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
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?


Regards,

Hi,


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