F.A.Q Of Mp3/Mp4 Players..//

F.A.Q About Mp3 & Mp4 Players... All information you want to learn about Mp3 / Mp4 players 1. Using your player Q1: Is there a firmware update for my player First: If your player works, keep it that way : don't update!! "Updates" don't exist for the players, there are just a lot of different versions of the same firmware. But not all versions work with all boards. Each firmware is made especially for one board type, so if you update your player with a wrong version, it dies! Q2: The player has less memory than normal, and restarts displaying "format error", "I/O error" or "disk error" when I upload more than 128/256/512/etc MB, OR it always reestart after playing song X. What you can do is to format the player using the tool that came on the the latest version of the "MP3 Player Utilities", available in MP3 Player Utilities. Do a complete format and don't set any encripted drive. f this does not help, try the "disk management", reached at "Control Panel -> Administrative tools -> computer management". Right click the mp3 player partition, choose "format". Use "FAT" or "FAT16" (NOT FAT32!) If it does not work, you can try a low-level format using this tool :HP formatting tool This is a known problem. It is some bug in the firmware If formatting does not help, you should check if the memory chip inside you player has the capacity that the players claims. Q3: My device is at "ADFU server" mode and I can't acess it using windows... This means that your player is at the the recovery mode. You should now pick a firmware for your player and flash it. For more help, see our dead device recovery guide: Find the apropriate firmware for your mp3 player. Q4: Can the s1mp3 can recharge the battery while it is connected to pc? If you player has an internal recharcheable battery, it will include a special internal circuit to do that. If your player does not have this circuit, you best recharge your batteries on proper chargers to avoid acidents. However, there is a article that explains how to make a simple circuit to drive power to the battteries. Q5: I can't get my telbook function to work! Read the Creating and viewing the phone book. Q6: How can i get my lyrics function to work? See How To set up lyrics. There is also a nice freeware program out there that can help you with it. It also has a Tutorial Q7: The LED colors keep changing every time I press a button! How can I stop it? On "System" menu, change the "backlight mode" option Q8: I can't play all the songs I put on my player(only the first 99), what can I do? The player's firmware is limited to 99 files per folder. Q10: how can i change the order that the s1mp3 plays the songs? See how to set the playing order at Using the S1MP3 as an MP3 player. Q11: I can't open text files? why? See Creating and viewing the text files. Q12: What is the difference between actions s1mp3 players (with atj2085 or atj 2075), and the sigmatel STMP35xx? Not very much, in the way that they both play music. Sigmatel claims that the atj2075 and 2085 are copies of their SMTP25xx series, and has even filed a lawsuit against them! Apart from the different looks, they have totally incompatible firmwares, and (some of) the sigmatel players have a slot for an extra Secure Digital flashcard. Q13: When playing songs (sometimes/always) there is a low "buzzing" sound in the background of the song. This has only one explanation: interference. The s1mp3 player is quite cheap hardware, so it is not shielded from interference very well. In fact, it even creates it's own interference. In some hardware versions, severeral of the memory data lines run along the audio lines, so everytime the memory is read or written, there will be interference from the memory with the audio. This also explains the absence of interference during radio playback (as reported sometimes): the memory isn't really used then, so there is no interference. There is, althought, a way to fix that problem , it appears to be due to a decoupling tantalum capacitor not being big enough. The capacitor is on the battery side of the board and is between the hold switch and the -ve volume button. I found that soldering another surface mount 68uF tantalum across it fixed the burbling noise on memory playback. try holding a largeish (220uF) electrolytic against this capacitor's leads to see if it cures the problem , itmay cause reboots due to static/whatever, but when it doesnt cause a reboot it may/should reduce the noise, if it does then try soldering in a permanent fix.
