[TG] [TG11] Upgrade to Lighthouse 3

[Tom - Raymarine - Moderator]

Hello Ktklaw,

Sorry for the delay replying.

On the ray_mfd_AtomCartographyRX5v1_22.upgrade.iso: don't worry about this, it's a known issue that under some circumstances you can get a false fail message on installing this specific upgrade package. It's being investigated by our engineering team, but if you install it again you will see that the upgrade process gets to 100% and then restarts normally. You can ignore that error without risk.

On the pilot upgrades: there is no benefit to updating from v2.18 to v3.01 in an EV sensor core. v3.01 only existed to support running hardware changes in the EV and does not have any effect at all on operation. To upgrade, you should use v3.02, although the actual changes in this version are minimal: see here for details of what's changed.
It is possible that the EV1 is not upgrading from v2.18 to v3.01 because that specific version is not relevant (not an upgrade) for your revision of EV1: the upgrade process does do that sort of checking.

That wouldn't be the reason why the p70S is upgrading though - if you're seeing problems with both, this is usually a card or card-data problem. In order of increasing likelihood:

1. corrupted download to your computer
2. incomplete extraction from Zip file on your computer
3. failing MicroSD card (bad sectors on the card: SD cards in made in very large numbers at very low cost and have a high failure rate)
4. Incomplete write to the card (when your computer's download progress bar reaches 100% and completes, that doesn't mean that the download to the card has really completed, only that it's been loaded into the output buffers. Computers use 'cached writes' to SD cards in order to reduce wear on the flash media which has a finite number of read-write cycles.)
   

I'd try another card, with a fresh download, and make sure that you right-click and do Eject on your PC before you remove the card. Also make sure that the new card is formatted with FAT32 or NTFS rather than ExFAT filesystem. If you search online for 'Format' FAT32' you'll find lots of information on this. Make sure that you DO NOT format your Chart card or any card with data that you want to keep on it: formatting will erase everything.

Regards,
Tom
