This link solved my own issue.

step 1: git clone git://git.code.sf.net/p/openocd/code openocd-code

step 2: cd openocd-code

step 3: git pull openocd.zylin.com/openocd refs/changes/15/3215/2

setp 4: After this we have three conflicting files that have changes that we must deal manually.

4.1 Replace src/flash/nor/drivers.c with file on this link https://pastebin.com/5X4e9QC2

And remove or comment line no. 49,50,54,55,105,106,110,111

4.2 Replace src/flash/nor/Makefile.am with file on this link https://pastebin.com/WaJrKete

4.3

Edit tcl/target/nrf52.cfg as

#---------------------------------------------------------------------------------------------------------------------------------
#
# Nordic nRF52 series: ARM Cortex-M4 @ 64 MHz
#

source [find target/swj-dp.tcl]

if { [info exists CHIPNAME] } {
        set _CHIPNAME $CHIPNAME
} else {
        set _CHIPNAME nrf52
}

# Work-area is a space in RAM used for flash programming
# By default use 16kB
if { [info exists WORKAREASIZE] } {
   set _WORKAREASIZE $WORKAREASIZE
} else {
   set _WORKAREASIZE 0x4000
}

if { [info exists CPUTAPID] } {
        set _CPUTAPID $CPUTAPID
} else {
        set _CPUTAPID 0x2ba01477
}

# Work-area is a space in RAM used for flash programming
# By default use 16kB
if { [info exists WORKAREASIZE] } {
   set _WORKAREASIZE $WORKAREASIZE
} else {
   set _WORKAREASIZE 0x4000
}

swj_newdap $_CHIPNAME cpu -expected-id $_CPUTAPID

set _TARGETNAME $_CHIPNAME.cpu
target create $_TARGETNAME cortex_m -chain-position $_TARGETNAME


adapter_khz 1000

$_TARGETNAME configure -work-area-phys 0x20000000 -work-area-size $_WORKAREASIZE -work-area-backup 0

flash bank $_CHIPNAME.flash nrf52 0x00000000 0 1 1 $_TARGETNAME
flash bank $_CHIPNAME.uicr nrf52 0x10001000 0 1 1 $_TARGETNAME

if { ![using_hla] } {
        cortex_m reset_config sysresetreq
}

#---------------------------------------------------------------------------------------------------------------------------------

4.4 create empty file src/flash/nor/nrf51.c

step 5: Edit openocd-code/src/flash/nor/nrf52.c as per primalcortex.wordpress.com/.../

step 6:

./bootstrap
./configure
make 
make install

step 7: create nrf52832.cfg file & add following lines in it

#nRF52832 Target
source [find interface/stlink-v2.cfg]

transport select hla_swd

source [find target/nrf52.cfg]

step 8: execute

openocd -d2 -f nrf52832.cfg

step 9: Open another terminal & execute ->

telnet localhosta 4444

then

> reset
> reset halt
> nrf52 mass_erase
> program demo.hex verify
> reset

This will load the code into nRF52832 flash.

Hope this will help.

Hi,

nrfjprog won't work, as this is built on top of the J-Link driver and only support Segger J-Link debuggers. You can try this tutorial, which seems to describe what you are looking for.

Best regards,

Jørgen
