Help!!! Sd adapter!!!

edited 2009-09-27 23:29 in Propeller 1
I made an sd card adapter but it does not work!· I have tried both femtobasic and propdos on it and it doesn't work...· I have a "Card Inserted" LED that has the cathode connected to the (-) supply and the anode is connected to the pins on the SD card that are for ground.

The wierd thing is, the LED is on for a second when the demo board is turned on, but once the program gets to the point where it's trying to connect to the SD card, the LED goes off.

Why?!?!?!?· cry.gif


Thanks.

    Well, I had something like that when I tried to run an SD card at 5V... I didn't like it...

    Better check your card on a PC and see if it still works!

    Yes, it still works. I had accidentally plugged it into 5v on the demoboard for about 15 seconds, then yelled and quickly removed the power. I promptly inserted it into a laptop with a reader and--it worked.

    One thing--Do I need to have files on the SD card in order for FemtoBasic or PropDOS to work...? I don't have a single file on it, so....


    Thanks.

    No, but it needs to be formatted.

    Read the contents of

    thoroughly and let me know if you still have questions.

    If a power led is going out, then you probably have one of the pins touching ground where it shouldn't...

    Quick question-- I can't seem to find anything that has an option for cluster size... When I right click on the card in My Computer, I selected Format... and then selected FAT then hit Start. It came up with a warning saying This will erase all previous data. Do you wish to continue? or something along those lines... So far, no harm done.


    I don't know if I did it right... I will check if it works now and get back to you.

    I was pretty sure I did it correctly, but I will check....

    Also, I just went to cmd prompt and I think I got it formatted into FAT16 with 32k in each allocation unit...

    I will keep you all posted on everything. smile.gif

    Vaati,

    On my last board, I had some issues with the SD checking routine not
    seeing the SD card on bootup and reporting an error. These routines
    are in both Femtobasic and Propdos. I switched them out with a
    "reboot" when the error was detected and bypassed the issue.
    It seems that the card isn't startup up as fast as the rest of the
    project, and given a reboot it seems to catch up the 2nd time around.


    I haven't had time to debug the board with all the expo stuff going on.

    Oh....
    I think I know...

    I got a Kingston 2GB *Elite Pro*

    It said in the description that it has faster data transfer and such... My dad thinks it's autoformatted or something and that it can't be changed, so it's impossible to use....



    Lucky me... Now that I get something that isn't faulty, I can't use it!

    OBC, how do I reboot it...? In femtoBasic, I start getting p.o.-ed at the entire "Syntx error. OK" No, it's not okay!! And for PropDOS, it just aborts the operation....


    The weirdest thing is.... the SD ccard worked the first time I tried to work it on my demented breakout board setup....

    In that section that says "No, it's not okay" I put a "reboot" command.

    I found a reboot command in PropDOS, but I can't seem to find one in Femto...


    I'm trying my adapter with all my props now. First is my Gadget Gangster Boss Board, then my two prop protos. One more quesiton--is there a program for the Basic Stamp 2 that lets it acces SD...? That would be a nice way to test it...


    Thanks.

    Step 1:· Remove LED

    Step 2:· Check this page for proper wiring:

    Hmmm... Couldn't I just override the LED by skipping it and sticking a wire to the negative on the board itself, so then it doesn't have to go thru the LED?


    I will check the circuit now.

    Okay, I checked that site... the only difference is that I used 10k pullups instead of 20k. Also, I really don't understand EXACTLY how to format my sd card to fat16... could someone tell me how to do that using a 2gb card and formatting it with cmd prompt...?


    Thanks.

    Okay, well it didn't let me do exactly 32,768 but it worked with 32k. Here's what it said after I formatted it:

    Format complete.

    1,966,768,128 bytes total disk space.
    1,966,768,128 bytes available on disk.

    32,768 bytes in each allocation unit.
    60,021 allocation unita available on disk.

    16 bits in each FAT entry.

    Volume serial number is 9C8B-373C


    What in the world does all of that mean???




    Thanks.

    Looks good!

    "32,768 bytes in an allocation unit" means that the smallest file
    will be at least 32,768 bytes. No big deal for what we are doing.

    But.... It still doesn't work!! I have tried PropDOS with it after the formatting and nothing happens! It just says that the SD card cannot be found or whatever.... I have it connected to the right pins and all....

    Also, I know it isn't the prop itself, because I tried it on my dip as well...



    Gwahh....

    You might take another look at the photo of the SD card on my site (that has the pin#s written on it)... Your diagram has the pin numbers all in sequence, but that's not how it really is...

    no i ment for the prop one like the one sold at ucontroler.com or a propmod-un_sd which has the reader built in. good to test with something you did not build when the one you built is not working.

    Well, I know that, but I chacked the site and for my diagram, I just labeled the pins on the slot itself from left to right with the slot right side up..... I do know that the pins on the card are different, but if you compare the card to the SD slot, you will find that it is correct....

    no. just a sugestion for a way of checking things. if you buy something you know works with the prop and it does not work then it is the code or prop at fault. if it works then it is the hardware at fault.

    you can also upload very high res photos and copies of exact code and somone may find problem.
