The Sigmastar IPL (pre-bootloader) allows to boot a custom U-Boot from the sdcard. With this temporary OpenIPC firmware you can create a backup of the nand and flash the permanent firmware afterwards.
- Connect your sdcard to your computer, create a 1 GB partition and format it as FAT32 / VFAT.
- Download ssc338q-initramfs.zip
- Copy all files to the root directory of the sdcard, update your wireless credentials on autostart.sh:
#!/bin/sh
+WLAN_SSID="Router"
+WLAN_PASS="12345678"
- Put the sdcard into the camera module, start it and wait until it connects to your router.
- Use ssh to connect to the camera:
ssh [email protected]
12345
- /dev/mtd0 uses the complete partition size of the nand flash.
- This might take some time, the backup to the sdcard is rather slow.
nanddump -f /mnt/mmcblk0p1/backup-nand.bin /dev/mtd0
- Alternatively the flash content can be uploaded via tftp.
cd /dev
tftp 192.168.1.10 -pr mtd0
flash_eraseall /dev/mtd0
nandwrite -k /dev/mtd0 /mnt/mmcblk0p1/ssc338q-fpv.bin
rm /mnt/mmcblk0p1/UBOOT
reboot -f
