Chapter 5. Installation and Testing
Using RedBoot with ARM Bootloader
RedBoot can coexist with ARM tools in flash on the IQ80310 board. In this configuration, the ARM bootloader
will occupy the flash boot sector while RedBoot is located at flash address 0x40000. The sixteen position rotary
switch is used to tell the ARM bootloader to jump to the RedBoot image located at address 0x40000. RedBoot is
selected by switch position 0 or 1. Other switch positions are used by the ARM firmware and RedBoot will not be
started.
Special RedBoot Commands
A special RedBoot command, diag, is used to access a set of hardware diagnostics provided by the board manu-
facturer. To access the diagnostic menu, enter diag at the RedBoot prompt:
RedBoot> diag
