Other Parts Discussed in Thread: AFE7906, AFE7900EVM, AFE7900,
Hi,
we have AFE7900EVM with TSW14J57EVM boards and try to start testing possibilities of AFE7900 chip according to AFE7906+TSW14J57.pptx guide. All is going well before we starting to capture data from HSDC Pro: after the start of capturing it works from 5 secs to 4 mins (record, 30 secs in avg) correctly then TSW14J57EVM resets without any errors messages etc. and if we ran with "continuous capture" option we get some random error in moment of FPGA reset, so i dont think this errors are the main reason. We also tried AFE7900+TSW14J57.pptx guide sequence and got similar problem after "Send" step in the TX AFE window: it notifies us about setting new speed for jesd, working 5-10 secs (status LEDs blinking) then all LEDs goes off and boards restarts. At the same time AFE7900EVM boards continue working well without any complaints.
I also read on this forum that on old TSW boards it happened due of voltage drop (they had 5V and when the voltage got to 4.9V it started to reset) so we tried and set voltage to 12,5 V level, but id didn't help.
Here some error logs that we have get at this moment (all after FPGA board starts restart) /cfs-file/__key/communityserver-discussions-components-files/73/8255.Error-log.txt

Thank you for support
