Upgrading firmware
|
|
------------------
|
|
|
|
### Upgrading from GitHub
|
|
For old firmware running `sysupgrade` without parameters is enough. For newer firmware, run `sysupgrade -k -r` to update both kernel and rootfs.
|
|
|
|
__ATTENTION! Upgrading firmware can lead to "bricking" your camera. Make sure you are prepared both morally and skillwise. Have your rescue SD card and/or UART adapter ready. Be prepared to de-solder and reprogram flash chip as the last resort. Do not upgrade production cameras unless you really have to!__
|

|
|
### Upgrading from a TFTP server
|
|
|
|
[Set up a TFTP server](installation-tftpd.md).
|
|
|
|
Go to <https://github.com/OpenIPC/firmware/releases/tag/latest> and download the latest firmware bundle for your SoC.
|
|
Extract content of the bundle into the root directory of your TFTP server.
|
|
|
|
On the camera run:
|
|
|
|
#### Github: From Linux
|
|
|
|
```bash
|
|
soc=$(fw_printenv -n soc)
|
|
serverip=$(fw_printenv -n serverip)
|
|
busybox tftp -r rootfs.squashfs.${soc} -g ${serverip}
|
|
busybox tftp -r uImage.${soc} -g ${serverip}
|
|
```
|
|
|
|
#### Github: Alternatively, from U-Boot
|
|
|
|
for 8MB image
|
|
|
|
```bash
|
|
tftp ${baseaddr} uImage.${soc}
|
|
sf probe 0; sf erase 0x50000 0x200000; sf write ${baseaddr} 0x50000 ${filesize}
|
|
|
|
tftp ${baseaddr} rootfs.squashfs.${soc}
|
|
sf probe 0; sf erase 0x250000 0x500000; sf write ${baseaddr} 0x250000 ${filesize}
|
|
```
|
|
|
|
for 16MB image
|
|
|
|
```bash
|
|
tftp ${baseaddr} uImage.${soc}
|
|
sf probe 0; sf erase 0x50000 0x200000; sf write ${baseaddr} 0x50000 ${filesize}
|
|
|
|
tftp ${baseaddr} rootfs.squashfs.${soc}
|
|
sf probe 0; sf erase 0x250000 0xA00000; sf write ${baseaddr} 0x250000 ${filesize}
|
|
```
|
|
|
|
### Upgrading from local files
|
|
|
|
Go to <https://github.com/OpenIPC/firmware/releases/tag/latest> and download the latest firmware bundle for your SoC.
|
|
Unpack the bundle and upload its content on camera using `scp`:
|
|
|
|
```bash
|
|
tar xvf <firmware.tgz>
|
|
scp uImage* rootfs* root@<yourcameraip>:/tmp/
|
|
```
|
|
|
|
On the camera run:
|
|
|
|
```bash
|
|
soc=$(fw_printenv -n soc)
|
|
sysupgrade --kernel=/tmp/uImage.${soc} --rootfs=/tmp/rootfs.squashfs.${soc} -z
|
|
```
|
|
|
|
### Upgrading from SD card
|
|
|
|
#### SD Card: From Linux
|
|
|
|
Go to <https://github.com/OpenIPC/firmware/releases/tag/latest> and download the latest firmware bundle for your SoC.
|
|
Insert an SD card into your desktop PC. Unpack the bundle and copy its content to the card:
|
|
|
|
```bash
|
|
tar xvf <firmware.tgz>
|
|
cp uImage* rootfs* /media/<username>/<card-id>/
|
|
```
|
|
|
|
Insert the SD card into your camera.
|
|
On the camera run:
|
|
|
|
```bash
|
|
soc=$(fw_printenv -n soc)
|
|
sysupgrade --kernel=/mnt/mmcblk0p1/uImage.${soc} --rootfs=/mnt/mmcblk0p1/rootfs.squashfs.${soc} --force_ver -z
|
|
```
|
|
|
|
#### SD Card: Alternatively, from U-Boot
|
|
|
|
for 8MB image
|
|
|
|
```bash
|
|
mw.b ${baseaddr} 0xff 0x200000
|
|
fatload mmc 0:1 ${baseaddr} uImage.${soc}
|
|
sf probe 0; sf erase 0x50000 0x200000; sf write ${baseaddr} 0x50000 ${filesize}
|
|
|
|
mw.b ${baseaddr} 0xff 0x500000
|
|
fatload mmc 0:1 ${baseaddr} rootfs.squashfs.${soc}
|
|
sf probe 0; sf erase 0x250000 0x500000; sf write ${baseaddr} 0x250000 ${filesize}
|
|
```
|
|
|
|
for 16MB image
|
|
|
|
```bash
|
|
mw.b ${baseaddr} 0xff 0x300000
|
|
fatload mmc 0:1 ${baseaddr} uImage.${soc}
|
|
sf probe 0; sf erase 0x50000 0x300000; sf write ${baseaddr} 0x50000 ${filesize}
|
|
|
|
mw.b ${baseaddr} 0xff 0x500000
|
|
fatload mmc 0:1 ${baseaddr} rootfs.squashfs.${soc}
|
|
sf probe 0; sf erase 0x350000 0xa00000; sf write ${baseaddr} 0x350000 ${filesize}
|
|
```
|
|
|
|
### Flashing U-Boot via ymodem
|
|
|
|
Clean 320K of RAM amd load bootloader file into it:
|
|
|
|
```bash
|
|
mw.b ${baseaddr} 0xff 0x50000
|
|
loady
|
|
```
|
|
|
|
> _(press "Ctrl-a" followed by ":", then type)_
|
|
|
|
```bash
|
|
exec !! sz --ymodem u-boot.bin
|
|
```
|
|
|
|
After the file if uploaded, write it into ROM:
|
|
|
|
```bash
|
|
sf probe 0
|
|
sf erase 0x0 0x50000
|
|
sf write ${baseaddr} 0x0 ${filesize}
|
|
```
|
|
|
|
### Troubleshooting
|
|
|
|
If you got this error:
|
|
|
|
```console
|
|
losetup: /tmp/rootfs.squashfs.${soc}: No such file or directory
|
|
Rootfs: Unable to get hostname, execution was interrupted...
|
|
```
|
|
|
|
then try to update only kernel first:
|
|
`sysupgrade -k`
|
|
|
|
If it doesn't help, use `--force` option:
|
|
`sysupgrade -r --force`
|
|
|
|
If you caught a glitch, retrieve the most recent version of the utility:
|
|
|
|
```bash
|
|
curl -k -L -o /usr/sbin/sysupgrade "https://raw.githubusercontent.com/OpenIPC/firmware/master/general/overlay/usr/sbin/sysupgrade"
|
|
```
