USB Mass Storage device STM32

Indeed an interesting result!

Could you please add a "benchmark" command (*) ? :)

Best Regards, Thorsten.

(*) e.g. generate a 1 MB file. Measure the time how long it takes to write and to read the file. Thereafter copy the file and measure the time again. At the end we will know the read and write performance + the handling performance on copy operations

[philetaylor]

Here is the same MMC+ card using the new "benchmark" function, the copy overhead isn't much at all really..

That is strange, can you try running this version (I have enabled debugging)

I know this really isn't helping you to get a working sd card but it gives me some really interesting debug info :)

It looks like your card doesn't confirm to the SD spec fully.

All of the SD/MMC cards that I have tested, all report csd->RdBlockLen of 9 whereas looking at your previous posts, yours reports 0.

The format routine needs to know how many 512byte sectors can be written at a time and this uses RdBlockLen.

Attached is a quick hack which forces rdblocklen to 9 if it is returned as 0......

This one did the trick!

[strophlex]

But now OS X cant read it... I will format it in Windows now...

[philetaylor]

That's great.

Since I started looking at SDHC/MMC support some months ago, I have discovered that all cards were not created equal :)

I will see if I can find a better solution (as that was a very quick hack).

before you format it in windows, could you just run the "filesys" command please?

I am really sorry... Have already formatted in Windows. It now works perfect in all systems.

If it is of any interest, here is the sdcard response for the card after format in windows:

[philetaylor]

i'm gonna borrow a card reader soon but till then i wonder if this card is trashed?

It is possible that the card is faulty but it is also possible that the size detection algorythm that I am using is wrong :)

I have made various changes to the detection code as it uses the cards CSD (Card Specific Data) to find the size etc of the card. Unfortunately, when I wrote the SDHC (V2.0) detection code I didn't realise that the CSD format had also changed. This is why csd->DeviceSize was reported as 0 in your earlier post.

The CSD should now be correctly reported so could you try the CSD command on mios32_tools now please and post the results?

The problem is that there are at least 3 distinct types of card, SD SDHC and MMC, each one requires special handling and although I do have one of each (which are working fine), different manufacturers seem to interpret the spec differently. Most of mine are SanDisk cards and because they wrote the SD/SDHC spec, hopefully they are the most compliant :)

Cheers

Phil

[philetaylor]

It should be pretty quick (a few seconds)....

This looks like another CSD issue:

[1036683.414] [GET_BLOCK_SIZE] Block Size is 0

This should be (16<<csd.DeviceSizeMul) although for some reason your DeviceSizeMul is 240 and 16<<240 will wrap quite a few times. I would expect DeviceSizeMul to be between 7 and 9 !!!

Leave it with me for a while and I will see what I can do :)

Cheers

Phil

[philetaylor]

Oops, double post (it looked like it had hung!)

Edited March 22, 2010 by philetaylor

[philetaylor]

OK try it now.

I have tried another option which uses: 16 << (csd.DeviceSizeMul>>4) which should be a more reasonable number.

Try the latest svn!

That may be my fault... I inadvertantly left debugging on when I committed my last change. That logs every read and write to MIOS Studio which will "massively" slow the operation down :)

It should be quite a bit quicker now.
