Thread: Nanocom Evolution SD Card not reading

Maybe people should post what SD cards have worked for them.

I can say that the following once did not work for me:
- SanDisk Ultra 2gb
- SanDisk 2gb MicroSD (with adaptor)
- Kingston 2gb MicroSD (with adaptor)
- MyFlash k Data 512mb SD
- Toshiba 256mb SD
- Toshiba 128mb SD

I have formated each card as FAT using Windows XP, Windows 7 and OSX.
In each case no joy, every card worked fine in a card reader and worked fine in a digital camera.

I guess I should try a card that is know to work - anyone on Sydney's Northern Beaches? - and if that still does not work it must be a hardware issue with the in-build card reader.

Thanks for popping-in Colin

So the device is a bit fussy eh!

As you recognise some of us are struggling to find a working solution that will allow us to use what is an important part of the device's functionality.

May I suggest (and as Pedro posted above) that you give us the details of the exact card (brand and size) and format that you guys use and recommend. At least then we will have a baseline from which to proceed.

I bought a Kingston 2GB SD Card yesterday, and it works fine.

BTW - incase anyone had a thought of trying a bigger card, they dont work.

Had a spare 4GB card, but the Evo would not read it.

Hiya one_iota

I never really tested the Evo on different SD cards and posted my initial thoughts based off ;

1) The reports of troubles here
2) The fact that only certain card(s) have been recommended
3) My own fear of such standards not being as they should, and microcontroller systems typically being very exacting.

However, in respect of ;

1) There has to my knowledge never been any previous reports of SD card problems.

2) Someone can only recommend what they have tried and it is likely that not many were availaible for testing at that time and the recommended ones have never been added to.

3) I have not actually looked into how robust and adaptable the code is for the SD cards function and as a software engineer, may be imagining it to be less caable than it really is.

This morning, i collected together as many cards and variances as i could, 6 in total, all previously used in cameras, PDA's MP3's, SAT NAV's etc and tested them in the Evolution. I only plugged them in and connected the Evo to windows with a USB cable to check the contents were reported by the EVO as being the same as when the card is plugged directly to the PC.

I could not find anything that did not work

The ones i tried were ;

1) Kingston SD card to Micro SD card adaptor with 2 GB Kingston Micro SD SDC/2GB110
This is what i had supplied with my Evo and is what we will be putting on our Web shop

2) Adata SD card to Mini SD card adaptor with 1GB Adata Speedy Mini SD card

3) Peak hardware 3 in one MicroSD+USB+SD card with a 1GB Micro SD card. Basically an adaptor that provides a slot for a Micro SD and a USB and SD card connector

4) An Adata super SD Duo 2GB SD card with a USB connection

5) A cheapo Maxim 2GB SD card

6) An Adata 2 GB Speedy SD card

So from my experiment, it seems the Evo is not that fussy.

The 2GB is a known FAT barrier, so i don't expect anything above that to work.

Hope this helps

Thanks for following up on this Colin.

I'll try option 1.

sandisk 2 GB $8.70 office works ok so far

I thought i was formatting a old sd card but i think I formatted nanocom memory and lost all data nanocom will not work tells me files are missing

when I brought new card the card worked ok but when pugged to power it would not start

Sandisk 2Gb SD card is working for me.
