BBL SD Card Error Work Around

[swingtan]

Hi All,

Checking the forum and from my own experience, there seems to be a bit of trouble at times with SD cards being accessed when in the V2. I've done a bit of testing and think I have a workaround for the issue.

Description

When inserting an SD card into the V2, the indicator shows the memory type changing from "IM" (Internal flash Memory) to "SD" (Secure Digital memory). this leads you to believe that the V2 has correctly identified and initalised the SD card reader and is ready to use it for storing data.

As soon as you attempt any write action to the SD card, you get one of the following errors...

• Error: $0183: Invalid Folder.
• Error: $0185: File or Folder not found.

I can get the $0185 error simply by doing the following....

1. V2 is connected to vehicle and has just been used to save a BBL file to the SD card.
2. Remove the SD card from the V2.
3. Insert the SD card into the V2.
4. Wait 5-10 seconds.
5. Press the V2 "Power" button to start a new log.
6. The V2 displays "Creating Log File"
7. The V2 then displays "Error: $0185 File or Folder not found."

Subsequent attempts to start a BBL log file are met with the same error and the SD card works fine in any card reader.

The Work Around

I have tried many, many different ways to get the SD card to be more reliable. At one time I found that using a very small sized SD card ( 32Mb ) was nearly always successful, but using my 2GB card resulted in a very low success rate. I did notice though, that once you got the card to start working, it was 100% successful at storing data until the next time it was removed from the V2.

This led me to believe that there was something funny occurring in the initial access and setup of the SD card in the V2. So I figured there must be some way to "force" a "re-check" of the SD card parameters. So I tried checking the SD card statistics via the V2 menu. From the home menu, pressing

[F4]-[F2]-[F1]

will display the SD card parameters, and it appears that it checks these at the time of the request. Once this operation has been done, I had 100% success with accessing the SD card in the V2.

The Reason???

While I can't be certain, I think there is a timing issue in the V2 that causes a misread of the SD card parameters when the card is first inserted. Once this has happened, the V2 cannot correctly access the SD card, as the parameters it is using are incorrect for the card. I'm guessing it's a little like getting the Heads/Cylinders/Sectors parameters wrong when setting up a HDD ( older PC users may remember having to do this step.... ). While the overall size of the drive might be correct, you couldn't read any data unless these settings were matched to what was on the drive.

Rechecking the SD card parameters via [F4]-[F2]-[F1], allows the V2 to "re-discover" the correct SD card parameters and it now sees the correct directory structure on the SD card.

Cool bananas. Have to give that a shot and see if i get the same results.

Have a good weekend!

When was the last time you formatted the SD card?

Good error report...

[swingtan]

mr.prick: The card was formatted in the V2 a few days ago, as part of the latest update. As mentioned, it will nearly always fail after the initial insertion, but will always work after the SD parameter check.

Good to know, Ill make sure I do this every time I reinsert the SD card.

Wonder if we can bug the higher-ups to implement this key press when a SD card is inserted.

I would say it already does this automatically, but I think with the bigger sized SD cards, there may be a timing issue where the card is probed too soon? Maybe if the SD card probe was delayed by 500mS it would work better.

Good idea, might make it more stable for all card. Ive had this issue with a 128mb card, havent tried anything bigger as I dont need to and have a 16mb and a 128mb card laying around.

Hi All, I faced the very same problem today (First use of V2). I did read all the threads about this error ($0183) and tried all the recommendations here and there but no luck

However, I tried to format the SD card from my PC (XP) then inserted the SD into V2. Tried again using EFILIVE L Explorer and it worked and the error is gone. Now I can copy and paste option.txt & .pmm files using EFILIVE Explorer to V2

Didn't log anything yet as I was trying to find a solution for this error. I will try to keep you updated.

Thanks

Scan tool -> select PIDs
Here is screen shot (attached) after copying option.txt, *.pmm & *.dtc files to V2

I hope I won't get more errors while trying to log from the vehicle
