nrf51822 SDK V12 proximity example problem

[Vignesh]

Problem : After successful compilation of ble_proximity example in SDK 12 version Ble is not showing up in Android device How ever If I load pre compile file in example path (/nRF5_SDK_12.2.0_f012efa/examples/ble_peripheral/ble_app_proximity/hex/ble_app_proximity_pca10028_s130.hex) its working I can able to see nordic_proxi in android app

• My environment :
• LInux 64 bit
• openocd
• st link v2
• Waveshare nRF51822 -s130 softdevice

I suspect the problem may be in flashing address , here is my script

• Linker script to configure memory regions. */

SEARCH_DIR(.) GROUP(-lgcc -lc -lnosys)

MEMORY { FLASH (rx) : ORIGIN = 0x1b000, LENGTH = 0x25000 RAM (rwx) : ORIGIN = 0x20001fe8, LENGTH = 0x6018 }

SECTIONS { .fs_data : { PROVIDE(__start_fs_data = .); KEEP((.fs_data)) PROVIDE(__stop_fs_data = .); } > RAM .pwr_mgmt_data : { PROVIDE(__start_pwr_mgmt_data = .); KEEP((.pwr_mgmt_data)) PROVIDE(__stop_pwr_mgmt_data = .); } > RAM } INSERT AFTER .data;

INCLUDE "nrf5x_common.ld"

Finally got the thing working , Only Tweak is in ld script for nrf51822 s130v2 have to you use these

FLASH (rx) : ORIGIN = 0x1b000, LENGTH = 0x25000 RAM (rwx) : ORIGIN = 0x20002800, LENGTH = 0x1800

Thats because the most of the examples (for Nordic's development kit boards) presume the processor if the 32k (QFAC) variant.

Your version sounds like its the QFAA

(Had the same issue myself ages ago)
