sean

I agree with you I should start from scratch, but I don't have any example to start with

I don't have SYS/Bios in Resource Explorer   I don't know why

Thanks
