This is loop booting. switch didn't responsible to Ctrl Break combination and still try to boot in loop.

How I can get ROMMON menu? No record "press Ctrl C"

 - Try pressing Ctrl-C after the Autobooting... , line.  Your config-register setting is also weird. Check this document :

This is why it's looping. 
Change it to 0x2102.

I can't break loop.

I tried to remove Smart Modular (memory 32) and get ROMMON. With Smart Modular I can't entry to rommon.

I guess some thing wrong with memory, isn't it?

Is it possible to fix memory? Or buy it on eBay?

If Smart Modular is broken, Can I use usb stick or SD cart instead of flash?
