1) I still don't get what you want. What kind of info should EBlink write to a file from inside EmBitz?
2) Are you using the latest versions (also the latest scripts)? Somehow you are using the silabs-auto.script.
Otherwise try
EBlink -v0 -Istlink -Sstm32-auto -Fread=4@0x08000004 > resetvector.txt
P.s. I wrongly suggested that you could write flash even on running target, that's wrong. Version 3.9 will make it possible to write ram location at running targets. 3.8 can read from ram&flash (also running) but only can write to flash (it will reset before flashing)
