The attached patch applies to iMX6_Platform_SDK for i.MX6 Dual and Quad and brings 2 additional SDMA memory to memory scripts:
With this patch, the new scripts are also integrated in the SDMA Test menu of the Platform SDK.
I created these scripts starting from the ROM script ap_to_ap. In order to dump the content of the SDMA ROM, I used mxc_printSDMAcontext function which is also included in the attached patch and can be invoked when needed.
Thank you for the post.
Are these ap_to_ap_fixed RAM scripts capable of accessing the external EIM bus?
Example: Main RAM to fixed address at EIM bus
Yes, it's in the ap domain.
