NAND Flash Read/Write and Timer Problem

Ada NGAN
Prodigy 110 points

I am using the LCDK6748 development kit for my C6748 development.

Currently, I try to write/read data into/from 4G 16-bit NAND flash in the development kit, by using the NANDOpen, NANDPageWrite, NANDPageRead (take nandWriteRead.c from Starterware for reference). And, it works properly.

However, when I embedded the NAND flash program codes into my CCS5 project, the Timer2 and RTC fail to work. Seem, there are some crashes between NAND flash DMA access and Timer/RTC interrupt handling.

Did anyone encounter this kind of problem before? Please kindly advise how can I solve the captioned problem.

Thank you so much and look forward to all of your reply.

Best Regards,

Ada

    By the way, how do you test the Timer2 and RTC? By some chance if you flash the test executables of Timer and RTC into NAND memory and then run the nand starterware examples, most likely, when it performs the erase operation, it will erase the executables flashed into it. Did you happen to do this way?

    Would you please brief how do you observe the crashes? How do you test it? The starterware examples of timer and RTC works properly for you?

    What do you mean by embedding the NAND flash program? Do you mean importing the NAND starterware example program?
