ADS1278EVM Shows EVM/HW Incompatible

Other Parts Discussed in Thread: ADS1278, ADCPRO

Hello, I am using ADS1278EVM Rev-F with MMB0 Rev-D motherboard.

System Specs: Intel i3, Windows-7 64-bit OS, 4GB RAM

The NI-VISA driver got installed successfully but the USBStyx Driver in not installed. When I mount the ADS1278 on motherboard and connect to PC through USB, no installation window pops up. The jumpers are as described in the user manual.

I have installed the adcpro-wlvrt-2.0.1 application and then when I tried to load the ADS1278EVM, it shows a message in green color " download fail..reset the hardware "

and on reset it shows the message " EVM/HW Incompatible "

I read the post https://e2e.ti.com/support/data_converters/precision_data_converters/f/73/t/152726

but the jumper J3 and J10 on MMB0 board are not soldered on the board available with me. Also I have not connected any supply at J14.

Following are snapshots of the board

 

Please provide the updated software and drivers of ADS1278EVM on Win7 64-bit OS. Also let me know if any jumper is to be placed.

    Hello Prajwal,

    You should not have to modify the MMB0 in any way or provide external supplies in order to use the ADS1278EVM. I believe the issue may be caused by not having the USBStyx driver installed properly. You may need to point to this driver manually at the following directory:

    C:\Program Files (x86)\ADCPro\pdk_lib\libmmb0\Styx\usbstyx_drivers

    Let me know if this solves the issue for you.

    Best Regards,

    Ya I read this in one of your posts, but the problem is the USB device unrecognised is not visible in Device Manager and hence I am unable to provide the directory. This happens only when EVM-1278 is mounted on MMB0 on contrary when I connect MMB0 without mounting EVM, I can locate USB device in Device Manager. So I just thought some hardware connection may be missing.

    I tried to point the driver to Unknown Device and it gives me message "Your driver is upto date" and still shows EVm/HW Incompatible

    Hi Prajwal,

    I have still not be able to reproduce this issue. Have you been able to solve it?

    I took another look at your EVM pcb image and I noticed that all of J3, J4, and J5 have jumpers installed. This probably is ok for J3 and J5 as most of these are either channel inputs or floating pins. However, J4 is the interface header and shorting both sides of this header may prevent the software from communicating with the device. Please uninstall all jumpers on J3, J4, and J5 as per Section 2.1 of the User Guide (pg. 4).

    Best Regards,

    Ya, Thanks Ryan. It works well now, USBStyx driver is installed now. The software shows "Connected to EVM" after making jumper connections as per Section 2.1 of User Guide, . I also made modification in the "adcpro_evm.ini" file located at "C:\Program Files (x86)\ADCPro\plugins\evm\ADS1278" as EEPROMVerify=FALSE previously it was TRUE.
