incidental: is there a firmware on the module? doing backup needed?

[rudi ;-)]

hi,
only question before flash first time, is there a firmware on flash?
do we need make backup/dump from flash before flash own firmware?
can we clear with blank or are there key pair / tags for later things that are need?

for all cases, will make backup from flash.

thanks!
best wishes

Hey rudi, there is ssc program in flash. Just for function test. No need to backup. You can start with SDK directly!!~
