STx provides 3 Levels of Support:
An issue has been discovered with the ADS512101 connections to the DDR MVTT and MVREF pins. They are both connected to the same 0,9volt rail. They should be powered separately. See the ADS512101 Rev 4 Errata dated 9/16/2009 or later for a solution.
Before contacting ADS512101@silicontkx.com for support, try this Ehternet test. On a PC Linux server:
Identify IP address xxx.xxx.xxx.yyy
Identify gateway IP address xxx.xxx.xxx.zzz
Identify a free IP address xxx.xxx.xxx.xxx
At u-boot prompt set the IP address of teh ADS512101 to the free address:
set ipaddr xxx.xxx.xxx.xxx
Set the gateway and server IP addresses:
set gatewayip xxx.xxx.xxx.zzz
set serverip xxx.xxx.xxx.yyy
set netmask 255.255.255.0
If the ping is successful at u-boot prompt the hardware is OK.
If you can ping in u-boot but cannot ping in (LTIB) Linux, see patch: linux-18.104.22.168-mpc5121-122-FEC-fix-fec-DMA_CONTROL-field-o.patch on www.bitshrine.org/gpp.
A work around (without this patch) is to ping first in u-boot before booting to (LTIB) Linux
Yes, MPlus5121 features the ADS512101 mainboard in a small Mini-ITX case. The system includes a hard drive, Micro-SD card, XGA 8.4 inch LCD and integrated power supply. Freescale's Linux OS is included.
The product is the same. The ADS512101 includes a development kit.
For the current Rev 3 ADS512101, the MPC5121e is not in a socket.
At this time, PATA does not function on the ADS512101. It will be functioning on the Revision 4 board due in July 2008. If you need PATA on your current ADS512101, Contact STx for upgrades or return authorization.
The SD is a micro (uSD) which is mechanically smaller but electrically identical.†When you buy a micro-SD card, you get an SD card carrier to insert it into SD slots when needed. Drivers for the micro-SD will be available soon from STx.
The current MPC5121e revision is 1.5 for the Rev 3, ADS512101.
If the board does not appear to be on (LEDs not lighting), hold the power button down for 5 seconds. Release. Then press power button again. If this does not solve the problem, please Contact STx for a possible CPLD update.

Some ADS512101 boards with LTIB preloaded operate in two video modes.† A command has been patched in Freescale's LTIB that will enable either mode of operation.† This command changes the number of color bits that drive each of the video output modes. Default enables the DVI (J6) output for correct color information.† In the default mode both the LVDS (P20) and TFT (P21) will not output correct color information.
To enable both the LVDS video out (P20) and TFT video out (P21) a command has to be executed at the Linux prompt as follows: gamma_set LCD
To switch back to DVI video output, execute at the Linux prompt: gamma_set
If the color outputs in your ADS512101 does not change with this command, current LTIB Changes and patches are in the STx Downloads.
Yes, the ADS512101 supports wireless connectivity via a mini-PCI radio. You must choose a radio board and transmitter for this.
The MPC5121e SATA function has errata. This is expected to be correct on Freescale's next release and will be available in the ADS512101 Rev 4 product due in July 2008.
U-Boot puts the registers in a known state at power-up. The only write that u-boot does for the DVI controller is at address 0x38 -- it initializes reg 0x8 to value 0xbf. This puts it in normal operating mode from reset.
CAN does work but it is slow due to low supply rail, 3.3V. This can be corrected by routing the CAN Vdd pin of xcvr. Lift the Vcc pin of 3.3 and connect a wire from the CAN xcvr to a 5volt supply pin.
ODT is a chip option and only needed for high speed DRAM (like 800 or 1066 MHz) which is not used with the MPC5121.
The DVI controller needs to be brought out of reset after power on.† This is accomplished by placing a 32 AWG mod wire between R232ís right pad and R32ís right pad.
This may be due to an over driving of the VGA output. The resistors R224, R226, R229 must be halved in value (37.5 ohms).
An issue with U2, 3.3v regulator, was discovered during memory intensive operations that may result in erratic behavior such as restarts or the CPU freezing. Corrective action requires the addition of a wire and and the latest CPLD code. Contact ADS512101@silicontkx.com or 800.827.2650 x182 for an RMA or more details on field repairs.
A potential issue with the ground stability on PIN 5 of P8. If you can check the voltage and it is NOT 0volts (it may be as high as 0.8volts), you will have to connect a strap to a better ground. We suggest strapping it to Pin 2 of P6.
The ADS512101 has been produced in three PCB mask colors. The original was a standard brown. In 2008 the color was changed to red for marketing reasons. In 2009 it was changed to light beige (off white) for quality control purposes. Mask color does NOT affect performance.
Lead-time for the ADS512101 product is stock to 4 weeks.
We provide many ruggedization services. Industrial temperature (-40 to +85 C) ADS512101s are build-to-order. For an industrial temperature request, and to know more about thermal cycle/burn-ins, shock/vibration, coating/humidity services, Contact STx.
This is a Level 2 STx Technical Support request. Please Contact STx for information about STx Support Services.
The ADS512101 U-BOOT has limited drivers for booting the board. These include onboard memory, serial I2C, Ethernet, and PCI. In the future U-Boot will include a low level USB Driver for mass storage booting and a diagnostic tool.
All other Drivers are provided by an Operating System Environment.
The ADS512101 only supports U-BOOT for a loader.
Yes, a license-free self-hosted version of Linux, provided by Freescale, is preinstalled on the ADS512101 called Linux Target Image Builder, LTIB.
Freescale's LTIB, is preloaded on the ADS512101, but always check the Freescale site for the most recent revision. LTIB includes several drivers. See the Freescale ADS512101 LTIB website for a complete list of supported peripherals.
Freescale's LinuxBSP is provided free and is 'AS IS' software. Freescale nor Silicon Turnkey Express provide free support.

A working copy of U-Boot will allow you to flash images. Please refer to the U-Boot Manual located at www.DENX.de.
If the Main Flash U-Boot image is corrupt restore U-Boot from the Backup Flash. Please refer to the ADS512101 Quick Start Guide or Section 7.3 of the ADS512101 Userís Manual.
If both U-Boot and Backup Flash are corrupt, STx can recommend using the Abatron BDI3000 JTAG Debugger for troubleshooting. STx uses this product internally to develop its boards. You can purchase the Abatron BDI3000 (BDI2000 for CodeWarrior) from STx directly.
Please refer to Section 3.2 of the ADS512101 Userís Manual.
Verify that the P4 jumper for backup flash is removed. If you re-installed u-boot the MAC address may have to entered. See instructions to locate and reinstall the MAC address in either the Quick Start Guide or User Manual.
STx has added several patches for LTIB. Freescale will release a new revision late in May 08 with these and other patches included. See our download site for LTIB Changes.

The Networking information may have to be set in the environment. You may need to set the following at the prompt:
setenv gatewayip xxx.xxx.x.x, (the gateway address, such as 192.168.0.1)
setenv netmask xxx.xxx.xxx.x, (the network mask address, such as 255.255.255.0)
setenv ipaddr xxx.xxx.x.xx, (the ip address, such as 192.168.0.20)
If downloads from a server are expected, the server ip may need to be set:
setenv serverip xxx.xxx.x.xx, (the server ip address, such as 192.168.0.10)
