一、下载XDMA文件 输入命令: sudo git clone https://github.com/Xilinx/dma_ip_drivers 二、编译文件 进入xdma文件夹: cd dma_ip_drivers/XDMA/linux-kernel/xdma/ 2. 编译文件: sudo make install 3. 如果提示错误应该是没安装make或者gcc编译器。 4. 输出信息 ubuntu@ubuntu:/usr/XDMA/linux-kernel/xdma...
HiFive Unmatched主板板载SiFive Freedom U740处理器。FU740是异构的多核处理器,它总共有五个核。它的五个核分别为四个U74应用处理器内核,以及一个S7嵌入式处理器内核。 作为RustSBI的软件实现开发者,我们注意到S7管理小核将有广泛的用途。因此,RustSBI在HiFive Unmatched上不屏蔽任何的核,以供操作系统选择和使用。
然后再运行install.sh脚本就可以安装了,绕过校验和检查。 unmatched上编译toolset并安装CPU2006的步骤总结 首先设置PERLFLAGS(参数供参考),执行buildtools脚本进行toolset的编译。 $ export PERLFLAGS="-A libs=-lm -A libs=-lc -A ldflags=-lm -A cflags=-lm -A ccflags=-lm -A ccflags=-fwrapv -Dlibpth=/...
Hi. Received my Unmatched today and it seems to be working fine, but I’m a bit disappointed that the “reboot” command does not work. reboot used to work on the Unleashed, but then it broke in the whole OpenSBI kerfuffl…
I must admit that I never use github. I was able to work with gcc/gdb directly on Unmatched board (Ubuntu) but my main tool to develop is Xcode. My goal is to try cross-compile-debug on my Mac since I have a very limited experience with Linux. ...
Hi all, I’m trying to set up target debug of the Linux kernel using GDB & OpenOCD of the HiFive Unmatched. I’m running an Ubuntu 20.04 host. I’m using the stock build from the SiFive freedom-u-sdk github with just tw…
Despite, as i think, this is quite obvious, some people miss the point. So let me show you how to unbrick the HiFive Unmatched board, that’s useful in case of: installing BSP without the need of preparing the SD card …
