Part Number: MSP430F5529


Tool/software: Code Composer Studio

HI! 

I am trying to get the MSP430 USB Firmware Updater python software to work on my Mac. I can scan and connect to my MSP430 in BSL mode, but when I flash I get this error:

opening HID device <hid.device object at 0x105453330>
Mass erase...
Exception in Tkinter callback
Traceback (most recent call last):

return self.hid_device.write(data)
File "hid.pyx", line 82, in hid.device.write (hid.c:1789)

Thanks in advance! 

Kind regards,

    Hello Ramtin,

    Did you follow the installation steps (shown below) that were found in the ReadMe HTML file from the download package? also did you run the program in sudo/root?

    To install the packages required for the tool to run on Mac:

Python(2.7.9+)
Cython-0.22
In command window, navigate to Cython directory and run the following command:
                             python setup.py install

Cython-hidapi
In command window, navigate to Cython hidapi directory and run the following commands:
                           python setup-mac.py build
                           sudo python setup-mac.py install
To run this from Linux or Mac, sudo or root is required as it needs to write to a raw HID device.   Example invocations:


Windows (After installing Python and pwinusb)

 

 All examples are in a command window  from the  MSP430_USB_Firmware_Upgrader directory 

 

GUI

set PYTHONPATH=.\python-msp430-tools& python TargetGUI.py 

 

Command Line

set PYTHONPATH=.\python-msp430-tools& python -m msp430.bsl5.hid_1 -e -v -P ./5529_LED_Blink.txt

Linux and Mac

 

 All examples are in an xterm window  from the  MSP430_USB_Firmware_Upgrader directory 

 

GUI

sudo PYTHONPATH=./python-msp430-tools python TargetGUI.py

 

Command Line

sudo PYTHONPATH=./python-msp430-tools python -m msp430.bsl5.hid_1 -e -v -P ./5529_LED_Blink.txt

    Hello .

    Yes I have followed the installation instructions and I run it with sudo but it still does not work.

    Regards,

    Hello Ramtin,

    When you get the error you listed above, are you trying to download the Blink LED example packaged with the tool or are you trying to flash your own custom TXT file?   What version of MAC OS are you on?

     

    Regards,

    Arthi Bhat

    Hi ,

    I tried both files. I’m on Mac OS X High Sierra 10.13.5. Any ideas?

    Best regards,

    Well, is it possible to find in which directory the hid.c or hid.pyx file is in that the program is failing at on your computer?

    By any chance did you run the 'setup.py install' command from the python-msp430-tools folder also? The python-msp430-tools folder also contains a setup.py file but this one should not be installed.
