@jean ah. I see. I changed the file name bc I was using the full file name of the download and it was too long. This makes sense. I’ll try that

Hi, I see from you screenshot you have typed the filename 'NEMO500.elf - the fis create name must be NEMO_OS.elf (even if the file you have loaded into flash has a different elf name).

Best,

Jean

I think that means v1.6 which wouldn't have the upgrade issue.

Probably the next thing to do is upgrade without running the last step to flash. You can boot in-memory instead. I don't have the run command in front of me but I know Wilson had posted it here somewhere when helping someone else.

Don’t have the unit in front of me at the moment but it I remember correctly steps 1-6 were lit red and I believe step 9 was lit red.

Hi, there are some extra upgrade steps if the Nemo is running a really old OS version. Can you restart in System View and check which OS version is currently installed. Post a photo if the LEDs don't make sense. 🧐

Trying to update a friends Nemo to CE and keep getting error below in hyperterm. Using Windows XP. No problems a few years ago updating a octopus and Nemo with same system.

“Invalid flash address - not free”

any suggestions?

Hi Eric,

Thanks very much for the post.

Terminal settings are the same here and I am sending the file pretty quickly, one "C" has been logged.

I have tried forcing ymodem mode and binary mode: lsz -b --ymodem ...

It's just really strange it cancels at exactly the same place on each machine, all are using lsz though.

I'm trying to track down an XP VM I have somewhere to try hyper term, otherwise I have JTAG gear here so I could maybe rip it apart and use openocd, that at the moment is last resort though :)

Cheers

Andy
