Hello,

Have you tried this on other board and does it show the same result?

Thanks.

    Hi Amin,

    Well we built several boards that have this particular FPGA with the code ending in JOE & all of them have the same result on the flying probe test. They don't fail anything else. Like I mentioned the boards with the code ending in LOE, KOE, IOE all pass. We did try one of these failing boards on the functional test for the board & it failed with a "Not able to read FPGA firmware" so not sure if it got this fail message is because of the FPGA failing the flying probe test like I detailed in my first message. Is the code on the chip a lot code then? Please let me know.

    Thank you,

    Pete

      The lot code from the picture you shared with me from the earlier post is S018AF77.

      Thanks
