Hello,

I have problem with my TL-SG3216 switch and I can't boot it. When I try to do this it stops with "Rsa verify fail." I've tried to restore default configuration in bootutil as well as upgrade with latest firmware version but it always fails with "Rsa verify fail" communicate. Have anyone similar problem? Is there any solution to bring that switch to live?

Here is small debug info:

- normal boot

Press CTRL-B to enter the bootUtil
