Wrong EPCS controller span

Hi All,

I'm using EPCS128 and having a problem with defining it's controller in Qsys / SOPC.

When adding the EPCS controller, there is no place to insert the size of the Flash.

The span that was automatically set is 0x800. :huh:

How can I tell Qsys that I'm using 128Mbit Flash??

Thanks,

Yan G

    This 0x800 span only includes epcs controller registers and bootloader code.

    Actual flash memory is indirectly accessed by HAL drivers through these registers.

    Thanks Cris.

    I missed that on-chip memory for bootloader part...
