utFAT / Re: SD Card not formatting

« on: March 26, 2015, 10:11:21 AM »

Hi Mark,
  Thanks for the reply.

I will be back in the office beginning of next week so will be able to test the cards I have.

Regarding the previous SD cards that gave the same problem, I cant remember what the manufacturer is, sorry.

Strange with these cards , I purchased 20 (all same brand) from the same supplier, and probably half worked.

Do you think you can have a fix for these?


Regards
Neil

Hi Mark,
  Just wondering if you had a chance to try it using SPI on the 52259?

Hi Mark,
  Thanks for the explanations. In case you get the same issue with other users, would it be useful if I sent you one of the cards so you can have a look?  The strange thing is quite a few of the cards we got did format okay , and all were purchased at the same time, and same brand.

utFAT / Information from utListDir command

« on: March 09, 2015, 03:24:30 PM »

Hi Mark,
  I was thinking about using the ulListDir command to go through the whole sd card (trailing into directories and collecting files), is there a way to detect after the call if the entry is directory or a file? If so are there any variables that can get the file, or directory  name ?

Thanks
Neil

utFAT / SD Card not formatting

« on: March 09, 2015, 03:15:55 PM »

Hi Mark,
  I am using V2.01 with the processor 52259 , and purchased 20 new 2GB Transcend micro sd cards . When I used (after being formatted on the computer for FAT32) the utFormat or utReformat about 8 of them never formatted. I know my board is ok as I can put a card i know that works in the board. I poll the card with the following command every second.
        if (!(ptrDiskInfo->usDiskFlags & DISK_MOUNTED))
            ...

utFAT / Re: utReadFile/utWriteFile return code

« on: January 08, 2015, 03:59:13 PM »

Hi Mark,
  Thanks for the reply. 

If UTFAT_SUCCESS is not returned , is there any problems then reading the ptr_utFile->usLastReadWriteLength value then do a Seek(..) , only if its not zero, with the UTFAT_SEEK_CUR option , just to make sure the position is in the same place as before the read/write? 
Is ptr_utFile->usLastReadWriteLength always set to a value , regardless if UTFAT_SUCCESS is returned or not?

utFAT / utReadFile/utWriteFile return code

« on: January 08, 2015, 05:31:22 AM »

Hi Mark,
  if a utReadFile(..) command doesnt return UTFAT_SUCCESS, can I assume that no data was read, and the file position hasnt moved, so another read would continue from the same position within the file? The same with utWriteFile, if it doesnt return UTFAT_SUCCESS , can I assume no data was written and the file position hasnt changed, so another attempt will continue from the same place?

I ask the above, as mentioned in a previous post, there is a possibility that the SD cards internal processor may be busy when a request is made, thus preventing the command to return success.

Best Regards
Neil

utFAT / MANAGED_FILES

« on: November 14, 2014, 06:29:32 PM »

Hi Mark,
  I have just upgraded to the latest uFat and noticed MANAGED_FILES isnt defined , but see UTFAT_MANAGED_MODE defined as #10 in the .h file.  Does this mean I havent been using managed mode?

Do I have to #define MANAGED_FILES too?  If so, what is the value after it represent?


What is the difference between MANAGED_FILES/MANAGED_FILE_COUNT  and UTMANAGED_FILE_COUNT ?

Thanks
