Hi - The update instructions only refer to updating an OCTOPUS.  I have a NEMO, will these instructions work the same?  If anyone has any Mac OS specific update instructions, that would be greatly appreciated.

thanks!

Eric

Hi Eric,

The upgrade path for the Nemo is the same as the Octopus except............

For the Nemo you would change the command in item 4. Write the new OS file to Octopus flash to.....

     fis create -b 0x00010000 -l 0x00070000 -f 0x01820000 NEMO_OS.elf

 

Best

Jean

Hi Guys,

I added a new post with this but thought I would add it here as well as it may notify people!

 

I am having troubles updating my Blue Nemo, the modem transfer always fails at exactly the same place (294k), I have tried on a Mac Desktop, Ubuntu VM and a Mac laptop.

Sending: NEMO_OS_v500.elf
Ymodem sectors/kbytes sent: 2353/294kRetry 0: Cancelled
Transfer incomplete
Entry point: 0x00010040, address range: 0x00010000-0x000518b4
xyzModem - CRC mode, 1(SOH)/295(STX)/1(CAN) packets, 3 retries

I have used the mfill and dump commands to verify the ram is ok, no problem there.

Anyone any ideas?

Many thanks

Andy

Hi Andy,

I'll try to help out. Let's first verify your terminal settings. Maybe it is trying to transfer too fast. I don't know if you have done this before but there is a timeout after you issue the command to upload the OS file where you have to quickly select the ELF in the Finder. Here are my settings (see attached).

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

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, 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. 🧐

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.

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.

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

The boot from memory address is   'go 0x00010040'

@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
