Hi,Yuri
Do you know something about cortex-M4 accessing fpga by EIM?
I have read the imx6sx.RM,but don't find the answer.
Looking forward your help!
Hello,
I am afraid, we do not have special example for CM4 using with the EIM.
You may look at section 23.7 (Typical Application) of i.MX 6SoloX Reference
Manual, Rev. 2, 9/2017 - how to configure EIM registers. It does not depend on what core is
accesses EIM: CA9 or CM4.
For CM4 addressing its mapping should be used, please refer to Table 2-2 (CM4 memory map).
Also, the RDC should be configured to allow CM4 access to EIM. Please use Chapter 52
[Resource Domain Controller (RDC)].
Have a great day,
Yuri

Hi,Yuri
How can I mapped the EIM address On CM4,while On A9,I can use mmap() the address(0X50000000) decribed in Chapter2
Hello,
it depends on application, working on the CM4.
Regards,
Yuri.
Hi,Yuri
Could you give an example for any address that CM4 can access FPGA by EIM correctly?
