5 This file documents the Buildroot support for the Freescale i.MX31 PDK in "3
8 The i.MX31 Product Development Kit (or PDK) is Freescale development board [1]
9 based on the i.MX31 application processor [2].
11 For more details on the i.MX31 PDK board, refer to the User's Guide [3].
16 First, configure Buildroot for your i.MX31 PDK board:
18 make freescale_imx31_3stack_defconfig
24 You will find in ./output/images/ the following files:
30 The generated zImage does include the rootfs.
35 The i.MX31 PDK contains a RedBoot bootloader in flash, which can be used to
36 boot the newly created Buildroot images from the network.
38 This necessitates to setup a TFTP server first. This setup is explained for
39 example in Freescale i.MX31 PDK 1.5 Linux User's Guide [4].
41 Here is a sample RedBoot configuration, for proper network boot of Buildroot on
45 Run script at boot: true
47 .. load -r -b 0x100000 zImage
48 .. exec -c "console=ttymxc0,115200"
50 Boot script timeout (1000ms resolution): 2
51 Use BOOTP for network configuration: false
52 Gateway IP address: <your gateway IP address>
53 Local IP address: <your PDK IP address>
54 Local IP address mask: 255.255.255.0
55 Default server IP address: <your TFTP server IP address>
57 Console baud rate: 115200
58 Set eth0 network hardware address [MAC]: false
59 GDB connection port: 9000
60 Force console for special debug messages: false
61 Network debug at boot time: false
63 Adapt those settings to your network configuration by replacing the appropriate
64 network addresses where necessary.
66 You might want to verify that your i.MX31 PDK switches settings are the correct
67 ones for UART, power, boot mode, etc. Here is a reference switches
72 ON off off off off off off ON
74 SW5 SW6 SW7 SW8 SW9 SW10
77 See the i.MX31 PDK Linux Quick Start Guide [5] for more details on the switches
80 Connect a serial terminal set to 115200n8 and power on the i.MX31 PDK board.
81 Buildroot will present a login prompt on the serial port.
