Part Number:AM5728

Hello, TI Experts,

Our customer sent us question about PCIE of AM5728.

They found unexpected behavior like below with their product by using AM5728.

- WORD(16bit) and BYTE(8bit) access from AM5728(RC) to their FPGA(EP) seems to be fail on their custom board.

   (DOUBLEWORD(32bit) access is success.)

- They also found below Errata.

     "i870 PCIe Unaligned Read Access Issue"

 

- The problem seems to be solved by applying the workaround2 in the errata.

     -They reported us that "WORD(16bit) and BYTE(8bit) access are also success."

 

Question:

Are there any notice or comment for this problem solving way by applying the workaround?

 

Best regards,
