For example when I want to boot p4080ds from nor flash bank 1, I need to set SW 7[0100XXXX] then load RCW and uboot. Basically I want to using direct addressing not related addressing which means when I want to&nbsp; boot p4080ds from nor flash bank 1, I do not need to change SW 7 from [0000XXXX] to [0100XXXX]. Is this possible?</P><P>Best regards.</P></BODY></HTML> Wed, 15 Jun 2016 07:01:18 GMT yyurtcan 2016-06-15T07:01:18Z P4080DS NOR FLASH RELATIVE ADRESSING https://community.nxp.com/t5/P-Series/P4080DS-NOR-FLASH-RELATIVE-ADRESSING/m-p/521076#M3320 <HTML><HEAD></HEAD><BODY><P>Hi,</P><P>I have question about nor flash relative adressing.

The Flash address inputs A23–A25 are not connected to the P4080 local bus addresses A7-A5 directly on the P4080DS. The “address toggle” feature by SW7 is implemented by multistaged XOR gate which adds ngPIXIS signals defined by SW7 and P4080’s A7-A5. See details in section “Local bus” of the P4080 Development System User’s Guide. </P><P></P><P>-----------------------------------------------------------------------------------------------------------------------<BR />Note: If this post answers your question, please click the Correct Answer button.
