MSP-EXP430F5529LP not recognized in CCS "No USB FET was found"

Other Parts Discussed in Thread: MSP430F5529, MSP-EXP430F5529LP

Hello,

I recently purchased a MSP-EXP430F5529LP (LaunchPad eval board with MSP430F5529) and have not been able to program it through CCS. Additionally, the demo program that is supposed to run (according to the quick-start guide) does not show up in any form.

I've read several posts regarding similar issues but have not been able to resolve my problem with the suggested solutions.

Here are a few pieces of information that might help determine what the issue is:
1) I've tried with CCS 5.4, 5.5, and 6.0, each time completely uninstalling any other versions
2) I'm running Windows 7 x64
3) When I first plugged the board in, windows installed drivers, but only for "HID-compliant device" and "USB Input Device"
4) It is listed in device manager as "Generic USB Hub"
5) It shows up as two "USB Input Devices" in my control panel's 'Devices and Printers'
6) I have a MSP-EXP430G2 LaunchPad and it has worked correctly the whole time (i.e. it shows up as a TI MSP430 device and I am able to program it through CCS)
7) The device ID (according to USB Device Tree Viewer) is "USB\VID_2047&PID_0200"
8) I've tried plugging it into several different USB ports with no change to the problem

One of the other posts I read (http://e2e.ti.com/support/microcontrollers/msp430/f/166/t/296908.aspx) suggested that it may just be a faulty board, but I wanted to get some more opinions before I go that direction.


Best regards,
Anthony

    Hello Anthony,

    It looks like the board comes up in BSL mode as indicated by the VID/PID of 2047/0200.   When you connect the board to the USB port, are you holding down the S5 switch?  This switch puts the board into BSL.

    Try pressing and holding down the RST switch (S3) while the launchpad is connected up to the host (or powered) for about 2 seconds.  Device manager now should show 'T1 MSC LUN0 USB Device' under Disk Drives category.  In addition, you should see the Mass Storage Device in Windows Explorer.  

    If the above does not work, bring up CCS 5.5 or greater and then download M1 example from View->T1 Resource Explorer -> MSP430ware->libraries->USB Developers Package ->Example Projects -> MSC (Mass Storage) Examples->M1_FileSystemEmulation to the launchpad.

    Regards,

    Arthi

    Arthi,

    Thank you for your reply.

    I have not been pressing or holding any of the switches as I plug the board in or try to program it. Your suggestion, however, made me curious and I checked S5. It seems that the voltage on both sides of the switch is 3.3V, where as only one side should be. According to the schematic that switch should pull up the TARGET_PUR line, but because there seems to be a fault somewhere, I think it is constantly booting into the BSL mode. I de-soldered the switch and the switch seems to work properly, but the two terminals on the board are still at the same voltage. Do you think this could be the problem?

    Also, I tried holding the RST switch and it did not help. The board still comes up as a Generic USB Hub.

    Finally, I downloaded the File System Emulation (although, it was called "Single-LUN - File System Emulation), built the project, but couldn't program the target, as was my original problem.

    Can you think of anything else I should try?


    Best,

    Anthony,

    The 3.3v on either side of the S5 switch is correct even if you do not press the switch. 

     What version of launchpad do you have and what type of error message do you get when you try and download the 'Single-LUN-File System Emulation' example?

    Regards,

    Arthi

    Arthi,

    It is the Rev 1.5 board.

    I have no problem loading the example and compiling/building it, but I get the same "Error initializing emulator: No USB FET was found" message when I try to program it as I did when I first discovered the problem.

    Arthi,

    A colleague of mine just attended a conference where he received another MSP-EXP430F5529LP board. I plugged it in, the light came on, the drivers installed correctly, and the demo worked without any problems.

    I was also able to write a quick program and during my first debug, was prompted to update the firmware, which succeeded successfully and I was then able to debug/run my code.

    Considering I wasn't able to do any of the above, I'm going to RMA my first board and assume I was subject to some random manufacturing defect.
    Thank you for your help

    Hello

    I am trying to use MSP-EXP430F5529LP with IAR. 

    I downloaded a very simple LED on/off program and it gave a fatal error, I tried multiple times and it failed all.

    I am not very interested in the program that was preloaded, I just want to download personal programs.

    What is the right way to do?

    Thanks

    Hello,

    Is it possible to start a new thread on your issue?  The original question has been verified multiple times.

    In regards to your question - what type of error is IAR listing?  Can you paste your program in the new post?

    With the MSP-EXP430F5529LP, emulation and dowloading application firmware is done via the USB connection.  There is no need for a FET. 

    Also did you connect the jumpers per your power requirement?

    Regards,

    Arthi Bhat

    Hello

    Issue resolved. Before opening another thread on this...

    I was trying to connect the 5529LP board to IAR versions 5.51 and 5.52.

    Failed every time - gave a Fatal error.

    Following process solved it.

    1. Uninstalled the MSP related drivers under COM port in Device Manager in Windows

    2. Disconnected the LP board

    3. Downloaded newer free code limit version IAR 6.10.

    4. Restarted the PC

    5. Reconnected the LP board

    6. It auto installed the new drivers

    7. Opened new IAR, made settings in options for 5529, downloaded the program.

    It worked.

    Thank you.
