Part Number: AM5728
Hello, TI Experts,
Our customer plan to use AM5728 for their product.
And they sent us the question about PCIE performance of AM5728 by using TI-RTOS(PROCESSOR-SDK-RTOS-AM57X).
We found related wiki site like below for K2G(It seems to use Linux).
Is there any other appropriate document/web-site for PCIE performance of AM5728 by using TI-RTOS(PROCESSOR-SDK-RTOS-AM57X).
If there are any difference/notice to use this wiki-site PCIE performance information to AM5728, please also tell us.

In reply to lding:
Thank you very much for your detail explanation.
I really appreciate your help.
I'd like to share the checked result below. (please refer the pdf in detail.)
- Set a breakpoint here and check the value of ibCfg.ibOffsetAddr.
-> We found "ibCfg.ibOffsetAddr=0x81082CD0".
The address seems to be "DDR".
- Set a breakpoint, check the remoteBuf value.
-> We found "remoteBuf=0x21000A00".
The address seems to be "PCIE_SS1".
So, our understanding is as follows;
- pcie_sample.c : EDMA read demo
- EP read from DDR & the data is transferred to RC.
- RC write to PCIE_SS1.
- Is this understanding correct?
- Could you tell us the next/final destination of the data of PCIE_SS1 written by RC like above.
-> Is Final destination DDR on RC?
Thank you very much for your kindness.
I checked the value of "source" like below. (please refer attached pdf)
- source=0x81069400 (it seems to be an address in DDR as you said.)
And our customer sent us additional questions like below;
- 1: Could you explain the below definitions?
#define PCIE_IB_LO_ADDR_RC 0x90000000
#define PCIE_IB_HI_ADDR_RC 0
-2: Are there any document or guide of below registers?
- They would like to know how to configure those registers and recommended configuration.
