Power supply is normal, should also connect the TCK, TMS, TDO, TDI, pull-up resistors is 100 k, but vivado is unable to identify the chip!

CodePudding user response:

Identification chip, not just to check JTAGE circuit, also need to check the FPGA power supply, 1.0 v/1.8 v/1.5 v/3.3 v power supply is normal, if order to electricity, according to the requirement of the manual

CodePudding user response:

Could you tell me how to look on order, can use the oscilloscope to observe
