INA226EVM: Unrecognized EVM

Michael Chhay

Tool/software:

I believe I have problem #3 as listed in this TI thread https://e2e.ti.com/support/data-converters-group/data-converters/f/data-converters-forum/916049/faq-warning-you-are-connecting-to-an-unrecognized-evm-error-message. I do not know how to fix it as I keep getting the "unrecognized EVM" message.

Hello Michael,

Thank you for using the TI forum. It is possible that you just need to update your firmware and/or driver. Please follow the steps in the suggested answer from this post:

https://e2e.ti.com/support/sensors-group/sensors---internal/f/sensors---internal-forum/1319536/ti-scb-can-t-do-fw-update

If the firmware won't update after following those instructions, then follow the E2E link that will point to some other E2E threads that have some helpful tips and suggestions to resolve common driver/firmware issues.

If none of those work, then let me know and we can look into other options.

Regards,
Mitch

Hey Michael,

Sorry, I didn't realize that was an internal link.... Here is the relevant info from that thread:

Before trying to associate the driver, first try this:

Connect the EVM to the SCB controller
Plug the SCB/EVM into the computer
Launch GUI
Close the readme popup
When you see the "Update Firmware" dialog, close it instead of saying update.
1. Close any other popups
Click the "Connect" icon on the bottom left corner of the GUI. It looks like this:
2. You may have to try this a few times until the connect indicator turns green:
Go to File > Program Device...

NOTE: If you can't get the green connect indicator on step 6b, try the process again with the EVM disconnected. In this case the green connect indicator will show connected to the TI_SCB.

NOTE: If the firmware update fails for any reason, power cycle the device before trying again.

If that does not work, try to associate the driver manually. Here are some specific steps for that:

Before launching the GUI, plug in the SCB (with EVM connected) and enter DFU mode with the test points per the User's Guide (ensure the LEDs 1-4 stay off (only the power LED should be on)).
Go to the device manager and find the device that says "Device Firmware Update", such as this example:
2. (It may say Stelleris instead of TivaWare
Follow these instructions to associate the driver: 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
1. For step 8, only select "boot_usb.inf"
After driver is associated, power cycle the SCB and follow step 1 again to enter DFU mode.
Launch the GUI and close the README.md popup
1. You should see a box that says "No SCB controller detected". Close this box.
2. The homepage should say "DEVICE DISCONNECTED" and have a red icon.
Go to File -> Program Device...

Note that if a firmware update fails for any reason, then the MCU will need to be power cycled before it will work again.

Sometimes other devices on the USB hub can also cause problems, see this thread for an example:
