The Arm Industrial Module AIM 711 comes with RedBoot installed as the default boot loader.
For developing without having a finished custom board, a starter-kit with a minimally configured board is available. It offers all the connectors needed for development, including serial device, Ethernet, power supply and an extra connector for the external bus.
A 6V - 7.5V power supply must be connected to J2 or TB1. At J2 the inner pin is V+ and at TB1 it is pin 1.
The AIM 711 has 3 serial devices, which are the debug and diagnostic channel COM0 (/dev/ser0), the high performance 16550 UART COM1 (/dev/ser1) and the second internal device COM2 (/dev/ser2).
To use the debug channel, which is also the default for RedBoot, the supplied DB9-male cable must be connected to CN4. If the also available service board is used, the above connector must be disabled by setting JP1.
COM1 is available over the RJ45 connector CN2. This device can be configured as a RS232, RS422, RS485 or TTL level
COM2 is only available with TTL level at CN5.
The RJ45 connector CN1 is for Ethernet.
In order that Redboot can overwrite itself, Redboot is built as a ROMRAM image.
Load the RedBoot binary to the next free space:

To rewrite the FLASH using JTAG the service board must be used, which includes a JTAG connector.
