How to implement EIM with SDMA on a i.mx53 device?

[mariusmüller]

Hi,

Can anybody help me how to implement External Memory Interface Driver with SDMA? An example code for Windows Embedded Compact 7.0 would be really helpful.

Thanks a lot.

Cheers

We don't have much document talk about SDMA script. I think you may take the mxc_sdma_test in imx-test package in Linux BSP for an example. And you can read this for reference. https://community.freescale.com/message/301919#301919

That link (https://community.freescale.com/message/301919#301919) doesn't work. Is that document available elsewhere?

Thanks a lot. I forgot to say, that I want to implement it on Windows Embedded Compact 7.0. I don't have access to this https://community.freescale.com/message/301919#301919 URL.

Please find attached sources used for mx51_SDMA_ap_2_ap_fixed, one can use them

for WinCE scripts writing, hope this helps.

Oh, sorry, I don't have document for WinCE7. The link https://community.freescale.com/message/301919#301919 contain a document that also is for linux.
