Our customer have some questions about i.MX6UL SDMA and EIM.
Please see the questions as below.
Please see chapter 22.214.171.124 in IMX6ULRM (Rev.1).
It says that peripheral DMA unit does not support burst transfer.
And according to https://community.nxp.com/message/546378, peripheral DMA can be used for EIM.
Then, if our customer use this peripheral DMA for transfer to EIM memory region, the EIM bus access will be single access even though EIM is synchronous mode?
How can we use peripheral DMA from ARM to EIM or vice versa?
With i.MX6DQ, SDMA script written in Appendix A of MCIMX6DQRM can be used for SDMA transfer.
However, there is no the appendix in MCIMX6ULRM Rev.1.
Should we refer the code in chapter 126.96.36.199.1 of MCIMX6ULRM instead of SDMA script?
Or SDMA script can be used for i.MX6UL also?
