Dear All,

 

I want to read/write large TLP packet.

I read this post.

https://community.nxp.com/message/350342

It have been concluded that max payload is 128 byte.

 

I understood CX_MAX_MTU, CC_SLV_MTU and CC_MSTR_BURST_LEN are fixed.

If I change Max_Payload_Size and Max_Read_Request_Size in PCIE_RC_DConR, then can I process TLP packet including 512 byte payload with PCIe in i.MX6?

 

Best Regards,
