For Fx3 to enter compliance mode, please connect 50 Ohm resistors to ground on both SSTX+ and SSTX- lines.
Now probe the SSTX+, SSTX- lines using an oscilloscope. They will now send the Cp0 Pattern.
(Some oscilloscopes have the provision of having an internal 50 Ohm inputs)
The CP0 Pattern of FX3 is given in the FX3 TRM
Please refer LNK_COMPLIANCE_PATTERN_0 register. (Address = 0xE0033138)
Thank you so much for your reply!
I still have a doubt.
I find the CP Pattern(CyFx3BootUsbSendCompliancePatterns) in the Firmware API,should I add it to my Firmware project?
