I noticed in the file PXL.Boards.RPi.pas the following note: // The following option controls whether the code is optimized for Raspberry PI 2. {.$DEFINE RPi2} And further down I found that this define controls the address used for GPIO: FChipOffsetBase := {$IFDEF RPi2} $3F000 {$ELSE} $20000 {$ENDIF}; // in pages (x 4096 bytes) So it looks like it is going to solve my I/O control on the Pi2! Now I just have to figure which files to copy over to the Pi for this to work, the complete download is very big and most of it I really do not need... -- Bo Berglund Developer in Sweden -- _______________________________________________ Lazarus mailing list [email protected] http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
