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
nrfjprog --program _build/nrf51822_xxab.hex -f nrf51 --sectorerase
Parsing hex file.
ERROR: The file specified is not a valid hex file, has data outside valid areas
ERROR: or does not have data in valid areas.
Makefile:250: recipe for target 'flash' failed
make: *** [flash] Error 52

Keil + nRFgo Studio (after Program SoftDevice)

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

Thanks in advance!

Thanks again, Bui.

I've changed the configs to match the initial project configuration:

IROM: START= 0x1B000, SIZE = 0x20000 IRAM: START = 0x20003440, SIZE = 0x4BC0

Now when I try to program the application the error says "The flash is not erased."

The Keil build outputs the following:

Program Size: Code=32844 RO-data=2152 RW-data=412 ZI-data=5996

That means that I need 32kB of flash free for the application? If true, what can I do to reduce the "Program Size"?
