Anyone know how I can use a segger jlink mini to dump the EEPROM connected to an RP2040?

I want to make a backup of the existing binary before I flash it with a new one.

Once again, a friendly reminder to all #vintagecomputing fans to

GET THE DAMN BATTERIES OUT!

Even this small amount of corrosion on this memory battery killed a Tandy 200 by eating away about 7mm of a critical trace. Easy fix with a wire, but this could have been WAY worse.

If you own or collect old computers, go through them NOW and make sure you get all the batteries out.

I'm seeing a growing number of people with programming and PCB design skills who do not understand how file paths work.

And this concerns me.
