Assuming switch1 and switch2 are normal ethernet switches, you need a
crossover cable connecting switches 1 and 2 (Tx of switch 1 -> Rx of
switch 2 and vice versa) unless your switch PHYs support auto-crossover.
You need CPU1 to run TFTP server software. The it should Just
Work[tm], no VPN or VLAN.
On the other hand, your hardware may not be normal ethernet switches, in
which case we have even less of a clue than you.
