Other Parts Discussed in Thread: C2000WARE

DEAR ALL,

WE ARE USING TMS320F28377D CONTROLLER IN OUR SYSTEM.

WHEN WE USE DEBUGGER AND GIVE RUN COMMAND THEN PROGRAM RUNS OK .

WHEN WE GIVE POWER CYCLE AT THAT TIME CONTROLLER IS NOT COMMING OUT OF BOOT MODE.

WE HAVE OBSEVED VOLTAGE AT XRS PIN OF CONTROLLER AND IT WAS GOING DOWN AGAIN AND AGAIN EVEN WHEN WE HAVE PULLED IT UP AND CONTROLLER IS RESETTING IT UP AGAIN AND AGAIN.

please suggest solution as soon as possible.

Hi,

Is this custom application or you are trying any example from C2000Ware SDK? If you are trying example from C2000Ware SDK, then are you using CPI1_FLASH build configuration?

Please refer to this link which goes over the changes needed from RAM to Flash.

Dear sir,

we are having customer application developed and we are already running code in flash.

we have already develop code and it was running since 6 month in our factory .

now when we add any variable at that time controller is not coming out of the boot mode.

when we have changed compiler version to 22.06 from 21.06 and then problem solved .

but when we added mode variables then again same problem repeated.

Vishal,

Do you know if you have Watchdog enabled during boot time? If it is enabled, can you disable during init time, and then re-enable after it boots in main()?

What are the changes you are doing when it stopped working?
