ADZS-BF609-EZBRD is used for evaluation with EVAL-WVGALCD-EX3 and it work's ok.

NEC NL6448BC18-01F LCD Display Linux Driver for ADZS-BF609-EZBRD


We make our custom board based on EZ-BOARD and try to run display on it. Although we connected display similar to EZ-BOARD on PPI2 port it doesn't work.

Of course we don't copy SoftConfig switches because it is totally senseless but it seems that the problem is SoftConfig.


When I comment line "soft_switch_config();" at line 477 of bf609-nl8048.c file the reference display connected to EZ-BOARD stop working too. And we even can not see any signals on PPI2 (clk, hsync...). It's totally silent.


Is there a connection between SoftConfig initialization and absence of signals on processor pins? Not after switch, right on processor.


If you need more information please let me know.
