Code or the compiler issues?

Hi,

On looking at your code real quick I see the dma doing something which creates this issue.

I do not have a definite explanation yet, but without the delay routine, I believe DMA gets reprogrammed again for it to not do what it would have done otherwise(Its purely a hunch based on the time I spent debugging this).

I see there are few errors due to FMC correctable/un-correctable errors due to which the error led pop's up. On investigating I see the fault addresses from FMC module to be 0x8xxxx, which obviously do not have the ECC programmed as it does not have valid code as far as your .map file is concerned.

Hope this helps for now.

Thank you for your reply, but it will work well with keil.

I will check the code for DMA, Thank you

I have tried to solute the question for one day ,but  still have no method to solve,I  think the code have not  problem, but it  still don't work well. Any other suggestions?

Thank you!

Is it right that DMA can not use "AUTOINIT" if I send no fixed number data?

Hi,

I'm still looking in to your code to understand what you are attempting. In fact I will request our Mibspi expert to have a look in to this as well. Thanks.

HI:

Can you send to export of your DMA quikly?

The project is very anxious，Thank you very much
