TQ 2440 board
Posted: Tue Sep 08, 2009 7:32 am
Hello,
I'm working actually on a S3C2440 board (Development board with core board). This board is neither a Mini2440 neither à QQ2440. It's a development board featuring an extractable core board. The only reference on the base board is "2440_BOARD", no reference on the core board.
I think the board is TQ2440, but all documents on the internet are in chinese.
I've a few question about this board :
1) When I move my hand close to the board, it simulates a press on "right cursor". After examining the schematic I found that the EINT17 (GPG10) pin is connected nowhere. Does this pin is responsible of this behaviour or is it the base board?
2) Which BSP Should I use ? Mini 2440 or QQ2440 BSP ? Or is there a special BSP for TQ2440? I've examined the pinout of the processor on TQ2440 and Mini2440 and found some difference (adress bus, GPIO, USB_EN etc...) didn't look at QQ2440 schematic.
3) General question about WinCE : I've also a Mini2440 board with 64MB RAM(the TQ2440 also has 64MB RAM) when I look at System properties in WinCE I see only 32 MB. Those this affect the programs? is all the 64 MB RAM available for programs (WinCE surely use a bit) ?Those this come from a configured BSP to be compatible with 32MB versions? Is it a configuration option in the BSP ? How can I fix this?
