any example code for connecting uart with edma on keystone platform

Yuan,

That's the only example code w/ have for UART on C6678.  You can use it as a baseline for creating your code.  The UART IP's differ between the L138 and Keystone (C6678 for example) devices.  While there's probably some programming similarities from the CSL code, I cannot guaranty that it will work.

Hi,

Iam also using the EDMA example code for c6678, Between CSL and LLD which one is the preferred method for keystone devices.

Please let me know.

That would be user preference, there are benefits to each.

LLD gives you a bit higher level abstraction and may not be quite as efficient as possible, but you it's less work for the user.  The CSL's are very low level and but allow you do tailor it to your system more efficiently.

Best Regards,

EDIT: Corrected my earlier comments.

Thanks for the info Chad, Could you also point me if there is any examples for using IDMA in c6678 devices.

There are examples available in the PDK.

Hi, Chad,

I am trying to mannualy connect the interrupt for the uart, such as THREINT and RDAINT manually with my isr in sysBios, but from TMS320C6657-2.pdf, sprugw4a.pdf nor from sprugp1-2.pdf, I could not find them. How can I find which interrupt it is so that I can connect an isr?

thanks
