Programming nRF51822 using SWD

I am able to flash the BLE SDK on nrf51 Soc in Linux environment using openocd by below command.

openocd -c "set WORKAREASIZE 0;" -f /usr/share/openocd/scripts/interface/ftdi/SWD_FT.cfg -f /usr/share/openocd/scripts/target/nrf51.cfg -c "init; reset halt; program <<path of your file>> 0X0 verify; shutdown;"

Now I am looking to flash BLE application on different flash address but not sure how to proceed with openocd. Anyone have idea regarding the same.

You can use IDAP-Link with a simple command to flash all 3 parts without needing mergehex.

IDAPnRFProg s110_nrf51_8.0.0_softdevice.hex Blinky_ble.hex dfu_nrf51.hex

It also works with OpenOCD, Keil, Crossworks, etc. Full CMSIS-DAP with Drag & Drop feature

I use Eclipse with GCC, GDB and OpenOCD to program the nrf51 using the ST-Link/V2.

To flash the SoftDevice using OpenOCD and any compatible Jtag (tested with ST-Link/V2), you can do:

$ openocd -f interface/stlink-v2.cfg -c "transport select hla_swd; set WORKAREASIZE 0x4000;" -f target/nrf51.cfg -c "init ; reset halt ; nrf51 mass_erase ; sleep 500 ; flash write_image .bin 0x0 ; verify_image .bin 0x0 ; mww 0x4001e504 1 ; mww 0x10001000 $(STARTADDRESS) ; mww 0x4001e504 0 ; shutdown"

The application start address depends on the SoftDevice you use. The address value is given in the SoftDevice release notes (0x16000 for s110 v. 7.3.0 for instance). Do not forget to change your linker script with this offset value.

Have a look at this Makefile to see other targets to program your application or to erase the flash.

I use jlink at last .

I can program via OpenOCD trunk. Also could program softdevice by hand using by downloading binary to correct addresses.

 openocd -f interface/stlink-v2.cfg   -f target/nrf51_stlink.tcl -c "program <path_of_the_bin> <address>"
