SDK-v2.0-1703 .

In QorIQ SDK v2.0-1703 Documentation in Table 59. NOR Flash Memory Map is Given .


How to customise this memory map if we want to use root file system with more than 44MB size

Is there any place in the code or compile environment where I have to make the changes for enlarging the rootfs from  0xe9300000  -  0xebefffff  to  0xe8900000 - 0xebefffff .

We have directly connected the msb ( A25 pin ) pin of flash to processor address, LA5 .  Which means we will not have alternate bank concept in our design.

In this case can we enlarge our rootfs from 0xe8900000 to 0xefefffff ..?

Hello k aravind vijaya kumar,

 

If you don't use Hypervisor, you could enlarge rootfs filesystem from 0xe8900000 to 0xebefffff.

Thanks,

Yiping
