INA228_237_238EVM: SCM Board not recognized

I see my board just bought from Mouser is an older SENS063B which seems to be completely different and undocumented by sbou241e.pdf from the current SENS064A that is.  Where is the documentation on the older board version?

Hi Daniel,

The board you acquired is also supported by our GUI, it just requires you to enter DFU mode on your EVM for the initial update. Instructions on how to enter DFU mode can be found on the EVM user's guide located here: https://www.ti.com/lit/ug/sbou241e/sbou241e.pdf. The section on this can be found in section 4.2.1.(Setup). The screenshot in the user's guide is of the INA229, which is a SPI device. The SPI devices interface with the GUI using the CS1-4 connections rather than the addressing connections. Please let me know if you have any further questions!

Best,

Thanks Mohamed,  I was out of town for a week and getting back to this.

Nothing's worked, I tried everything to get into DFU mode to upgrade the drivers.  I did manually load the driver which moved the Generic Bulk Device into MSP432 Bulk Devices in Device Manager, but that didn't help.  I also tried loading a fresh Win 10 on a different PC, and put the drivers on that, also didn't help.  Also used the tweezers to short the holes while pushing Reset, also typing that command into the com port as well as changing the com port.   Nothing worked.  All com ports I change to in the GUI say "incompatible" regardless of settings or whether I have the EVM attached.

I'm running v 2.1 of the GUI, also tried earlier versions.

How can I tell if the SCB board is defective?  The lights are on, and a light on the EVM.  But I'm out of options to try.  Either the SCM board is defective, or the GUI software, or both.

Frustrating!   Thanks,  Dan

It's the same problem as https://e2e.ti.com/support/amplifiers-group/amplifiers/f/amplifiers-forum/1198304/ina239-evm-scb-connect-fail except I can't get it to go into DFU mode.

Hi Daniel,

When you power up the SCB, which LEDs are on? After you attempt to enter DFU mode by shorting the pins and pressing reset, which LEDs are on? After you enter DFU mode, only D5 should be on, or DFU did not enter correctly. If only D5 is on, it is possible that you are in DFU mode. You may have to long press the reset button while shorting the pins to enter DFU mode. To confirm if you are in DFU mode, you can look at the device manager to see either TivaWare DFU or Stellaris DFU. If you are not in DFU mode, then the drivers need to be set for both the Generic Bulk Device and the USB Serial Device separately. 

To clarify, is your SCB controller labeled as "TI Sensor Control Board" or "Precision ADC Motherboard"? When you plug in the controller initially, are the LED lights cycling or solid? If they are cycling, wait for them to finish, then the controller will enter DFU mode automatically.

Mohamed:   It's labelled "TI Sensor Control Board".  When I plug in the controller initially, LEDs D1-D4 cycle continuously and never stop, plus D5 is steady on.  After I short the DFU pins and long-press reset, it's the same, no D5 only.  I have loaded the drivers for the Generic Bulk Device so it shows up in Device Manager under MSP432 Bulk Device, and it shows up as a COM3 USB Serial Device w/o loading any drivers which I set in Device Manager to 115200.  Thanks,  Dan

Hi Daniel,

It seems like there may be an error code. Can you send a video of the LEDs flashing for me to confirm? Ideally the video would show the pattern repeating at least 5 times. 

Best,
