HPS Linux in Putty will freeze after programming FPGA on DE1-SoC

Jump to solution

I am doing my project which using FIFO bridge to transfer data between HPS and FPGA on DE1-SoC. Recently I am facing a problem, after I program the FPGA, the linux will freeze, I am using Putty. Previously I have no this issue.

Sometime it will still work after I program the FPGA( after I power off and on the board), but once I run the executable file, it will freeze again.

I have tried to run the previous project that can run without problem before, but still, it will freeze.

It is very urgent, may I know is it something wrong with the board?

Hello,

You can refer to this link for the sdcard layout and the contents of a complete image:

https://rocketboards.org/foswiki/Documentation/AVGSRDSdCard

 

For the uboot script, you can refer to this link:

https://rocketboards.org/foswiki/Documentation/GSRDProgrammingFPGA

 

Hope this might help.

 

Thank you.

Hello,

Are you programming the FPGA while linux is running?

If yes, then it is expected to see abnormal behavior of the system (like the freezing issue).

You can program the FPGA via to valid ways:

1- through uboot.

2- via device tree overlay.

 

Method one is easier and straightforward. you need to provide your system with the rbf file (FPGA image), and a scr file to make uboot reads the instructions.

 

It is not recommended to program the FPGA directly while linux is running on ARM.

 

Thank you
