Hello,
I’m trying to test the RFSDK (demo4 – DAC38j84 & ADC32RF45) with a custom signal. I'm using the RFSDK version 2.0.6.
I have some questions on the process:
- I don’t have the K2L-HSP FMC adapter card. Is it a must? Or can I use the second Lamarr JESD lane? What are the difference in configuration? How do I connect the cards in this configuration?
- I was given a Python script and a cfg file that are designed for LTE60 in order to create a custom signal. Demo 4 is using LTE75, is it an issue or will it work just the same?
- When I’m using the JESDlpbk configuration I see that I managed to load the custom signal into the TX DSP but the TX DFE shows nothing. What might be the reason for that? How can I fix it?
- When I’m using the normal demo4 configuration I receive this message in the command prompt:
root@k2l-evm:/usr/share/radio/tests# radio on 18300 300
Turn the AFE on, and check its JESD RX status. Then press RETURN.
Traceback (most recent call last):
File "/usr/bin/radio", line 108, in <module>

rfsdk.Error: dfeService.DfeStartRx() API call failed with status 'RFSDK_API_RESULT_DFESVC_JESDRX_SERDES_LANE0_TIMEOUT' (42).
I also receive this message (42) when trying to use the GUI option.
I configure the DAC38J84 using the cfg files provided in the RFSDK. How do I configurate the ADC32RF45 and how do I connect it, is there a guide or documentation on the subject? Which configuration file to use?
5. What are the memory address for each step of the demo?
Thanks in advance,
