Pupanvr hardware and software board side development environment configuration (4)

         Run the compiler directly on the hardware C,C++ Warning message about incorrect version of Library , It seems that the compiler version is inconsistent with the current board end system , Need to update rootfs, Use the compiler's corresponding BSP package ：Hi3536C V100R001C02SPC040, Compile the rootfs, To facilitate development , Use jffs2 File system .

• Partition configuration :

mem=300M console=ttyAMA0,115200 root=/dev/mtdblock2 rootfstype=jffs2 rw mtdparts=hi_sfc:1M(boot),4M(kernel),11M(rootfs);

• BSP compile

  decompression BSP After package , stay Hi3536C V100R001C02SPC040\01.software\board find Hi3536CV100_SDK_V2.0.4.0.tgz, Unpack , Execute in the directory ：sdk.unpack.

reference osdrv\opensource\kernel Explanation , hold kernel Download and unzip , Fix the patch , Back to osdrv Under the table of contents , An Zhao readme_cn.txt Description compilation .

In my ubuntu20 Tips mkimage Can't find , This one uses apt-get Just install the corresponding tools .

When compiling to the file system mtd-utils1.5.0 Will compile but , The record of how it was handled a few years ago is updated to 1.5.2 It's a good version .

Misunderstanding mainly means that you can't find major,minor These functions , This time, we corrected the mistakes , In the corresponding file  #include <sys/sysmacros.h> Statement , There are also hints zlib The header file for cannot be found , Modify the corresponding Makefile, Because you only need mkfs.jffs2, Make sure that this tool has not been changed after it has been compiled , Make up mkfs.jffs2 after , Kao to osdrv/pub/bin/pc/mkfs.jffs2.

• reference SDK The way in the world , Pack it up rootfs:

osdrv/pub/bin/pc/mkfs.jffs2 -d osdrv/pub/rootfs_glibc -l -e 0x10000 -o osdrv/pub/rootfs_glibc_64k.jffs2

• stay ubuntu Install it in the middle tftpd-hpa Service for ;
• Into the plate end uboot In command , Configure the relevant ＩＰ Address ;
• adopt tftp,sf Write a fever under the tool rootfs, Like my environment :

tftp 0x8200000 rootfs_glibc_64k.jffs2;

sf probe 0;sf erase 0x500000 0xb00000; sf write 0x82000000 0x500000 0xb00000;

         After entering the system, set up IP, mount To uboot Of NFS Catalog , The running program did not report an error .

       

• MPP Environment configuration ;

hold Hi3536CV100_SDK_V2.0.4.0\mpp\ko Put the directory into the mount directory , Execute at the board end , Dan Bao Unknown symbol devm_pinctrl_put These modules are wrong , It seems kernel It's better to update it .

First put the end of the plate kernel The backup to come out , Update again kernel.

Direct use BSP Compiled in Kernel Can run normally , The Internet is normal , It seems lucky , Manufacturer and official DEMO A little change , Then execute the following script .

 ./load3536c -i -total 512 -osmem 300

MPP Corresponding to ko All loaded .

With these environments , You can basically develop all business functions on this board , hold SDK Inside mpp The driver 、 Copy to ubuntu Under the mount directory of , You can load it by command ！
