I'm using ADC12J4000 with TSW14J56 EVM(rev D and B(before)). and I want to receive some GNSS signals with these.
But there are some problems to resolve.
When i capture data at HSDC pro, errors occur.
'Read DDR to file
TIMED_OUT_ERROR
Possible reasons for Time Out Error.
1.FPGA may be in reset.
2.Clock from ADC EVM is not received by TSW board. Please check if D4 LED is blinking.
3.SYNC is not established between ADC and FPGA. Please check if D3 LED is OFF. Possible reasons for SYNC Failure.
a.JESD Ref clock Input Frequency to the TSW board from ADC EVM is not correct.
b.JESD configuration is not same in ADC and the INI file selected'
and LEDs of TSW14J56 EVM are in this status.
D1 = ON
D2 = OFF
D3 = ON
D4 = OFF
D5 = OFF
D6 = OFF
D7 = OFF
D8 = ON
How can I approach with this problem?
