编译和运行VCK190 TRD 2022.1

环境

参考设计： VCK190 Base TRD 2022.1
代码： https://github.com/Xilinx/vck190-base-trd
文档： https://xilinx.github.io/vck190-base-trd/2022.1/html/intro.html
工具版本: Vivado/Vitis 2022.1, PetaLinux 2022.1
开发板： VCK190 Production Version

编译

OS

强烈推荐使用Ubuntu 18.04、20.04。
请按照UG1144要求进行设置，和安装OS的软件包。

Shell

使用Bash作为system shell，不使用Dash。也就是“"/bin/sh"”应该指向bash。否则可能遇到错误"/bin/sh: 1: source: not found"。使用命令“sudo dpkg-reconfigure dash”更改。
更改Shell后，最好清除整个工程，然后从头编译。如果不清除整个工程，可能遇到错误，比如“cp: cannot stat 'aie/ip/libadf.a': No such file or directory”。

lrwxrwxrwx 1 root root 4 Aug 30 09:03 /bin/sh -> bash

make命令

不能使用“make all”，要使用下列命令。

make platform PFM=vck190_mipiRxSingle_hdmiTx
make overlay PFM=vck190_mipiRxSingle_hdmiTx OVERLAY=xvdpu
make sdcard PFM=vck190_mipiRxSingle_hdmiTx OVERLAY=xvdpu

建议使用脚本编译。下面是一个可以使用的脚本。

#!/bin/sh

# nohup

GCC版本

如果使用Centos 7，自带的GCC版本太低，需要在“petalinux-config”中使能选项"Enable buildtools-extended"。
Ubuntu 18.04带的是GCC 7.5.0。
更改GCC后，最好清除整个工程，然后从头编译。如果不清除整个工程，可能遇到错误，比如“ uns_test.c:118:5: error: ‘for’ loop initial declarations are only allowed in C99 mode”。

Csh shell

使用Tcsh作为Csh shell。否则会遇到错误"compile_ip.csh Word too long"。命令如下：

sudo apt-get install tcsh
sudo update-alternatives --config csh

记录如下：

hankf@XSZGS4:sxvdpu$ sudo apt-get install tcsh

NFS目录

有些服务器的存储使用NFS实现，导致PetaLinux报告错误“tmp can't be located on nfs.”。一般来说，服务器的目录“/tmp/”还是本地硬盘。使用命令“petalinux-config”, 在“Yocto Setting”中，更改TMPDIR为目录“/tmp/”的一个子目录。

生成wic映像

PetaLinux生成wic映像的命令是“petalinux-package --wic”。但是它不会包含额外文件，比如VCKTRD中的kernel文件“binary_container_1.xclbin”。
如果缺少文件“binary_container_1.xclbin”，运行时会遇到错误“ Check failed: fd_ > 0 (-1 vs. 0) , open(/boot/binary_container_1.xclbin) failed”。

使用下列命令，能在wic映像文件中包含kernel文件“binary_container_1.xclbin”。

petalinux-package --wic --bootfiles "BOOT.BIN boot.scr Image ramdisk.cpio.gz.u-boot binary_container_1.xclbin"

运行

System Contoller 和BoardUI版本

建议使用最新版本。这次运行使用的是2021.2，对应的文件是xtp613-vck190-bit-c-2021-2.pdf， rdf0574-vck190-bit-c-2021-2.zip， sc2.2_01.img.zip。

单板设置

按 https://xilinx.github.io/vck190-base-trd/2022.1/html/run/run-setup.html，完成下列设置

去掉J326 (7-8) 的跳线帽.
在BoardUI GUI的“System Contoller”的“Set VADJ”的“Boot Up”里，设置FMC电压是1.2V，而且读回来也要是1.2V。VCK190掉电重启后，读回来也要是1.2V。在使用2020.2的BoardUI版本时，没有读回来电压，应该是没有设置成功，导致后续i2c操作失败，Linux报告错误“imx274_read_mbreg : i2c bulk read failed, 300e (2 bytes)”。

电脑区域设置

建议Regional Format使用"Recommended [English (United States)]"。
电脑是Windows 10 英文版。当Regional Format使用"Chinese [Simplified, Singapore]"时，BoardUI报告执行脚本错误。在目录vck190_bit\BoardUI\tests\VCK190\logs下的log文件中，能找到详细错误“'ascii' codec can't decode byte 0xd6 in position 10”。更改Regional Format设置后，错误消失。

System Contoller的start_boardframework

2020.2的start_boardframework的脚本如下

root@xilinx-vck190-SC-2020_2:~# cat /etc/init.d/start_boardframework.sh
echo "******************************************************"

运行2D Filter

2D Filter的demo使用了Jupyter Notebooks。打开Jupyter Notebooks后，每个cell前面有“[]”，标识cell还没有运行。每个cell前面有“[]”，标识cell还没有运行。点击 ‘Kernel’ → ‘Restart Kernel and Run All Cells’ 后，cell前面变成“[*]”，表示正在运行。运行完成后，“[]”会多一个数字，如“[1]”、“[2]”，其中的数字表示运行顺序。cell下也可能有运行时的输出信息。

其它

如果运行异常，建议检查dmesg，看其中是否有错误。也建议先验证V4L2设备，看其能否采集视频。
