+#1350 BSN start bug
+- sometimes BSN start not the same on all BN, one or a few BN then have an offset BN
+- for FB 17352 it occurs about once per 500 BN, for FB 17783 it occurs about once per 10 BN, so it is FPGA
+  syhthesis dependend
+- ssh lcu-rtc -X "python $UPE/peripherals/util_ppsh.py --unb 0:7 --bn 0:3 -n 8" PPS stable is ok for all BN,
+  so it does not seem to be an PPS input capture issue
+- ssh lcu-rtc -X "python $UPE/peripherals/pi_bsn_scheduler.py --unb 0:7 --bn 0:3 --cmd 0" shows the offset.
+  The offset can be e.g. (note 800000 = 1.024 s)
+    285351
+    266642
+    257682
+    279232
+    275006
+    300636
+- the offset is nearly the same for all BN, even if they are on different subracks, so there is some central
+  relation, because how could all those offst BN have (nearly) the same offset
+- power cycle dish uniboards, does not help
+- ssh lcu-rtc -X "python $UPE/peripherals/util_bsn_source.py --unb 0:7 --bn 0:3 -n 7" reads current BSN @ sync
+  and these are all equal.
+- ssh lcu-rtc -X "python $UPE/peripherals/util_bsn_source.py --unb 0:7 --bn 0:3 -n 2"       stop BSN source
+  ssh lcu-rtc -X "python $UPE/peripherals/util_bsn_source.py --unb 0:7 --bn 0:3 -n 11 -r 0" init BSN
+  ssh lcu-rtc -X "python $UPE/peripherals/util_bsn_source.py --unb 0:7 --bn 0:3 -n 4"       restart BSN source on PPS also
+  keeps on failing to restart all BN at PPS with same BSN
+- is the bsn_init value written correctly? this cannot be readback.
+- check synthesis report on 'latch', 'sensitivity'
