hi3516开机修改内存和MMZ分配并安装SDK驱动

标签：MMZ mem blog details https article hi3516 com SDK

1. 拿到的开发版中已经安装最小系统，连接串口开机，设置启动文件

# 配置IP地址

ifconfig eth0 172.16.96.151 netmask 255.255.248.0

route add default gw 172.16.100.1

# 启动telnet服务

telnetd

# 启动ftp服务

inetd

 

# 挂载nfs文件系统

mount -t nfs -o nolock -o tcp -o rsize=32768,wsize=32768 172.16.96.85:/c/Deepin/share /mnt

 

2. 查看内存大小，注意系统内存MemTotal和可分配内存VmallocTotal，接下来进行系统内存和MMZ内存分配

cat /proc/meminfo

 

3.查看启动参数命令，注意系统内存mem，后面根据需要对其进行分配

cat /proc/cmdline

mem=64M console=ttyAMA0,115200 root=/dev/mtdblock2 rootfstype=jffs2 rw mtdparts=hi_sfc:1M(boot),4M(kernel),11M(rootfs)

 

3. 开机按任意键，进行启动参数设置，进行系统内存分配

setenv bootargs 'mem=256M console=ttyAMA0,115200 root=/dev/mtdblock2 rootfstype=jffs2 rw mtdparts=hi_sfc:1M(boot),4M(kernel),11M(rootfs)'

saveenv

reset

 

4. 重启启动后查看内存情况

cat /proc/meminfo

 

5. 安装SDK驱动，在提供的SDK中找到驱动文件，注意要和内核版本匹配，否则会安装失败。根据实际情况配置mem_total、os_mem_size、mmz_start、mmz_size

驱动文件位置：

3516DV300\Hi3516CV500R001C02SPC020\Hi3516CV500R001C02SPC020\01.software\board\Hi3516CV500_SDK_V2.0.2.0\package\mpp_smp_linux\ko

cd ../ko/

vi load3516dv300
