Mohamed, I formatted the drive using ip_address/format_disk.php. This created sda1 > and raw sda2.

2 partitions are used for 'fast recording'. Not having a file system on sda2 partition saves some time to perform writes, and also should reduce the wearing out of SSD. And ext4 sda1 partition is intended to store information where to start/continue recording from (camogm.disk). You don't have to use it if normal recording works. In this case you can have only a single partition - use fdisk to repartition. But if you increase the image quality normal recording might be too slow - you can test this - in camogm gui click on the 'show buffers' and run recording.

Though it's possible to implement but will probably slow down recording. You can separate them on your PC. split_mov.php which I mentioned before - does splitting and naming files as <timstamp>_<port>.<ext> Then they can be combined back to movs with ffmpeg, for example. For image format, COLOR is set as 0.

I didn't include the device tree for nand for 14MPx. Now it's here(devicetree.dtb) <https://community.elphel.com/files/393/20180406/nand/mt9f002/>.
