Can't access CompactFlash via FTP on cFP-2220 with RT 8.6.1

[Jesse_D]

Hi dfousek, 

Although the device only supports up to 512mb flash officially, per the manual, it may work with more as we are both aware. NI doesn't test or support more than 512mb (see here). I am happy to help you with trouble shooting steps but I cannot promise I will be able to escalate this to R&D if we cannot fix it. 

I think the real problem, seeing how compact flash is extremely cheap, is determining whether your system is having problems with larger flash cards. My first guess, judging from the fact that I could find no one else who is having this problem with 2011, is that it might be an issue specific to Kingston drives. Do you have another flash card you can try? 

You also might look to see if there are RT system errors when running 2011:

Hello, guys.

I've had similar problem too. But I've read the whole post and found the solution.

Capitalising the 😧 worked for me just fine.

Can't thank you enough!

Back to the playground.

Best of luck.

Hello all ( especially Jesse & Deborah ! ),

No, my case is not solved with the capital 😧 letter.

After several tries, now I know that, upgrading LV RT 8.5.1 to LV RT 2011 (following exactly the recommended procedure) causes a 'loss' of the CFlash drive (D:). Then, if downgrading back to LV RT 8.5.1 the ftp to 😧 works fine (the CFlash remains the same and not removed).

This is reproduced to 2 cFP-2120. Also, it makes no difference if the upgrade goes to LV RT 2011 or LV RT 2010.1.

The CFlash that Itried are Kingston (4GB), Sadisk  (4GB), Transcend (256MB industrial) formatted to FAT32 (4kb alloc unit size) or even FAT.

The only case when everything works fine is when I insert a tiny 8MB (FAT) Canon card. In that case, when upgrading an ftp to 😧 works fine.

Now, if somebody from the NI Labs could sent me an LV RT 2011 image, that would be the ultimate test.

Is this possible ?

Regards,

Dimitri

Happy to do so. I made an image of a 2120 with 256mb flash which is working properly (side note, I can access the drive as d: or D). It should be on our file transfer site as 2120Flash.zip.

Jesse, I cannot find the file. Please, check whether it is really located in the 'outgoing' directory....

Thanks,

Dimitri

dfousek,

I just reposted it. Things only stay in that directory for 48 hours.I would attach it directly but it is too large for the forums.

Let me know if you still can't find it. We have one other customer having a similar issue, we are working with hiim directly, thanks for your patience and we will be sure to keep you posted on what we find.

Hi Jesse !

Nothing changed with the image you sent me. ... In fact, running just the NI-MAX reveals the problem:

I get a cFP-2120 (bios 10.4) and connect it to a PC running NI-MAX, with versions 6.08 (fieldpoint) and 8.5.1 (RT LV). I select 'Format Disk'. Then, in the 'Add/Remove' software, I install the (minimal) version. Finally, I go to NI-MAX's 'File Transfer' and there I can see the contents of all my CFlash cards (5 brands, FAT32 or FAT formatted).

If I repeat the procedure using NI-MAX with 6.09 (fieldpoint) and 2011 (RT LV) everything is fine except the fact that I can only see the root directory of the cFP-2120 and not the CFlash (either d: or D:).

The same happens also with the 3rd pair: 6.08 (fieldpoint) and 2010 (RT LV). As I have posted before, I can reproduce this with another module cFP-2120.

Consequently, I can find only one reason that the same module access a CFlash card using  6.08 (FP) and 8.5.1 (RT LV) and not with the last LV versions: Something has changed within the software responsible for the CFlash access. I guess that the FieldPoint driver is not guilty (6.08 works) and the problem resides to LabView. Don't you agree ?

Any further help will be really apreciated !

Kind regards,

Dimitri

Hi dfousek,

I went and got a dozen different flash cards, let me see if I can reproduce the problem.

[Jesse_D]

Good morning dfousek, 

I was able to detect all the flash cards in both 8.5 and 2011.

I think that this may be a driver issue. I am running FieldPoint 6.0.9, which could fix your problem. If there are any known issues with 6.0.9, which I couldn't find, they will be fixed by getting the latest driver version. 

You can just install the latest device drivers here, which will update your entire system. 

It ended up with another customer that the given flash architecture just didn't work in a later version of labVIEW, switching flash cards solved the problem. Also, you may want to double check your cards are formatted to FAT32. 

Here are the architectures I tested on 8.5 and 2011:

Worked: 

Sandisk 32MB

Kingston 245MB

All NI Cards 

NetList cards

SimpleTech 128MB

Did NOT Work: 

SQF-P10S2-4G-ETE

Delkin eFilm Industrial 

This KB may be helpful for you, our cards are based on NetList cards.

I don't have more third party 4GB cards on hand, but it seems like this is just a flash card issue. Has the situation changed on your side? 

[dfousek]

Hi Jesse !

No, nothing changed from my side.. Thanks, for your input. Just a clarification: Those 2 CFlash you mentionned that did not work, were they 'visible' (through FTP) by 8.5 RT ?

Otherwise, I believe that no matter the version of FP (6.0.9 or 6.0.8), what it counts is the Labview RT edition.

Regards,

Dimitri
