RTC problem Keil MCB2300

I had the problem with the RTC on the MCB2300 board, and of course ask google. But I studied about 3 hours and found 50 problems with the RTC, LPC processor, and some solutions that seem to me fairly hooked. Someone solve the problem by changing the capacity of 22pF to 15 pF or vice versa. Someone threw a magic to the processor, someone claimed that the ARM broken. But it passed almost the whole day and my board simply is not working on the external crystal 32 768. But if I switch to the internal clock RTC is working perfectly. Someone even claimed that the oscilloscope can capture RTC oscillations, because of the RTC sensitivity.

My problem was that the oscilloscope see how the X1 line at 400mV and does not oscillate, while the X2 line to 0V. But if you put your finger on the oscillator appears a PWM signal duty cycle 30% at a frequency of some 50 Hz, which sounds a bit illogical. I had a similar problem on PIC24FJ256GB110 processor in which there is a hardware error of the processor that is not written in any documentation. Specifically PIC24FJ256GB110 will not start to oscillate if the X2 line RTC oscillator is not retreat with 2 Mohm resistance to Vcc. Original development board has this strange and confusing illogical resistor.

I tried the ARM board "RTC X2 line" pull with the same resistance but it still did not work. Tried all the examples from the net, each of them thoroughly studied. Thoroughly checked and passed a datasheet for the RTC. But still does not work.
All configuration examples on the net come down to it:

Turn the power!!!
Select the oscillator!!!

But I developed a project with LPC2378 and remembered how I put the crystal on that board. When I tried it on this board, magic, RTC is working perfectly. On the oscilloscope I have a clean 32.768 on the lines X1 and X2. The amplitude is about 2V.

My original Keil board is delivered with a defective "China" crystal.

When I replaced the crystal, everything started to work perfectly on LPC2368 MCB2300. Of course, but it was gone all day...

Here's my function RTC that we work perfectly on LPC2368 and LPC2378 processor, of course, after I replaced the crystal on the MCB2300.
