Bootloader
On the CP6940 Ethernet Switch, the bootloader 'u-boot' (universal bootloader) is used. The bootloader initializ-es the
main components of the system like Unit Computer, DDR3 RAM, serial lines etc. for operation and per-forms a power on
self test (POST). After these steps have been finished, the bootloader loads and starts the linux OS stored on eMMC
device.
Two instances of the bootloader stored on the system. One resides on eMMC and is the one used for normal operation. In
case of failure or corruption of the normal operation bootloader, the failsafe bootloader that is stored on write protected
SPI flash will start instead. This redundancy concept allows for recovery actions in case of failure.
