Compiler/TMS320F28379D: PWM is not working in Flash Standalone but working in Flash Debug mode

Due to holidays, you can expect a response in the fir week of January 2020.

Vasim,

Did you confirm that application started executing from Flash in standalone mode? Do you have boot mode pins configured for Flash boot?

Please check if you have any content mapped to RAM in your linker cmd file.  All initialized sections should be mapped to Flash for load and copied to RAM at run time.

Thanks and regards,

Vamsi

Hi Vamsi,

Application is getting started in standalone, since LED toggling, Communication is happening.

Linker file are attached

Vasim,

Do you have any IPC communication between the two cores?  If yes, did you check if there is any difference in the code (# defines, # if else etc.) between debug and standalone builds around that code? 

If you have IPC communication between the two cores, please toggle a GPIO or use some other mechanism to know whether both cores went past through that or not.  I am wondering if the core is waiting on the other core. Please check.

Thanks and regards,
