Original question:

CDCI6214EVM: ticspro issues

CDCI6214EVM: CDCI6214EVM

Part Number: CDCI6214EVM

I am having the same issue as described here:
https://e2e.ti.com/support/clock-timing-group/clock-and-timing/f/clock-timing-forum/680535/cdci6214evm-ticspro-issues

That issue is marked as resolved, but the resolution does not appear to be in that thread. Can you please let me know how I can get the MSP430 on this evaluation board to communicate with the I2C device.

When I tell the board to "Scan I2C Bus" under the USB Communications -> Interface dialog, it just says "No Device Found" and accordingly the software is unable to write registers to the device.

Thanks,

Eric

    I looked a little closer at the chip, and I could see that the pad for GPIO3 was not making a solder connection to the chip. I removed the chip and cleaned up the solder work, and now that the chip is back on TICS can discover the I2C device.

    I was a little surprised... Does TI not do QC testing on their EVMs?

    This issue with too much solder on the ground pad is sometimes called "skating", I think TI might want to reduce the paste opening for this pad in their next run of the design.

    Best,
    Eric

    Hi Eric,

    Glad to hear that you have "resolved" the problem. 

    EVMs are not produced in-house, we will notify our vendor to ensure quality is up to everyone's expectation.

    Apologies for the trouble caused.
