#16 RKNRFGO & nrfjprog crash when parsing softdevice info XML file

[_follower_]

Hi,

On OS X 10.8.5 with the tools installed from the RKNFRGO_V1.0.10.pkg download I get a crash on program startup when running RKNRFGO; and, nrfjprog crashes when doing anything related to softdevices e.g. nrfjprog -V, nrfjprog program --code _build/nrf51422_xxac_s310.hex --softdevice s310_nrf51422_2.0.0_softdevice.hex or nrfjprog update.

All the error logs are similar but the simplest one seems to be from nrfjprog -V:

Manually downloading the XML file from http://tcpdiag.dl.sourceforge.net/project/rknrfgo/SOFTDEVICEINFO/Softdevices.data I see it has version indicator <softdevices version="455583815">.

Wondering if this is related to the XML file content or the version of the XML parsing library or OS?

Thanks.

Ugh

scanUnsignedLongLong - Available in OS X v10.9 and later.

I didn't know that, will fix.

Thanks for the quick response!

Try 1.0.11 which I just put up. Uses the old method available on all OS.

There will come a time I'll have to give up support for older OSX because it doesn't get tested (I don't have anything that old) and we're coming close on 3 years of new functions.

Thanks so much for your quick action on this.

I noticed the new version before I got the ticket update ;) and tried it out.

It worked happily for me on OS X 10.8.5 programming the ble_app_rscs example on a pca10028 board with an s310 softdevice from both the GUI and CLI.

(I'd tried the older 1.0.7 release which would launch the GUI but didn't support the s310.)

I realise supporting older OS versions isn't fun so I appreciate you fixing this for me and doing it so quickly.

Thanks!

Thanks for the bug report - I rely on other people to test compatibility and as soon as you posted the stack trace it was a pretty easy fix.

I've been working on V2 on and off, it's a pretty different beast, it's what RKNRFGO would have been if I knew what I was writing when I wrote it originally. It's going to be Swift which will help with compatibility as that really flags up inconsistencies. I also now have a proper license for JLink so it should be a much better product. Swift probably means 10.9 is the minimum.

But it's a way away yet ..
