ADS1248EVM-PDK installation problem

Hello,

I have the same problem with installaton ADS1248EMV-PDK.

Additionaly , when I power on PDK i cam see on LCD following text:

1.BRD TST

 tehn I pressing UP

2. LCD TEST - all chars are displayed

3. next I pressing UP , and i can see PRESSUP

4. naxt I pressing UP and i can see "arrow up"

5 next I press OK button  - on LCD I can see DAC and next 2.5V and green LED is lighting

6. next I press OK button - on  LCD I can see 4.5V

7. next I press OK  -On LCD is NODEV

8. next I press UP arrow - I can see 96 and next HDR 0H

9 next I press UP arrow - on LCD is FAIL

All Jumpers are configured as Figure 3 on page 8.

Is anybody from Texas Instruments can hepl me  ?

One possibility is that the hardware is trying to use a COM port higher than 20.  We have seen issues when Windows assigns the device to >COM20. We don’t fully understand the reason, but this seems to be an issue.  You can manually reassign the port to a lower free COM port (say less than COM10) in the Device Manager.

Let me know if this works.

If it doesn’t send me a screen shot of the C:\Program Files\Texas Instruments\TI3410XP\ directory with the file dates and sizes. There might be a problem with the loading of the TUSB3410 driver.

Hugo -

As of today, a new version of the plug-in is available, v1.1.0 for the ADS124xEVMs.  Please use the update feature to download and install the latest software or download it from the product page.

This software should clear up some of the connection issues that have presented in the past. It also contains the latest version of the TUSB drivers that Joe mentioned.

Please let us know if you continue to have problems.

I set COM2, maybe something is wrong with software (it is small)

I reinstalled software and installed  new update ads1248evm-pdk-plugin-1.1.0.exe  unfortunately it is not working.

I have to choose manualy COM 2 and it starting scanning , It finding device but don't want to update 

AndrzejS -

Did you allow the new TUSB3410 drivers to install?  It doesn't look like the have been installed.

In the Device Manager, the item "USB-Serial Port (COM2)" should show up as TUSB3410 Device (COM2).  These drivers should be included in the new installation exe and will start automatically when the plug-in is finished installing.  You should get a prompt saying "Where previous drivers installed.."  This is the beginning of the TUSB3410 drivers.

Greg

Hello,

I update the T3410 driver by the new plugin but i still have the problem. The COM number is 4 since the beginning , I try another number (<10) but it doesn't solve the problem.

With the old EVM plugin I had the "C:/program files/Texas Instrument/" folder (I had the same files with same size as AndrzejS.) but with the new one I don't have it so I can't do a screenshot of it.

Have you another solution ?

Hugo -

So the files you are looking for were probably associated with the old driver, which are no longer present.

Can you verify that the ADS1248EVM has the jumpers/switches configured in the settings shown in Figure 7 of the ADS1248EVM User Guide?  Different settings from this figure may not work with this software although the hardware will still work correctly.

Additionally, when you restart the software and hardware, is the port recognized and just not programming or is the port not found?  When you get the error, can you capture/send the "fw_load.log" file that is located in the ADCPro installation directory under "saved"  (default will be C:\Program Files\ADCPro\saved\)?

Regards,

Greg

Hi,

I was trying install softwate on another computer, bud effect is the same.

I couldn't run with new software (ads1248evm-pdk-plugin-1.1.0.exe) - driver not found, so I decided install software TUSB3410 (swrc094e.zip).

I think softwaere was installed correct - screenshots, bud software doesn't work correct.

I have to manually choose COM, and after this ( switch in correct position - BSL, Jumpers on ADS1248 - figure 3 document sbau142a.pdf ) is still problem.

I don know why.

Can anybody from TI help me , wrte veri easy what I sholul to do , step by ste, point after piont

Greg , you are writting " ...Can you verify that the ADS1248EVM has the jumpers/switches configured in the settings shown in Figure 7 of the ADS1248EVM User Guide?..."

hello,

the ads1248evm is configure like the figure 7 user guide so i don't think it's the matter. When I restart software and hardware the port is recognized and programming failed.

That what there is in the "fw_load.log" file :

Start FW load sequence....

Starting download

Start FW load sequence....

Starting download

Start FW load sequence....

Starting download

Hello,

I have tried on 4 (four)  computers, on each is the same.

