Re: [microblaze-uclinux]How to config Petalinux to surport two banks of FLASH memory ?

[Childhood Hwang <childhood.hwang@xxxxxxxxx>]

Hi John:

    Thanks a lot :) .

    I add codes like the attached in physmap-flash.c several months
ago, but the 2nd flash doese not work at all.
    I also add kernel command line like this:

mtdparts=physmap-flash.0:8M(fpga),256K(boot),128K(bootenv),128K(config),5M(image),18M(spare);physmap-flash.1:32M(flash2fs)

    So I think I have done the right thing of kernel configurations, I
should check my hardware more carefully.

Rgs.
Childhood.
