Hi all

Please tell me memory map of i.MX7D.

Accroding to the section 2.1.2 Cortex-A7 Memory Map of IMX7DRM Rev. 0.1, 08/2016, the memory map has TCM region as follow.

Q1.

Is it a different TCM which is inplemented to M4 ?

Q2.

If Q1 is yes, could you provide me a block diagram which shows connection with A7 ?

I want to know the connection whether it connect bia L1 cache and L2 cache or not.

Q3.

If Q1 is no, can A7 access to the TCM ?

Hi Yuri

Thank you for reply.

So the TCM is implemented to only M4 and Cortex-a7 can access to TCM.

Am I correct ?
