Does pynq petalinux config suspend spidev

I am trying to build PYNQv2.4 image on other zynq7020 board with base vivado project that includes AXI SPI ip( PS use spidev driver to read/write by emio).

I have successfully tested it on Petalinux,so I write extra kernel config to metapynq:

system_dtb.txt (13.6 KB)

Spi devicetree is generated in system.dtb as before, but the linux occurs error:spidev spi0.1: SPI transfer timed out.
I also tired to use my previous successful petalinux project to adopt pynq, writed extra kernel config:


With xlnk device tree, it can run with pynq filesystem, using functions such as ‘import pynq’ , ‘pynq.Overlay(‘bit’)’ and spidev, but error occurs in Partial Reconfiguration:

/usr/local/lib/python3.6/dist-packages/pynq/pl_server/ in download(self, bitstream, parser)
578 fd.write(flag)
579 with open(self.BS_FPGA_MAN, ‘w’) as fd:
→ 580 fd.write(bitstream.binfile_name)
582 super().post_download(bitstream, parser)

TimeoutError: [Errno 110] Connection timed out
Any suggestion is appreciated.
