Solutions
What is an Embedded System?
• Small device that can be “embedded” into
another device or enclosure
• Often does not have a direct user interaction
• Low power consumption
• Usually has a low cost
• Combine common HW components such as:
– Microprocessor
– Memory (SDRAM and Flash)
– I/O peripherals (UART, USB, GPIO, etc.)
• Pre-integrated software support
• Development Kit with Software Tools
• Add-on Application Kits
Page 7
Why it is different from a “Box”?
• It needs more things than a “box” does:
– design a carrier/support board
– stabilized power supply
– connectors, level shifters, etc.
– might need an enclosure
• But it is better because:
– has a much lower cost
– more suitable for very high volume (1K30K)
– easier to customize/expand

Digi Bootloader: U-Boot
• What does a bootloader do?
–
–
–
–
–
–
–
Initialize hardware
(optional) Splash screen image support
Uncompress data/code from FLASH to memory
Establish basic networking functionalities
Start OS (WinCE, Linux, NET+OS)
Allow firmware updates – erase and program FLASH
Customization of settings
• Das U-Boot is an open-source, cross-platform bootloader
that support many embedded boards and CPUs
• Allows extensions for easy tailoring
• Digi bootloader is based on U-Boot-1.5.x
• NOTE: U-Boot does not support IPv6 and there is no
plan to add it for now

BusyBox
• Once Digi DEL has booted fully, the BusyBox will
show up
• BusyBox combines tiny versions of many common
Linux utilities into a single small executable
• The commands included are rebuilt specifically for
small and embedded system (size and resources
optimized)
• It is also modular so users can easily include or
exclude commands (or features)
• It is basically a “Bourne shell on a diet”!!!
• NOTE: Our pre-built binary has IPv6 support
DISABLED Customers wanting to use IPv6 on
busybox need to enable and rebuild busybox
