I have 3 devices connected to the eLBC bus which are - NOR Flash, FPGA and a NVRAM.&nbsp;&nbsp; The NOR Flash is the boot device and is connected to the GPCM mode.</P><P></P><P>1.Can I connect all the three devices in the GPCM mode. Will it have any effect or will it create any problems while booting from NOR Flash.</P><P></P><P>2.Are there any limitations to connecting these three devices in the GPCM mode of the eLBC bus.</P><P></P><P>3.What mode of operation would be better for the FPGA and NVRAM - GPCM mode or UPM mode ?</P><P></P><P>How does one choose which mode needs to be used?</P></BODY></HTML> Wed, 19 Jul 2017 11:20:35 GMT https://community.nxp.com/t5/P-Series/Mode-configuration-in-eLBC-for-P1015/m-p/675867#M4098 pavankumarg 2017-07-19T11:20:35Z Re: Mode configuration in eLBC for P1015 https://community.nxp.com/t5/P-Series/Mode-configuration-in-eLBC-for-P1015/m-p/675868#M4099 <HTML><HEAD></HEAD><BODY><P>1.
