SanDisk Sansa c200v2, m200v4, clipv1, clipv2, clip+, and fuzev2

Did you find anything that should be fixed in SVN regardless of the clocks? It looks like we should look into using the fifo for example.

[FlynDice]

I don't think SVN needs to be changed until we figure out how to use the FIFO if that is indeed the problem.  Current SVN actually works quite well from a typical user point of view.  We can playback from either card just fine, we just know that the cards are overclocked and we can't write reliably to the uSD.  I bet 80 % of users would never notice themselves without being told...

I copied over files to my microSD card several times already, and I've never had any problems with it. It's a SanDisk 8GB Class 2 card.

@yelped:

Which player?

[yelped]

Fuze v1.

[FlynDice]

Could I get some results from both fuzev1 and e280v2 with current svn copying a file from internal sd to microsd.  Please identify the make, class and size of the microsd also.

I'd like to figure out if this is a card related issue, or an e280v2 only issue.

r22814 Fuzev1

internal -> µSD = SD transfer error : 0x2 (DATA CRC FAIL)
µSD -> internal = OK

r.22077M - e250v2
& r. 22819 because i thought my revision was a bit old

Thanks guys.

I'm assuming this is a problem with certain cards then and not players...

I have an 8GB Transcend class 6 µSDHC & get CRC failures similar to funman.

Sounds like the Sandisk class 2's work just fine.

Now can I get some results for Sandisk class 4 & 6  and non Sandisk any classes that don't work.

I'm wondering if this is a class 6 problem or perhaps Transcend.

All the builds I've tried and the latest 22819

internal -> µSD = SD transfer error : 0x2
µSD -> internal = OK
Silicon Power SDHC 8gb class 6
Transcend 8gb SDHC class 6

r.22077M - e250v2

internal -> µSD = OK
µSD -> internal = OK

SanDisk µSDHC 8GB Class 2

Same here with r22820.

[yelped]

I tried again with my Fuze and 8GB SanDisk microSDHC Class 2 card, both ways, several files, and no problem. Thank G-d!

[FlynDice]

I added a delay to writes to the microSD and my class 6 card works fine now.  Does yours....?
