I'm using the watchdog timer to generate a NMI interrupt so that i can save something before my system reset(doing reset in NMI ISR). But whlie I made some file operations(like adi_FileOpen,adi_FileWrite, etc...) in NMI service routine, error ocurred! I even could not get out of the first file operation such as adi_fileopen!
Cannot I make some file operations in the NMI ISR?
By the way, I'm using the VisualDSP++ update 6.
thanks for all replies！
