Forum Post: RE: stack value change to 0?

Hello Thomas,

[quote user="thomas yang78259"] Today, I find thar the value of uartFifo[2] is {0, 0} when debuging a section of program,
   and then I think any stack of Uart_TSK1~Uart_TSK5 is Overflow, when the DSP/BIOS kenerl tell
   me all the TSK stack is normal, so I do not understand the question.[/quote]

I'm not sure I understand the question. You suspect there is a task stack overflow but when using KOV you see that it has not?

[quote user="thomas yang78259"]        while a second question, there is a Common sense debug with CCS, if the memory become red,
   it means the domain of the memory had been changed, but if some memory become light blue,what
   does it means to me?[/quote]

light blue represents contents of L1D cache

Thanks
