nRF51822 not detected by nRF Connect

[Sergio]

Hi,

I'm trying to program a nRF51822 board following this tutorial (chisight.wordpress.com/.../) using OpenOCD in a Raspberry PI.

I have been able to burn the compilated ble_app_proximity example code (in .hex format) that the SDK contains, and in that case the nRF51822 is detected correctly by the nRF Connect iOS app. However, if I compile the main.c code contained in the same example of the SDK with Segger Embedded Studio, and I burn the .hex output in the same way that I did before, the burn is successful, but nothing is detected by the nRF Connect iOS app.

I'm using the following section placement macros:

FLASH_START=0x1C000 FLASH_SIZE=0x24000 SRAM_START=0x20000000 SRAM_SIZE=0x1800

Thanks in advance !

I'm using S130 v2.0.0, and the nRF51822 16 kB variant. However, if I compile with the SRAM_SIZE configured to 0x1F80 I get a RAM overflowed error, and if I compile with the SRAM_SIZE configured to 0x5F80 nothing happens when I burn the code. If I burn the compilated file contained in the SDK, it works perfect. I've tried using gcc instead of Segger but the result is the same. Could it be the flash address?
