ConnectCore 9P 9360/9750
On the ConnectCore 9P 9360 and ConnectCore 9P 9750 modules, the SPI boot loader is
loaded from the SPI EEPROM which initializes the RAM. Then additional code (~1kB) is
loaded into RAM (address 0x0). This code loads U-Boot from NAND flash and executes
it.
In the next step, U-Boot configures the serial console, the Ethernet interface and the Flash
memory and loads the settings stored as environment variables in the nonvolatile memory.
Then, it waits some seconds (programmable) before it loads and starts the operating
system image. You can stop the auto-boot process by sending a character to the serial port
(pressing a key on the serial console connected to the target). If stopped, U-Boot displays
a command line console similar to this:
