Cannot find bluetooth-device in 51822QFAA

[yuyixuantai]

Before I use 51822QFAC(with 32K RAM)， add I must use 51822QFAA(with 16K RAM)。 

I have modify IRAM area，like this

IRAM: 0x20001FE8  0x2018.

and selete device is 51822QFAA  in keil/porject/option/device.

now my code  can run ok in 51822QFAC, but cannot run ok in  51822QFAA;

In 51822QFAA I cannot connect it with my phone（It could be connect with the same code in 51822QFAC). Now  I sure ram area is in safe-area（0x20001FE8-0x20003FFF）。Code can debug，can shine leds, can check buttons. 

I donnot know the reason.

My softdeice is S130. Is softdevice not support  51822QFAA? Or do I make orther mistake?

The board with the nRF51822QFAA chip, is that a custom board? 

If so, could you verify that the LFCLK clock source set  in the application code matches LFCLK clock source available on your board? The examples in the SDK does for example use the LF crystal by default.
