Hi,
if you just want to configure which bank to use with pflash, perhaps you
can do something like:
qemu -drive if=pflash,unit=0
to use the first bank, and
qemu -drive if=pflash,unit=1
to use the second bank.
Yes, that might work for the flash case but does not address other
switches settings. In my case, the Mainstone has two rotary switches
that define which frequency to boot up in.
But I don't think qemu able to emulate frequency ?
So it should be useless.
I am sure that is true and my example might be very week in the above case.
I think if a board we are trying to emulate has boot time configurations
governed by jumpers or switches for enabling or disabling certain
hardware devices , then having a runtime solution seems more
appropriate. It seems silly to have to rebuild to qemu if one wants to
switch device A to be uart #2 from an IrdA device when using "-switches
1=on" could do the same.
Well, my opinion is not really important here, but I think "-switches
1=on" is too low level... using the "meaning" could be more
user-friendly, something like "-deviceA uart2".
