Hi3531D系统移植

Posted 2022-08-22 旧年不在cd

一、编译系统

make OSDRV_CROSS=arm-hisiv600-linux PCI_MODE=master FLASH_TYPE=spi all make OSDRV_CROSS=arm-hisiv600-linux PCI_MODE=master FLASH_TYPE=spi all

二、u-boot下配置网络

setenv serverip 172.18.171.16
setenv ipaddr 172.18.171.201
setenv ethaddr 00:00:00:12:23:33
setenv netmask 255.255.255.0
setenv gatewayip 172.18.171.1
saveenv
ping 172.18.171.16

三、USB下载

usb reset
fatload usb 0 0x42000000 image_glibc/u-boot-hi3531d.bin		
sf probe 0
sf erase 0 100000
sf write 42000000 0 100000

fatload usb 0 0x42000000 image_glibc/uImage_hi3531d
sf probe 0
sf erase 100000 400000
sf write 42000000 100000 400000

fatload usb 0 0x42000000 image_glibc/rootfs_hi3531d_64k.squashfs
sf erase 500000 1200000
sf probe 0
sf write 42000000 500000 1200000

四、设置环境变量

setenv bootargs 'mem=256M console=ttyAMA0,115200 root=/dev/mtdblock2 rootfstype=squashfs mtdparts=hi_sfc:1M(boot),4M(kernel),14M(rootfs),2M(config),27M(app),1M(logo),15M(rsv)'
setenv bootcmd 'sf probe 0;sf read 0x42000000 0x100000 0x400000;bootm 0x42000000'
saveenv

五、挂载

ifconfig eth0 172.18.171.30 netmask 255.255.255.0
route add default gw 172.18.171.1
mkdir /var/guchunqi
mount -t nfs -o nolock 172.18.171.38:/home/guchunqi/ /var/guchunqi
cd /var/guchunqi/

六、烧写logo图片到flash的logo分区

usb reset
fatload usb 0 0x44000000 logo.jpg
usb stop

tftp 0x44000000 logo.jpg
sf probe 0
sf erase 3000000 100000
sf write 44000000 3000000 100000

七、设置logo图片解码参数

setenv jpeg_addr 0x44000000
setenv jpeg_size 0x114ac
setenv vobuf 0x44800000
saveenv

setenv jpeg_size 0x8d9d
setenv jpeg_addr 0x44000000
setenv vobuf 0x44800000
saveenv

八、u-boot命令行下显示logo

sf probe 0
sf read 44000000 3000000 100000
decjpg
startvo 0 4 12
startvl 0 0x44800000 1920 0 0 1920 1080
