Failed to perform the AXI DMA read-write transfer: Timer expired

[Feesics]

when I use petalinux2019.1 and linux-xlnx-xlnx_rebase_v4.19_2019.1, and execute ./axidma_benchmark -b 16384 -s 16384 or ./axidma_transfer 1.txt 2.txt, there is a problem that is "Timer expired".

And there is my block design and device-tree (pl.dtsi and system-user.dtsi) in my project.
