Upload .hex on nrf52 in Makefile

[Nils Minor]

Hi,

for development i am using gcc and makefile on osx. I wanted to automate my makefile with the possibility to upload directly the hex file to my nrf52 devboard.

All Makefiles from Nordic using nrfjprog in this case, but i am running osx.

In the moment i use the following commands

nupload: upload.jlink 
$(JLINK) $(OUTPUT_BINARY_DIRECTORY)/upload.jlink

upload.jlink: echo "device $(DEVICE_NAME)\nspeed 1000\nloadbin $(PWD)/$(OUTPUT_BINARY_DIRECTORY)/nrf52832_xxaa.bin $(FLASH_START_ADDRESS)\nr\ng\nqc\n" > $(OUTPUT_BINARY_DIRECTORY)/upload.jlink

It works correctly but i am not shure if i had to enable something.

I also need a method for erasing. If i have a look on nrf51 i do not understand what

erase-all.jlink:
echo "device $(DEVICE_NAME)\nw4 4001e504 2\nw4 4001e50c 1\nw4 4001e514 1\nr\nexit\n" > $(OUTPUT_BINARY_DIRECTORY)/erase-all.jlink	

does this stand for ?

So maybe some can give me advice in correct using link to upload, recover, erase and upload soft device :)

Also if i want to use soft device how are the addresses for this in my makefile?

Bes regards, Nils

Not a complete answer for you, but a tip: The new development kits will show up as a block device/flash drive when connected. It is possible to copy a file to this folder, and it will automatically be flashed and the device reset. Is this something you could use? This would need you to merge the hex files in advance though.

To erase the chip you have to enable erase and erase using the NVMC. It is documented here: infocenter.nordicsemi.com/.../Chunk208541660.html

That would be:

w4 4001e504 2  #CONFIG register, enable erase
w4 4001e50c 1  #ERASEALL register

To flash the softdevice you can write:

loadbin $SOFTDEVICE 0x0  #flash in address location 0

To flash the application you can write:

loadbin $APPLICATION 0x1f000  #flash in address location 0x1f000  (s132_nrf52_1.0.0-2.alpha version)

A script to erase, flash SD, flash application and reset would look something like this:

device nrf52
speed 1000
w4 4001e504 2
w4 4001e50c 1
sleep 100
r
loadbin $SOFTDEVICE 0x0
loadbin $APPLICATION 0x1f000
sleep 100
r
g
exit

Thanks, this worked for me :)

Wow, I've been looking for exactly this for days! :) Thanks @stian!

While using DFU and with respect to this: infocenter.nordicsemi.com/index.jsp nRF51:

• the softdevice no longer starts at 0x0 right, but at 0x1000?
• Or it starts at 0x0 since the MBR is part of the Softdevice?
• And the application starts at 0x0001 B000?

Thanks!
