1 Introduction

This document continues where the Zoom OMAP35x Development Kit QuickStart Guide concluded. The purpose of this document is to present information that may be useful after you’ve unpacked your kit, run through the demo, and are ready to begin development work. This document also points you to other resources depending upon your specific development needs.

■ Zoom OMAP35x Development Kit

■ Host PC (this document was written assuming a Windows XP host PC)

■ SD card reader

■ SD card

■ Active Internet connection

■ Serial cable (included in development kit)

■ Terminal emulation program (e.g., Tera Term)

2 Formatting a Bootable SD Card

The OMAP35x processor supports booting from SD and several procedures in this document walk you through a process using a bootable SD card. This section describes how to format an SD card so the OMAP35x Development Kit will recognize it as a bootable device.

A requirement of the OMAP processor is that the SD card must be formatted without an extended partition to boot properly. The built-in Windows formatting tool is not always able to do this. It has been found that the HP USB Formatting Tool version 2.0.6 appears to be the best tool for formatting an SD card so it can be used to boot an OMAP35x device. (NOTE: If you are using Linux or have access to a Linux box, you can find instructions on

boot

on the Texas Instruments Embedded Processors Wiki.)

The most recent version of the tool available on HP's site doesn't seem to work as well as version

2.0.6. As such, the tool needs to be downloaded from any number of third-party websites. To find these websites, perform a Google search for: HP formatting tool 2.0.6. (NOTE: As with downloading anything from the Internet, use caution in what sites you visit and what you download. Logic PD has no association with any of these websites and makes no guarantees to their validity or the usability of downloads from their sites.)

1. After the HP USB formatting tool has been installed on your host PC, insert an SD card into your USB card reader and open the formatting tool. (IMPORT ANT: Remember that formatting an SD card will erase its entire contents; back-up the SD card’s contents before continuing or select a card that doesn’t contain vital information.)

2. Select the SD card device and FAT32 from the File System drop-down menu. Click Start.

3. You will receive a warning that the contents of the card will be erased. Assuming you have backed-up the contents of the SD card, click Yes.

4. When formatting completes, you will receive a confirmation screen with the new file system type and the space allocation on the card similar to the window shown below.

You are now ready to add LogicLoader files (see Section 3) or the NAND flash recovery files (see Section 4) to the SD card and boot from SD.

3 Update LogicLoader

This section will walk you through the process for updating the LogicLoader bootloader software on your OMAP35x SOM-LV.

3.1 Setup Tera Term

Tera Term is a terminal emulation program available as a free download from the Internet. Logic PD recommends the use of Tera Term over HyperTerminal as it appears to be a more stable program; the instructions in this document assume the use of Tera Term.

All Tera Term settings are controlled by an .ini file that you can modify as needed to make your time in Tera Term as efficient as possible. For example you can preset the port settings.

1. Start the Tera Term program

2. From the menu, select Setup > Serial port

3. Select the appropriate COM port for your workstation and then change the port settings to:

a. Baud rate: 115200 b. Data: 8 bit c. Parity: None d. Stop: 1 bit e. Flow control: None

4. Click OK

3.2 Connect the Kit to the Host PC

1. Use the serial cable included with your kit to connect the serial port on the baseboard to the appropriate port on your host PC.

2. Power on your kit and hold down the v key on the keyboard. Doing this will provide specific boot information in the LogicLoader output. For instance, in the image below you see that the image type is Elf and it booted from the NAND device. This is a helpful trick to use to determine if your development kit is booting from the onboard NAND flash or the SD card.

3. Take note of what LoLo Version number appears in this welcome prompt. This will help you know if you need to upgrade to a new version.

4. Power off your kit.

3.3 Download New Version of LogicLoader

1. Log into Logic PD’s download site

2. Click on the All Downloads link for the OMAP35x Zoom Development Kit.

3. Scroll down until you find the section header LogicLoader Bootloader/Monitor.

4. Click on the + icon next to LogicLoader for the OMAP35x SOM-LV link; this expands the list of all available LogicLoader versions. If the current version is newer than what is on your OMAP35x SOM-LV, you should update.

5. Click on the version number marked (current) and save the file to your host PC.

6. After the.zip file finishes downloading, extract all files of the folder to a location on your host PC that you can access later on.

Now that you have downloaded the latest version of LogicLoader to your computer, you can update LogicLoader on your development kit using a bootable SD card.

3.4 Update LogicLoader Using a Bootable SD card

1. Prepare a bootable SD card as described in Section 2.

2. Locate the LogicLoader files that you downloaded to your host PC (see Section 3.3).

3. Copy the MLO file from that folder to the SD card. IMPORTANT: This file must be the first

added to the SD card for the kit to boot properly.

4. Next, copy the lboot.elf file to the SD card.

5. Remove the SD card from your USB card reader and insert it into the SD card slot on your OMAP35x Development Kit.

6. Press the POWER ON/OFF button to power the kit on and you should see a screen similar to what is shown below. (Hint: You can hold down the v key on the keyboard during boot-up to verify the Boot Device is SDMMC indicating the kit booted from the SD card.)

Notice that the LoLo Version number now shows the version you downloaded from the Logic PD website. This is because you have booted from the SD card containing that version.

7. Because LogicLoader resides in NAND, it is necessary to erase the old LogicLoader on the OMAP35x SOM-LV before updating. Type erase /dev/nand0 B0 B2048 Enter key.

and press the

8. Type update and press the Enter key.

9. LogicLoader is waiting for you to send the new version over the serial port. From the menu, select File > Send file to send the new LogicLoader version to your OMAP35x SOM-LV.

10. Navigate to the location where you extracted the LogicLoader files and select the file that includes nolo_lolo_NAND.upd. This file contains both NoLo and LoLo components necessary for updating LogicLoader. If you do not see a file that includes nolo_lolo_NAND.upd, please refer to the Release_Notes.txt included in the LogicLoader version download for special instructions.

11. Verify that the Binary checkbox is checked. Click Open.

12. Tera Term will begin sending the file to the OMAP35x SOM-LV.

13. Verify that the download was successful by waiting for an update done message to appear.

14. Remove the SD card from your development kit and press the RESET button on the baseboard.

15. If the new version number is displayed, you now have the updated version of LogicLoader installed on your OMAP35x SOM-LV.

4 Recover Corrupt Boot NAND Flash

This section describes how to recover corrupt boot NAND flash on the OMAP35x Development Kit by using a bootable SD card.

4.1 Recovery via SD Card Procedure

1. Prepare a bootable SD card as described in Section 2.

2. Log into Logic PD’s

download site using your username and password.

3. Click on the All Downloads link for the OMAP35x Zoom Development Kit.

4. Scroll down until you find the section header LogicLoader Bootloader/Monitor.

5. Click on the NAND Flash Recovery for OMAP35x SOM-LV link and save the ZIP file to your host PC.

6. Extract all the files contained in the ZIP file; then copy the MLO file from that folder to the SD card. IMPORTANT: This file must be the first added to the SD card for the kit to boot

properly.

7. Next, copy the remaining files to the SD card.

8. Eject the SD card from the host PC.

9. Power off the development kit and insert the SD card into the SD card socket on the development kit.

10. Power on the development kit.

11. The development kit shows an image on the 4.3” LCD display while the NAND flash is being reprogrammed.

12. When the process completes, the LCD display shows an updated image that indicates the process is complete.

13. Remove the SD card from the development kit and press the RESET button on the baseboard.

14. Your development kit should now boot from onboard NAND into the latest LogicLoader.

15. If the process fails, copy the entire Tera Term serial output and email the text to technical support using our
