AFE7769DEVM: AFE7769DEVM Software Bootup

Hi Josh,

Thank you for reaching out regarding the challenges you are facing when connecting to the TSW14J58 FPGA EVM. Please try the following debug steps:

1. Ensure that the male USB A connector of your USB A-to-USB C or USB A-to-USB Micro B 3.0 is plugged directly into the PC.
   1. Strictly do NOT use a USB hub when connecting to the FPGA. 
   2. If you are already connected directly to your PC tower USB ports, connect directly to the motherboard/rear I/O USB ports. Connecting to the front I/O may cause issues on some PCs.
   3. 
2. Check cable data transmission using an unrelated device,
   1. Ensure the cable itself is functional by connecting another known good device that has USB C or USB Micro B 3.0.
   2. Try to copy files between your host PC and the target device.
3. Reset the USB FTDI using the two buttons provided next to the USB port on TSW14J58 EVM.
   1. Double click and hold the two white push buttons located nearest to the USB port on the EVM.
   2. 
4. Update Drivers
   
   1. Visit https://ftdichip.com/drivers/d3xx-drivers/ and download the driver pack - when you unzip the file, you should have a .cat, .inf, and .sys file.
   2. 
   3. Navigate to device manager (you have done this already and have included screenshot - perform the exact same action).
   4. Since we do not know which device the USB 3.0 is displayed under (because the drivers may be incorrect) when you navigate to device manager, unplug and replug the USB cable connected to TSW14J58 FPGA EVM. This should cause a change in listed items under Device Manager -> Universal Serial Bus controllers. Since the only device you are disconnecting is the TSW14J58 EVM, we know the changed item must be updated. 
   5. Right click on the changed item -> Update Driver -> Browse my computer for drivers -> Browser -> Select the driver files you have downloaded (.cat, .inf, and .sys)
   6. Continue driver installation, reboot PC, and disconnect/reconnect the USB cable.

Please let us know if the issue persists on following these steps.

Best, 
Karan Venaik. 

Hi, Karan:

        Thanks for your support. I followed your instructions and switch to another laptop with sufficient USB ports and installed the driver successfully. But I encountered a python issue as below. I tried to install python 2,7 but the issue remains. Please kindly advise

Josh

Hello Josh,

Thank you for trying out the debugging steps - I would like to follow up on,

1. Do you see the TSW14J58 FPGA Capture Card EVM recognized under the Windows Device Manager, and in Latte's list of USB Handles?
2. Do you also see the AFE7769D EVM recognized under the Windows Device Manager, and in Latte's list of USB Handles?
3. Can you please post the full error log shown in your image above - I would like to understand at which point the path failure happens. 

Best, 
Karan Venaik. 

Hi, Karan:

        Thank for your support. The snapshot of my Device Manager is , So I think both boards were driven correctly. The full error log is as below for your reference.

Hi Josh,

Thank you for sharing the context - here are a few points based on what you have described, 

1. The driver issue has been fixed and it seems the application can now communicate with the AFE7769D EVM - this is a positive.
2. With regards to the Latte environment Python error code,
   1. You do NOT need to install Python separately; Latte is effectively "containerized" and performs setup of the software it requires to operate.
   2. I see the path "C:\TI\lib\Afe77xxDLibraries\__init__.py" - did you per chance change the install directory of Latte?
   3. Please uninstall Latte in its entirety/completely, and ensure no Latte files are leftover. Then, redownload Latte and reinstall at the default directories it suggest (Just keep clicking "next" without changing anything).
   4. Once Latte is installed, power cycle your computer, and the two EVMs. Then reconnect the EVMs to USB after PC boot up. 

Please let me know if #2 fixes the issue, and you can connect your EVM with Latte. 

Best, 

Karan Venaik. 

Hello Josh, 

Thank you for confirming that Latte is now working - can you please confirm on the following points,

1. Can you bringup the AFE7769D device fully?
2. Can you please describe the different Region/Language Settings change you have performed during initial bringup which caused Latte to be installed to a different folder path? If possible, please provide screencaptures of choices made during installation procedure that installed Latte to the "C:\TI\..." filepath. We would like to review this. 

Best,

Karan Venaik.

Hi, Karan:

        1.Unfortunately, I still encountered two errors after I click 'Run Device BringUP'. The full log is shown as below: The power supply I am using can only support 3.2A@5.5V, could it be the root cause?

        2. The region on the laptop is set to Taiwan and Traditional Chinese feature is installed. The path was pointed to a directory under One Driver, whose name contains two '?' characters. That's why I could not stay with the default configuration. I compared the setup in my own laptop (Interestingly I did not encounter the same issue with the same Region/Language setup), I manually input 'C:\Program Files\Texas Instruments\AFE77xxDLatte\' and the issue was gone.
