Normally camera boots from the internal NAND flash memory, and it is always possible to boot it from the micro SD card, so even corruption of files on the internal flash will not "brick" the system. There are no buttons or switches on the camera - it should be instructed to change the boot source. Always booting from micro SD is not practical - in that case it would not be possible to leave a non-bootable card (intended just for image/video storage) in the camera slot.

There are two ways to switch camera to the micro SD boot mode.

One requires camera to be connected to the host computer with the USB cable (micro USB socket under the network jack - marked "console" on the picture). There is an internal USB-to-serial converter in the camera (CP2103) that offers 4 additional GPIO signals in addition to just the serial connection. One of these signals selects the boot source (GPIO0 - 0 - MMC, 1 - NAND), another (GPIO3 - 0 reset, 1 - normal operation). Unfortunately GPIO control of the CP2103 is not in a mainline cp210x Linux driver so this functionality requires a modified version (see instructions below).

Another way to "tell" the camera to boot from the &mu;SD card instead of the internal NAND flash is to use a mechanically modified card or card adapter (such cards are provided with the camera). Standard specifies two alternative ways for detection of the card presence - one is a mechanical switch (closed when the card is inserted), another is a pull-up resistor on a data line. Camera uses both signals at boot time to determine the boot source:
* Switch not closed, pull-up resistor not detected -> no card present, boot from the internal NAND flash
* Switch closed -> data (non-bootable) card present, boot from the internal NAND flash
* Switch not closed, pull-up resistor is detected -> bootable card present, boot from the MMC card

==<font color="blue">Boot instructions</font>==
===Internal NAND flash (default)===
* Make sure the recovery card is not inserted
* Power on

===Recovery micro SD card===
Requirements:
* A modified card that doesn't lock the mechanical CD pin in the slot - it's done by carefully filing off the corner (see Fig.1) - most cards have circuitry there and get damaged. Use the one that came with the camera or order a new one.
Instructions:
* insert the card, power on

===Regular micro SD card===
Requirements:
* &mu;USB-to-USB cable
* Linux: compile [https://sourceforge.net/p/elphel/cp210x_gpio/ci/master/tree/ cp210x driver]
Instructions:
* Power on
* Connect the camera's console port (see Fig.2, right under the &mu;SD slot) to PC using &mu;USB-to-USB cable
{|
|[[File:NC393-CS marked ports.jpeg|thumb|200px|Fig.2 10393 camera ports]]
|}
* Reload the cp210x driver:
** unplug the &mu;USB-to-USB cable
** In the terminal from the directory where the driver was built, run:
sudo rmmod cp210x
sudo insmod cp210x.ko
** plug the cable back (the driver will stay loaded until the PC is rebooted).

* In the terminal from the directory where the driver was built, run:
./cp210x_gpio.py 0x6;
./cp210x_gpio.py 0xe;

* To reboot back to NAND flash w/o power cycling:
./cp210x_gpio.py 0x7;
./cp210x_gpio.py 0xf;

===Other boot options===
The instructions are defined by the 3 options above.
They define where the camera will load the u-boot, device tree and kernel from: &mu;SD card or NAND flash. The location of rootfs ("/") is set in the device tree. Available locations for rootfs:
* '''any &mu;SD card partition'''. The default device tree parameter is:
bootargs = "cma=336M console=ttyPS0,115200 root=/dev/mmcblk0p2 rw ip=192.168.0.9 earlyprintk rootwait rootfstype=ext4";
* '''any internal NAND flash partition'''. The default parameter is:
bootargs = "cma=336M console=ttyPS0,115200 root=ubi0:elphel393-rootfs rw ip=192.168.0.9 earlyprintk rootwait rootfstype=ubifs ubi.mtd=4,2048";
* '''any internal SSD''' (if installed) partition. There is no default device tree.
* '''RAM''' - unpack an archive from a &mu;SD card FAT32 partition into RAM but it was tested a while ago:
bootargs = "cma=336M console=ttyPS0,115200 root=/dev/ram rw ip=192.168.0.9 earlyprintk ramdisk_size=262144";

There are no buttons or switches on the camera and the camera should be instructed to change the boot source. Always booting from micro SD is not practical - in that case it would not be possible to leave a non-bootable card (intended just for image/video storage) in the camera slot.

Always booting from micro SD is not practical - in that case it would not be possible to leave a non-bootable card (intended just for image/video storage) in the camera slot. -There are two ways to switch camera to the micro SD boot mode. One requires camera to be connected to the host computer with the USB cable (micro USB socket under the network jack - marked "console" on the picture). There is an internal USB-to-serial converter in the camera (CP2103) that offers 4 additional GPIO signals in addition to just the serial connection. One of these signals selects the boot source (GPIO0 - 0 - MMC, 1 - NAND), another (GPIO3 - 0 reset, 1 - normal operation). Unfortunately GPIO control of the CP2103 is not in a mainline cp210x Linux driver so this functionality requires a mudified version (see instructions below).+There are two ways to switch camera to the micro SD boot mode.

Another way to "tell" the camera to boot from the &mu;SD card instead of the internal NAND flash is to use a mechanically modified card or card adapter (such cards are provided with the camera). Standard specifies two alternative ways for detection of the card presence - one is a mechanical switch (closed when the card is inserted), another is a pull-up resistor on a data line. Camera uses both signals at boot time to determine the boot source: Another way to "tell" the camera to boot from the &mu;SD card instead of the internal NAND flash is to use a mechanically modified card or card adapter (such cards are provided with the camera).
