Raspberry Pi w/ OpenCPN

For some reason I had killed my access point functionality and decided to reinstall the OpenCPN installation from Sailoog. Everything is working fine now and looking into Oesenc plugin. Did my fingerprint change with this reinstall of opencpn on the same Pi which didn't change from a hardware perspective?

Re: Raspberry Pi w/ OpenCPN

Depends...
If you installed a complete new image, then yes, this would be recognized as a different system.

Re: Raspberry Pi w/ OpenCPN

Crap! What a big dependency this is on software changes... I couldn't figure out how to restore my access point functionality so thought let's do it the easy way. Reinstall using shift button during boot of the pi. So no other option to buy this map again from o-charts.org?

What could I have done to fix the access point functionality - switched off the wifi? (obviously it's working now again due to reinstall)

Re: Raspberry Pi w/ OpenCPN

Better to ask here >
OpenMarine

Also buy a backup SD card/usb adapter and in the Accessories menu there is a SD card copier so you can have an exact copy of a working system. Pretty sure that doesn't effect the fingerprint if you don't select "new partition UUIDs" but maybe check on their forum about that. Same team are involved with the Esenc charts and have helped me out a lot in the past by resetting the fingerprint after Pi problems.

Re: Raspberry Pi w/ OpenCPN

Thanks will post the question there as well. Via their support I received the answer reinstalling the whole thing requires me to buy the maps again. There is no way around this so I think it's strange.

MS Windows is also tied to your hardware and not to software.

Hmm, might be false memory with "don't create new partition UUIDs" when backing up onto a new card, there was some talk but can't find the posts now so might be a red herring, best check on the openplotter forums first.

Re: Raspberry Pi w/ OpenCPN

Thanks everybody. I am a Mac user so I will use the dd command in my terminal. I have verified it with a colleague at work and this should make an identical copy of the device.

I have reinstalled the device and ordered the maps again so extra 2 shots at keeping it right.

Re: Raspberry Pi w/ OpenCPN

I use Pi with SSD, wich is much faster as SD card.
Also much less change for system drive corruption when power is lost.
I mounted the M.2 SSD HAT under the Pi, connected with USB cable.

Re: Raspberry Pi w/ OpenCPN

BenS is this screwed into the underside of your nav station?
How do you connect the SSD?

Re: Raspberry Pi w/ OpenCPN

The SSD HAT is connected via USB, so its easy to mount under the Pi and the GPIO connector is free for the Moitessier HAT
I installed a 32 Gb transcend SSD in it.

I use the Pi with openplotter headless setup
Ethernet cable connects the Pi to my Windows 10 PC with Faytech touchscreen running O.

This is the M.2 SSD HAT

Re: Raspberry Pi w/ OpenCPN

Another pic from my setup
Red board is the M.2 SSD HAT
On the right a decent 5A DC-DC convertor

If you go for Pi with SSD, make sure to buy M.2 HAT and SSD
Not the older Msata type

Re: Raspberry Pi w/ OpenCPN

Thank you Ben, it's amazing how small the memory is and how much space is left on the board. Is it any faster?

Here it is in English.