I think problem is in software.

I hope engeeners from TI fin solution.

I'm sending communication between MMB3 and computers - two times 

Hugo and Andrezej -

A couple more questions to rule out a couple of items:

1. Is the only connection you have to the MMB3 and ADS1248EVM from the computer (via USB)?  You should have no additional power supplies/adapters connect.

2. When you first power up the MMB3 board, do you both see a sequence of messages?  ie "RESET", "SELFCAL", "BRD TEST" or other?  Can you describe them?

3. Can you verify that the small red DIP switch (SW4) on the MMB0 is closing?  It should measure open with switch to OFF (to the right) and a short with the switch to BSL (to the left).

Regards,

Greg

Hugo and Andrezej,

Let's go back to the initial problems and discuss the process.  First I would like to add a little background.  The MMB3 motherboard is used for a number of different EVMs.  The MMB3 has some test firmware installed initially to verify that the motherboard will download software via USB, as well as verify some basic functions of the motherboard.  There are a number of features on the motherboard that are not used for the ADCPro plugins.  One examble is the joystick control SW3 and another is the green LED which informs you that the MMB3 DAC is in operation.  This is not used with ADCPro either, so that is why it turns on and then off at powerup.  This is not a general power on LED.

The 'BRD TST' and accompanying LCD display messages that appear the first time you power the MMB3 are a part of the intitial board test firmware that is mentioned above.  As Greg has already mentioned, you should use the newest plugin and TUSB3410 drivers.  The operating system should be Windows XP.  It has not been verified with other versions of Windows.  Please install all software and drivers without the MMB3 plugged into the USB port.  Once the drivers have been installed, verify that in the 'Device Manager' window that under 'Ports' the Com device shows up as a 'TUSB3410' device.  If it does not show as this device, uninstall the drivers and reinstall the latest drivers and repeat the verification process. 

Once the driver installation has been verified, unlplug the MMB3 from the USB.  Verify that the BSL switch (SW4) is in the 'OFF'  position (to the right.)  Install the ADS1248EVM on to the MMB3.  Plug the MMB3 into the USB port.  Something should display on the LCD of the MMB3 even if for a short time.  Start ADCPro and attempt to load the ADS1248EVM plugin. 

The plugin should recognize that the MMB3 is connected if you follow this order of steps.  If you attempt to load the plugin before the MMB3 is plugged into the USB port, you may have problems.  If the switch SW4 (BSL) is in the ON position when you plug the MMB3 into the USB port you will have problems.  Make sure that SW4 is off when you plug the board into the USB port.

The firmware download process begins with an information block detailing the steps needed to install the firmware. The first step is to turn the BSL (boot strap loader) SW4 switch to ON.  Before pressing the OK button in the message block, make sure you turn on the BSL switch.  If you press OK  before you switch the BSL switch you will get the 'Programming Failed' message. If you switched the BSL first and then pressed OK, the firmware should start to download.  At this point  you must wait for the firmware to completely download.  This may take several minutes to complete.  There should be a download status of the programming progress that appears in the top portion of the plugin window.  Once the download has completed, you will see another message block.  Follow each of the four instructions before pressing the OK button of the message block.  You should now have the firmware loaded and the plugin should complete the startup process.

I hope this information wil get you going.

Best Regards,

Bob Benjamin

Yes, on 3 computers i had tested, on the other one I'm not sure

 

2. When you first power up the MMB3 board, do you both see a sequence of messages?  ie "RESET", "SELFCAL", "BRD TEST" or other?  Can you describe them?

 

Yes, I wrote about this some post before -procedure what I did.

When I plug USB in on LCD I can see BRD TST - offcourese I can hear typical sound USB in computer

 

3. Can you verify that the small red DIP switch (SW4) on the MMB0 is closing?  It should measure open with switch to OFF (to the right) and a short with the switch to BSL (to the left).

Yes, I checked , switch works correctly

Greg

Please , write about communication what I sent in html file, is correct ?

Bob I will answer Your post, when I'm back - 10-12 hours - I have to check it slowly and analize this

Thank's Greg

Redgars,

Hello Greg,

1. Yes the usb connection is the only one.

2. When I power up the MMB3 board I have the BRD TEST message

3. The small red DIP Switch (SW4) is in right position when I power up up the board
