|
|
|
Please look up your sensor in [the list of supported devices][1].
|

|
|
### Initial device firmware updates
|
|
|
|
```
|
|
setenv bootargs 'mem=${osmem:-32M} console=ttyAMA0,115200 panic=20 root=/dev/mtdblock3 rootfstype=squashfs init=/init mtdparts=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 gk7xxxxxxx # Set your SoC. gk7202v300, gk7205v200, or gk7205v300.
|
|
setenv osmem 32M
|
|
setenv totalmem 64M # 64M for gk7202v300, gk7205v200, 128M for gk7205v300.
|
|
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
|
|
```
|
|
|
|
### A trick for GK7205V300+IMX335 users
|
|
|
|
```
|
|
echo -e "!/bin/sh\n\ndevmem 0x120100f0 32 0x19\n" >/etc/init.d/S96trick
|
|
chmod +x /etc/init.d/S96trick
|
|
```
|
|
|
|

|
|
|
|
### 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](https://github.com/OpenIPC/firmware/releases/tag/latest).
