Hello, 

I am having some difficuties with the DMA, and I would appreciate if somebody could help with the following doubts:

1) What should be the  source to be choosed in a channel, if the request is comming from the major loop link of the previous channel? Any of the differents 'always on' source?

2) At the end of the following post, Help - continuous DMA with PIT , it says that there was a bug in the silicon when using PIT wiht 'always enabled' request. Is it fixed already?

Thanks for your help.

Hi AITOR ARANZABAL,

I've not found this bug record in errata of K64_120, so I think this errata is fixed now.
Have a great day,

Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
1) What should be the  source to be choosed in a channel, if the request is comming from the major loop link of the previous channel? Any of the differents 'always on' source?
-- Yes, any one of 'always on' sources is Ok.
 2) At the end of the following post, Help - continuous DMA with PIT , it says that there was a bug in the silicon when using PIT wiht 'always enabled' request. Is it fixed already?
-- Before answering your question, I think you'd better tell me which chip you use.
Have a great day,
TIC
