Hi Stephen,

If you erase your Netduino Plus and reflash it with the "regular" Netduino firmware, it'll disable the networking and SD card.

If you do this, be sure to flash both the TinyBooter bootloader and the .NET MF runtime (TinyCLR).

Hello Chris
Thank you for your quick reply. What I was thinking of really was effectively re-setting the network chip via software. My Socket.Connect command seems to hang my netduino plus quite frequently. I've tried various different work rounds and the one that seems to work best, so far, is to connect when I get a NetworkChange_NetworkAvailabilityChanged event which currently I can only generate by plugging and un-plugging the network connector. I was thinking of booting up with network off, switch it on, get the event then connect.

Regards
Stephen

I'm not sure if this is going to be useful but I had very similar problems with my netduino plus but they all went away after I bypassed my 10BASE-T hub. The hub which appears to have been causing the problem is not in my office here so I haven't been able to re-connect it to verify that it was definitely the problem but I would suggest if you are having issues try avoid the hub. Hope that helps a bit. Cheers Stephen

Stephen,

Are you jumping pin D4 to pin D10? This may conflict with the Ethernet chip if you're using the SPI header...

WP is not used on MicroSD cards. What error are you getting when you try to write to the card?

Hi Stephen,

We will have an update later in November which will enable the chip select. If you need a special build which uses pin D4 for SD chip select, we could make one and post it here in the meantime to get you started...

Hello Chris

Thank you for you rapid response.
Note: I'm confusing the issue by having two threads open on the same topic so I'll suggest we just follow this one.

I would love a special build now but to be honest can't claim it is really urgent so I'll let you decide. I guess there might be a few other people using the same card as me so it possible others would benefit as well?

In fact I think I can cut the tracks on the SD/Ethernet card and swap the chip select lines. That should get me going in the mean time and prove where the problem lies. Given this is still development and you plan to update the firmware quite soon I think that is a solution.

Thanks
Stephen

Update. I did swap the CS lines round. I couldn't get the W5100 chip to work on D4 though, suspect some issue with hidden track on the board but it did work on D5. SD Card can now read and write using CS on D10.

Thanks again.

Notes on this release:

This release includes support for SD cards and System.IO filesystem support.

It includes two new functions in the new SecretLabs.NETMF.IO namespace:
StorageDevice.MountSD(...);
StorageDevice.Unmount(...);

The Unmount() feature is fully implemented. The MountSD() feature currently ignores all parameters except for the PATH varaible. In an upcoming release, we'll be enabling more of the MountSD() function's features.

Hello Chris

I'm trying to use the SD card in the Arduino ETHShield board, see my earlier post at...
http://forums.netdui...write-problems/

Just reading above now I see you say the MountSD() parameters are not yet implemented. I guess this means the chip select isn't working either? (Always defaults to D10 regardless?) I would try jumping D10 to D4 to select my SD card correctly but the W5100 is already on D10.
So, are my assumptions correct? If so any work round or update due.

Many thanks

Stephen
