pynrfjprog verify

[J. Pritchard]

Greetings,

I am using pynrfjprog (9.0.0) to write a HEX file to an nRF52 device on the nRF52 DK. I am wondering if there is an easy way to verify the write using API.py, similar to how the in-line command "nrfjprog ... --verify" does so.

Some details about my setup:

• Windows 10
• nRF52 DK PC10040
• Python 2.7 Win32
• nrfjprog 9.0.0
• JLinkARM.dll 5.12g

Many thanks.

Hi,

There is no "nrfjprog.exe" functionality directly implemented in pynrfjprog, such as --program or --verify.

To do this, the following should work for the nRF52-DK:

from pynrfjprog import API, Hex

api = API.API('NRF52')
api.open()
api.connect_to_emu_without_snr()

test_program = Hex.Hex('blinky.hex')

for segment in test_program:
    content = api.read(segment.address, len(segment.data))
    if not segment.data == content:
        print "Segment data mismatch starting at address: {}, segment length: {}".format(hex(segment.address), hex(len(segment.data)))

api.close()
