DS90UB925EVB

Hi Rudi,

The drivers are typically found in the following directory: C:\Program Files\National Semiconductor Corp\Analog LaunchPAD v1.29.0010\Drivers

See the ALP installation guide in the DS90UH928QEVM evaluation board User's Guide: http://www.ti.com/tool/ds90uh928qevm

Are you using Windows 7? If so, Windows XP emulation mode is required, as described in attached document.1754.ALP_on_Windows7.pdf

Hi Ryan,

many thanks for your infos.

 I use Windows XP. The installation procedure of the DS90UH928QEVM is in principle the same as for the DS90UB925/926EVB, and I follwed.

Maybe you can mention a link where I can download the required driver.

best regards

Rudi

Hi Rudi,

The driver files for the ALP hardware should be in the directory C:\Program Files\National Semiconductor Corp\Analog LaunchPAD v1.29.0010\Drivers if you used the default installation directory.

If that doesn't work, consider downloading the latest ALP installation package from ti.com at: http://www.ti.com/tool/alp

Hi Ryan,

i tried to remove the ALP-SW and the USB-driver from the pc, download and proceed as described, without success.

The next was, to install the ALP SW on an other laptop, the result was the same. I can install the driver for the DS90UB926EVB, but not for the DS90UB925EVB.

What I have seen, if I install the DS90UB926EVB USB driver, the pc detects as a new USB device a NSC-USB-NANO....and starts installation from the desired path. in case of the DS90UB925EVB a AT90USB128DFU is detected and no driver is found....(can not install hardware)

Would it be possible for you to send me the USB driver ? Or could it be that the board is damaged or not flashed ?

Pls inform me.

best regards

Rudi

Hi Rudi,

It sounds like your DS90UB925 board is not flashed. Can you send me an email at ryan (dot) bailey (at) ti (dot) com ?

I can send you the hex file and instructions for re-flashing the controller. No programmers or anything special required - just the USB interface you're already using.

Ryan,

I have the exact same problem with a board I just received.  Could you point me to instructions for re-flashing the Atmel uC.

Thanks,

Rob James

To reprogram the Atmel uC on DS90Ux925 EVM, do the following:

1) Power up board

2) Place the controller into DFU mode: Press and hold SW1 -> Short JP3 and hold SW1 -> Wait 5 seconds -> Release SW2 -> Release (open) JP3

3) Connect USB cable to at J3

4) Launch Atmel FLIP software – downloadable at http://www.atmel.com/tools/FLIP.aspx

5) From menu bar: Device -> Select

6) Select AT90USB1287. Click OK.

7) From menu bar: File -> Load Hex File

8) Navigate to spa_eom.hex (typically located at “C:\Program Files\National Semiconductor Corp\Analog LaunchPAD\vx.x.x\Drivers”) and click Open

9) From menu bar: Settings -> Communication->USB. Click ‘Open’. 

10) From “Operations Flow” pane, select all checkboxes

11) On “Operations Flow” pane, click Run

12) Wait for device programming process to complete

13) Click “Start Application” Button. Ensure ‘Reset’ box is checked.

14) Disconnect USB Cable

15) Power down board

16) Power up board

17) Plug in USB Cable

18) Close Atmel FLIP software

Hi Ryan, seems like you know how to get these DS90UB925EVBs up and running.  I'm using the USP-mini port now after a long frustration session with the I2C port, and a Aardvark I2C host adapter.  The i2C method didn't work, so now I loaded the Atmel nano usb drivers, and windows 7 seemed to be happy, but when I ran Analog Launch Pad, it crashed and said: MainGUE.exe stopped working.  A problem caused the program to stop working correctly.  Windows will close the program and notify you of a solution is available.  close program"

I'm trying to talk to the board via ALP so I can change some register settings and put the I2C in by pass mode etc.

I loaded ALP twice now and it's still not working.  Got any ideas?

Regards,

Greg

Hi Greg,

Are there any entries in MainGUI.exe.log or MainGUI.log log files? Run ALP as administrator.
