F28M35H52C: Using C28 DMA from EPI

Linda Zhang84708

Part Number: F28M35H52C

Hello Champs,

What about the limitation of using F28M35 C28 DMA to read data from EPI?

If using CPU Timer interrupt to trigger C28 DMA to read data from EPI, how fast can it reach?

Thanks!

Best Regards,

Linda

Linda,

What kind of memory is being accessed through EPI? Do you know the word size?

Is there concurrent access to EPI from other masters?

When the errors are observed, is the data transferred using an uninterrupted routine without a CCS memory or expression browser window open?

What is the error in this case? Not clear from the message.
