Boot:

← Older revision Revision as of 02:19, 30 November 2016 Line 26: Line 26: 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 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.

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.

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 μSD 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 μSD card instead of the internal NAND flash is to use a mechanically modified card or card adapter (such cards are provided with the camera).
