INA228_237_238EVM: Firmware Update Unsuccessful

Hello Lee,

Please see the e2e thread: https://e2e.ti.com/support/data-converters-group/data-converters/f/data-converters-forum/914940/faq-how-do-i-resolve-pamb-evm-connectivity-and-or-driver-installation-issues

It is possible that there is a driver issue or a USB hub issue. Per the thread above, ensure that the drivers are installed correctly. Also, try plugging the USB connector into a different port (if you are using a pc, try a port on the back of the pc).

Regards,

Mitch

Hi Mitch, 

Thanks for the reply. I had tried the e2e thread shared, but it doesn't work and same issue happens.
Other than that, I'm not using an PC, I had tried plugging into different USB port in same laptop and tried with different laptop USB port.
Similarly, that doesn't work as well.

Hi Mitch, 
I am helping Yee Yong to make the EVM work. 

I see the same behaviour as him:

-I've tried the steps until File--> Program Device. This does not work, because my button is greyed out

My windows is Windows 10

Tiva Device Firmware Update with a warning sign is shown in Device Manager

Another funny thing... I went back and opened GUI 2.0.0, and it works. 

GUI 2.1.0 does not. Perhaps this is a good starting point?

Hao,

Mitch is out sick today. I have informed him of this thread and he should follow up with you when he is back in office tomorrow. 

Hello,

Just to clarify, when you connect to 2.0.0, you can go to file->program device, and it updates properly, but then when you connect to GUI 2.1.0 (after a power cycle of updating to 2.0.0), then it does not?

Try this: After loading the firmware from 2.0.0, power cycle the EVM then run the 2.1.0 GUI. It will prompt you update the firmware, click update. If this fails, then click connect again on the bottom left corner (so that the homepage shows a green icon), then go to file -> program device.

If this does not work, try reinstalling the driver. I notice that from your screenshot there is a warning sign next to the driver. When updating the driver, put the device in DFU mode first, then manually associate it with the boot_usb.inf file as shown in this FAQ: https://e2e.ti.com/support/data-converters-group/data-converters/f/data-converters-forum/914940/faq-how-do-i-resolve-pamb-evm-connectivity-and-or-driver-installation-issues

With GUI 2.0.0, I do not have to update the firmware, and it works straight out of the box.
With GUI 2.0.0, File->Program Device does not work:

I then associate the boot_usb.inf file, and the warning sign is gone:

but Program Device through both GUI2.0.0 and 2.1.0 are still unsuccessful. But I can still use GUI 2.0.0 without any updates.

And if it helps, the Firmware is 1.0.0.2 it seems.

Hello Jie Chan,

Glad you found the issue! I was not going to think to check for that!

Regards,

Mitch
