Unable to read/write data on h2f_axi_master port

Hi everyone, 

 

I am trying to read/write data on avalon-mm port connected to h2f_axi_master port of hps on Cyclone V SoC device. But it does not work. 

But when I connect this avalon port to h2f_lw_axi port, it works well. 

Anyone who knows the problems, please show me. 

 

I really need to read avalon data on h2f_axi_master port. 

 

Thanks in advance!

use the following commands to check the status of the bridges, they could be stuck in reset. 

 

Command Description 

cat /sys/class/fpga/fpga0/status Determine the current FPGA state 

cat /sys/class/fpga-bridge/fpga2hps/enable 

cat /sys/class/fpga-bridge/hps2fpga/enable 

cat /sys/class/fpga-bridge/lwhps2fpga/enable Determine bridge status
