### SSC338Q + IMX415 + NAND flash, board from CamHi vendor
#### Quick note on experiments, will be revised and updated

#### Summary
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.

#### Prepare
- Connect your sdcard to your computer, create a 1 GB partition and format it as FAT32 / VFAT.
- [Download ssc338q-initramfs.zip][1]
- Copy all files to the root directory of the sdcard, update your wireless credentials on autostart.sh:
```diff
#!/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 root@192.168.1.100
12345
```

#### Backup 
- /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
```

#### Install
```
flash_eraseall /dev/mtd0
nandwrite -k /dev/mtd0 /mnt/mmcblk0p1/ssc338q-fpv.bin
rm /mnt/mmcblk0p1/UBOOT
reboot -f
```
