Other Parts Discussed in Thread: C2000WARE
Hello,
I am using the TMDSCNCD28379D control card to control my converter and found the system would behave differently with the code running in RAM and FLASH.
When I was running the code in RAM using CCS8, the system would work very well. The system works under both rated input voltage and half rated input voltage conditions.
When I was running the code in FLASH using CCS8, the system control loop would run away at half rated input voltage.
When I was running the code in FLASH using CCS10, the system works at half rated input voltage. But the system control loop would run away at rated input voltage.
My guess is that there might be some project configuration difference that caused this problem. But I checked project configuration of each project, no much difference is found.
Part of the project files are put in the attachments. Pictures of my control card used for test is also shown. When I runs the code from FLASH,SW1 on card is switched to mode 03. When I runs code from RAM, the SW1 is switched to mode 01.
Could you please help me figure out the problem? Thanks
