pcie dma error on intel fpga

hi,Jesus

We are using an Arria 10 GX FPGA accelerator board for the data center. There is a problem with dma reading and writing when using it now。

Board information and application scenarios can be found here

大家好

我们在“Linux 5.4.0-77-generic #86-Ubuntu SMP Thu Jun 17 02:35:03 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux”环境下使用A10卡，安装驱动后，测试DMA读取写入函数，
1.我们环境中的驱动成功安装机器，如图1所示。
2.图2挂机时的截图3.写了一个简单的启动测试dma读取8192字的程序
第一次读没，第二次读后又挂了，开始程序启动的过程。，图3是一个简单的测试过程

Hi liny,

Thanks for reaching out, could you please share a link to the Edge Use Case that you are using with your FPGA device? Is this from Edge Software Hub?

Hi liny,

I moved your post to the FPGA forum for the appropriate team to answer your question.

Hi,

May I know what type of design have you programmed into the PAC card?
