The personality board connects to the Debug board using a 500-pin connector. The connector is keyed to avoid misconnection, so there is only one way to connect these boards. Then, connect the CPU board to the underside of Debug board. Certify the version of bootloader When updating the BSP files of a system, it's recommended to rewrite a right version of bootloader in the target. Connect platform to PC To connect the 3-Stack platform to your host PC: Connect one end of an RS-232 serial cable (included in the kit) to a serial port connector (CON4) on the Debug board and connect the other end to a COM port on the host PC. Configure SW4-1 to ON. Make sure that SW4-8 is ON, to supply power to all three boards. Configure SW4-2 to OFF. Confirm that the Bootstrap switches (SW5–SW10) are set for external NAND boot (see more here) Connect the regulated 5V power supply to the appropriate power adapter. Plug the power adapter into an electrical outlet and the 5V line connector into the J2 (5V POWER JACK) connector on the Debug board. Start a serial console application on your host PC with the following configuration: Baud Rate 115200 Data Bits 8 Parity None Stop Bits 1 Flow Control None On the Debug board, switch the power switch (S4) to 1. The OS image pre-loaded in the 3-Stack board will boot and the debug messages from the bootloader should now appear on the serial console application on your PC See Also For a setting without the Debug board see Demonstration Platform.

The latest i.MX28 BSP provided by Freescale (10.12) is based on a 2.6.35 kernel. If you want to use the latest and greatest kernel version from kernel.org, follow the steps below. 1. Get the mainline kernel: git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git(this is only done once) git checkout -b yourlocalbranch origin/master 2. Export the toolchain PATH=/opt/freescale/usr/local/gcc-4.4.4-glibc-2.11.1-multilib-1.0/arm-fsl-linux-gnueabi/bin/:$PATH export PATH export CROSS_COMPILE=arm-none-linux-gnueabi- export ARCH=arm 3. Build the kernel make mxs_defconfig make uImage sudo cp arch/arm/boot/uImage /tftpboot (In this example /tftpboot is the directory used to send files via TFTP) 4. Kernel command line: On U-boot change the following parameter of the kernel command line: console=ttyAM0,115200 to console=ttyAMA0,115200 5. On LTIB You can still use LTIB to provide the root file system. ./ltib -c Target System Configuration Options ----> Unselect [] boot up with tty and login If this option is selected the serial port will fail to open as it still uses ttyAM0 instead of ttyAMA0. 6. Boot the kernel via TFTP and mount the rootfs via NFS.

Most engineers should incorporate the following fundamental methodology when designing and bringing up a new board design: 1. Review the schematics and layout to ensure proper connectivity of all devices 2. Once the board returns from the manufacturer, measure and document all of the voltage rails of each IC on the board (especially the SoC and DRAM) 3. Ensure JTAG debugger connectivity (due to the complexity of systems today, every new board design should have some “hooks” to allow JTAG connectivity, even if these are simply test points) 4. Bring up and ensure proper DRAM functionality; it is imperative the first three steps are precisely accomplished – often times, DRAM instability or non functionality is due to improper connection (including not being connected to the voltage net) or poor layout. Once these four steps are completed, the board can then proceed to a more broad based checkout of other peripherals using some type of compiled test code executed from DRAM. More often than not, the end user’s board will differ from Freescale reference design boards either in how the DRAMs are connected or simply by using a different DRAM vendor.  As such, tools were created to aid in the development of DRAM initialization scripts.  The resulting script, though targeted for the RealView development system (aka include files), can be easily ported to another debugger’s command syntax or to assembly code for use in boot loaders.  These tools are Excel spread sheet based and include a “How To Use” tab, making the tool usage relatively self-explanatory.  Each tool is unique to a specific i.MX processor and to the DRAM technology used with each processor.  This attached files are tools available for the following i.MX SoCs:

Debugging with JTAG JTAG was created to test populated circuit boards after manufacture. Nowadays, JTAG is primarilly used to access sub-blocks of integrated circuits and useful mechanism for debugging embedded systems. When used as a debugging tool, an in-circuit emulator - which in turn uses JTAG as the transport mechanism - enables a programmer to access an on-chip debug module which is integrated into the CPU, via the JTAG interface. The debug module enables the programmer to debug the software of an embedded system. Besides debugging, the second purpose of the JTAG interface is allowing device programmer hardware to transfer data into internal non-volatile device memory. Some device programmers serve a double purpose for programming as well as debugging the device.
