nRF5 SDK 12.3.0 Eddystone on nRF51822 beacon

[Abraão]

Hi,

I've seen that SDK 12.3.0 contains a new version of the application sample using the Eddystone protocol for BLE. I would like to know if this version is compatible with nRF51 chips as it was said in GitHub:

Experimental support for nRF51 is found in nRF5 SDK Version 12.2.0 A future 12.x release will add production quality support for nRF51 for Eddystone.

I tried to program a beacon with nRF51822 chip using the SDK example (nRF5_SDK_12.3.0_d7731ad\examples\ble_peripheral\ble_app_eddystone), but I did not succeed.

GCC (after make flash_softdevice)

nRF5_SDK_12.3.0_d7731ad\examples\ble_peripheral\ble_app_eddystone\pca10028\s130\armgcc>make flash
Flashing: _build/nrf51822_xxab.hex

Keil + nRFgo Studio (after Program SoftDevice)

Could you guys help me identify the cause of the errors above?

Thanks in advance!

Thanks for your reply, Bui.

Yes, I did the flash with S130 (s130_nrf51_2.0.1_softdevice.hex) before trying to program with the Eddystone example.

On GCC I've used the "make flash_softdevice" instruction:

On nRFgo Studio I've used the Program SoftDevice tab.

These are the configs of IROM and IRAM:

GCC (ble_app_eddystone_gcc_nrf51.ld)

MEMORY { FLASH (rx) : ORIGIN = 0x1b000, LENGTH = 0x25000 RAM (rwx) : ORIGIN = 0x20003440, LENGTH = 0x4bc0 }

Keil (default values when you select nRF51822_xxAB device on Keil)

IROM: START= 0x0, SIZE = 0x20000 IRAM: START = 0x20000000, SIZE = 0x4000
