TS06 – Day #18 – Downloading above an s130 softmachine

Posted on by crackingcontraptions_3voi0v

My experience below typifies the issues I am having with the Nordic stuff.  It reminds me of that famous bit from Hitchhikers Guide to the Galaxy:

“BEWARE THE LEOPARD”“But Mr Dent, the plans have been available in the local planning office for the last nine months.”
“Oh yes, well as soon as I heard I went straight round to see them, yesterday afternoon. You hadn’t exactly gone out of your way to call attention to them, had you? I mean, like actually telling anybody or anything.”
“But the plans were on display …”
“On display? I eventually had to go down to the cellar to find them.”
“That’s the display department.”
“With a flashlight.”
“Ah, well the lights had probably gone.”
“So had the stairs.”
“But look, you found the notice didn’t you?”
“Yes,” said Arthur, “yes I did. It was on display in the bottom of a locked filing cabinet stuck in a disused lavatory with a sign on the door saying ‘Beware of the Leopard’.”

I sent a query about flashing applications above the s130 softmachine to Nordic, having finally discovered a “beware of the Leopard” notice in the basement.

In the README file packed with s130 demo example your say:
“This SoftDevice release has internal changes that requires that the SoftDeviceis programmed onto the chip in a specific way. The following Nordic tools handle this:
– nrfjprog version 5.0.1 or higher- nRFgo Studio version 1.17.0 or higher.
If you have these updated tools, programming can be done as usual. If these tools are not available, a separate programming tool will be distributed with the release.”
Is this still the case or are there some magic parameters that I can set in uVision-4 that make it possible to flash directly out of the IDE?
Currently I’m getting the garbage in attached file.

Hi Michael, 
The newer J-link drivers requires more ram for the flash algorithm which is unfortunately not increased automatically, hence the error in your log file.  Please see attached screen shot of the correct flash configuration. This should let you flash directly from the IDE.
