Bootloader issue when using CustomBoard

[Brook Gebremedhin]

hello,

I have a custom board which works fine with SoftDevice+Application , but if i Combine a boot loader hex that i complied it doesn't work. But the same ( bootloader+application+softdevice ) works fine in the board pca10028.

my custom board works fine when i use a precompiled hex file that i found online www.dropbox.com/.../sd_boot.hex from the forum developer.mbed.org/.../

But i want to use bootloader hex that i compiled by my self. as i said the boot loader hex file i compiled my self works on my board pc10028 but not in my CustomBoard.

I have tried to changed to different clock source but that didn't help. my application is using S110 sofdevice v 7.1.0

my Custom board don't have an external Oscillator , also no button . It is a small chip which uses internal Oscillator.
