program auto reboot,without watchdog?why?

I have used DSP for several years, but I even did not know how to make DSP Chip reboot except Reset the Chips.

I know only one way to reset DSP chips only with Watchdog, but My program did not enable watchdog which I am very sure.

What is the direction to resolve the problem?

thank you.

Hi Thomas,

my board boot mode is SPI mode,my program has been burned into SPI flash,after power on, program
    start to run, and every thing works well, but after some operation, the C6747 will reboot again,

At what situation or type of access, the board get RESTARTED ?

Is that reproducible ?

Try to debug your code through emulator on CCS.

Until now, I find two acess can lead the CHIP restart, one is related with SPI Flash and Uart, another related with

timer and Uart.

they are reproducible, but although the use same acess, the restarted at differ time, for example, this time will restart after access 30s, another maybe 50s.

so,what can I do?

oh，there is another important tips that when I use CCS to debug the program，the Chip also will reboot after the same two operation， the appearance is same as above。

whenthe Chip also will reboot， the CCS emulator did not disconnect，and check the RAM region and can find the RAM data is same witch SPI Flash program context。

what should I do，next？Does it means the Chip did not reset  whenChip reboot， the CCS emulator did not disconnect ？

Hi Thomas,

Could you please attach the screen shot of the reset while you debugging through CCS ?

Also attach your linker command file.

Hi Thomas,

I'm glad that you were able to fix the problem.

Thanks for your update.
