Hello,
I understand that the ESD test are done on a custom board with FX3 programmed with custom firmware. Is that correct?
Please program FX3 with default bulksrcsink (path :Fx3 SDK Installation path\Cypress\EZ-USB FX3 SDK\1.3\firmware\basic_examples\cyfxbulksrcsink) firmware of the latest SDK and then perform the ESD test and let me know the results
