you are right, but why first time it worked but when i erased all the chip didn't work? when i upload the program at 0x00000000 instead of 0x0001C000, it works (without using SD)

Hi Mamrezo,

the MBR is a part of ourSoftDevices, see this page on Infocenter, thus you just have to flash the SoftDevice to your nRF51822.

Best regards

Bjørn
