I`m new to Linux and ARM9 (not ARM7)
sorry if this is a silly question.
AT91SAM9260`s maximum frequency is 200-210 MHZ,
will this be sufficient for running a QT Application with Touch Screen?
or should i use AT91SAM9G20 upto 400MHZ.
what is the minimum requirement for a QT Application with Touch Screen?
Minimum requirement of the following things
1.CPU Power
2.RAM
3.ROM
AT91SAM9260 and QT

200 MHZ is ok, 300 MHZ is ideal and 400 MHZ is better. These are *very*
subjective definitions, someone else may find 200 MHZ unacceptable. In the
end, Qt can work with 200 MHZ.

Minimum is 32 MB.
At least I know that it is working with 32MB and I don't think 16 MB is enough
for running a full featured build of Qt.

Installing all Qt components(Gui, Network, Webkit, etc) can consume ~60 MB on
a compressed file system(with Glibc).
More important factor you didn't ask is screen resolution. I don't know 9G20
but AFAIR 9261 is using system bus for LCD whereas 9263 is using a seperate
bus. So 9263 is better when it comes to GUI applications. If you are after a
QVGA resolution it should be fine, for higher you need to check some
documents.
