For XM boards with Hi35{16Ev200,16Ev300,18Ev300} SoC ONLY!!!

Other boards may have different memory layout like HI3518Ev200 uses 0x82000000 instead 0x42000000

Supported sensors

Please look up your sensor in the list of supported devices.

Initial device firmware updates

setenv bootargs 'mem=${osmem:-32M} console=ttyAMA0,115200 panic=20 root=/dev/mtdblock3 rootfstype=squashfs init=/init mtdparts=hi_sfc:256k(boot),64k(env),2048k(kernel),5120k(rootfs),-(rootfs_data)'
setenv bootcmd 'setenv setargs setenv bootargs ${bootargs}; run setargs; sf probe 0; sf read 0x42000000 0x50000 0x200000; bootm 0x42000000'
setenv uk 'mw.b 0x42000000 ff 1000000; tftp 0x42000000 uImage.${soc} && sf probe 0; sf erase 0x50000 0x200000; sf write 0x42000000 0x50000 ${filesize}'
setenv ur 'mw.b 0x42000000 ff 1000000; tftp 0x42000000 rootfs.squashfs.${soc} && sf probe 0; sf erase 0x250000 0x500000; sf write 0x42000000 0x250000 ${filesize}'
saveenv

setenv soc hi351xxxxxxx          # Set your SoC. hi3516ev200, hi3516ev300, or hi3518ev300.
setenv osmem 32M
setenv totalmem 64M              # 64M for hi3516ev200, hi3518ev300, 128M for hi3516ev300.
setenv ipaddr 192.168.1.10
setenv serverip 192.168.1.254    # Your TFTP server IP address.
saveenv

run uk; run ur; reset            # Flash kernel, rootfs and reboot device

Follow-up quick updates

run uk; run ur; reset

Executing a command after the first run

For a Hi3516Ev300 board:

set_allocator cma
firstboot

For a Hi3516Ev200 or Hi3518Ev300 board:

set_allocator hisi
firstboot

Danger zone

You always have an option to update the bootloader. However, you need to understand what you do.

NB! Replace bootloader filename with the one matching your SoC. Full list is here.

mw.b 0x42000000 ff 1000000
tftp 0x42000000 u-boot-hi3516xxxxx-beta.bin
sf probe 0
sf erase 0x0 0x50000
sf write 0x42000000 0x0 ${filesize}
reset

Uboot without tftp command

setenv uk 'mw.b 0x42000000 ff 1000000; setenv bootfile uImage.${soc} && tftpboot && sf probe 0; sf erase 0x50000 0x200000; sf write 0x40080000 0x50000 ${filesize}'
setenv ur 'mw.b 0x42000000 ff 1000000; setenv bootfile rootfs.squashfs.${soc} && tftpboot && sf probe 0; sf erase 0x250000 0x500000; sf write 0x40080000 0x250000 ${filesize}'

backup device

setenv ipaddr 192.168.1.10
setenv serverip 192.168.1.254    # Your TFTP server IP address.

sf read 0x42000000 0x0 0x800000
tftpput 0x42000000 0x800000 backup.img

restore device

if something goes wrong uboot can be bricked!

setenv bootfile backup.img
tftpboot
sf probe 0
sf erase 0x0000 0x800000
sf write 0x40080000 0x0 ${filesize}
reset
