5. FIRMWARE DESIGN SPECIFICATION
The device uses a generic Linux system, version 3.14.38. ARM tool chain is supplied to
compile and debug customer/user applications.
A preinstalled Core/Base Application is launched by OS at startup.
5.1 Secure boot
Below is the Boot process of the system:
Power On
The boot process begins at Power On Reset (POR) where the hardware reset
logic forces the ARM core to begin execution starting from the on-chip boot
ROM.
Boot ROM process
Boot ROM will authenticate the u-boot, and pass control to u-boot.
U-boot process
U-boot verifies the OS image, and pass control to OS.
OS process
OS starts the Core/Base daemon, and user applications.
5.2 Keys
Several security keys are used in the device, as follows. (The keys are generated by PKI tree.
All certificates are X509 format.)
CA key: This is the topmost key and is only used for signing SRK certificates.
SRK key: Super Root Key is a component of the PKI tree. SRK is an RSA key pair
which forms the start of the boot-time authentication chain. The hash of the SRK public
key is embedded in the processor using OTP hardware. SRK private key is held by the
CA.
Page 11 of 18
CSF key: This key is a subordinate key of the SRK key, and is used to verify the CSF
data. CSF (Command Sequence File) is a binary data structure interpreted by the HAB
to guide authentication operations.
IMG key: This key is a subordinate key of the SRK key, and is used to verify the u-boot
image.
OSK key: This key is a subordinate key of the SRK key, and used to verify the OS
image and the monitor daemon.
APK key: This key is a subordinate key of the SRK key, and used to verify applications.
5.3 Core/Base Application
Core/Base application is used to update the OS and/or add/update/remove application(s)
through Ethernet.
Interface: Ethernet, port 14000.
Command & response format
Command format:
02 + length (little endian, 4 bytes. Includes ALL from 02 to 03) +
command (1 byte) + data + CRC (2 bytes) + 03
Note: The maximum length of a command should be less than 1200 bytes.
Response format:
02 + length (little endian, 4 bytes. Includes ALL from 02 to 03) +
Error-status (1 byte) + [data] + CRC (2 bytes) + 03
Error status codes:
0xE0: No error
0xE1: The command is invalid
0xE2: The command is error formatted.
0xE3: The file cannot be deleted.
0xE4: The file’s mode cannot be obtained.
0xE5: The file’s mode cannot be changed.
0xE6: The file cannot be created.
