Hi Miss Zhuang,

Thanks for your replies. However based on your description, "

After working for some time, some of EPM240T100C5N's IO work is not normal, so that the camera can't get out of the picture" is too general to let us understand the actual failure behavior at your site. Board get passed after replacing the FPGA doesn’t lead us to conclude that it is due to the FPGA failure, as this failure could be due to board design margin or external factors during part replacement. Therefore, we would need customer to verify the suspected failure device on known good board. We also like to know what kind of the failure symptom exists at your site.

  • What kind of function can’t work normally?
  • Did you encounter any open/short failure?
  • Any abnormality on the power rail performance?
  • Any suspected failure pins?

Thank you

Regards,

Chia Ling
