If the application you're building in the Arduino IDE is compiled against the headers of the S132 v1.0.0, then you should not have any issues. Please verify that the application is compile with the correct headers.

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)

Then your program obviously don't use SD (and don't need it;).

Does your application use Bluetooth Low Energy to communicate with other devices?

[mamrezo]

no it is a simple blink program
