Functional Description
The memory booting procedure reads data from a memory type device. If a valid booting image is found
and successfully read from the external memory device, the code begins to execute.
The peripheral booting procedure downloads data from a host (commonly a PC) to the device device by
means of Ethernet, USB or UART links. The ROM Code uses a host-slave logical protocol for
synchronization. Upon successful UART, USB or Ethernet connection the host sends the image binary
contents. The peripheral booting procedure is described in detail in
.
If the memory or peripheral booting fails for all devices enumerated in the device list then the ROM Code
gets into a loop, waiting for the watchdog to reset the system.
