SD card I/O error

[mendelbullex]

We have successfully used our SD card to output an audio file on our M54451EVb. WE started working on other things and eventually came back to it without changing the BSp installed. We no longer can use the SD card and get the following message:

mmc0: host does not support reading read-only switch. assuming write-enable.

Does anyone know what the problem is?

[mendelbullex]

Ok, I take it back, the single block read after error is already implemented in the kerenel, therefore, I have no idea what is causing this problema dn would love any feedback that anyone can give me.

Thanks

[mendelbullex · Accepted solution]

Turned out we just needed to reformat the card, completely rebuilding the patitions

[IRTrans]

Hi,

what speeds do you get when reading from the SD card?

We also tested it, however the speed was only about 100KByte/s which made it unusable for us.

An USB stick in comparison is rather fast with around 10MByte/s.

That development board runs the SD cards from the DSPI.

The "lowest common demonimator" speed is 400kHz for "low speed SDIO cards". Other ones should be able to run at up to 25MHz. Check Wikipedia for details on the different speed ratings.

The software you're using may not be switching to a higher clock rate when it could be. It may also not be using the DMA as well as it might.

Thank you for the info.

We are using LINUX - no idea if the LINUX device driver uses the correct clock frequencies.

Marcus

[TomE]

Linux code is most likely to be "lowest common denominator" code.

There's a huge amount of code in the Linux driver stack but you're looking for the "low level platform setup" and the DSPI driver code. You don't have to understand all of it, just "pattern match" with the code that writes the relevant DSPI control registers and find what it is doing. Then try increasing the speed and see what happens.

[mendelbullex]

Ok, so it looks like the error is being caused by a multi block read on the final block when the card is first inserted. It looks like the solution is to do a single block read for the last block. Is there a patch out there that fixes this, or does anyone know how best to add this to the SD driver for linux kernel 2.6.29?
