Can't program softdevice 5.2.1 into nrf51822 using Keil

[mac]

I have a custom board with an nrf51822 device. I also have Keil 5.12 and a ULINK2 and would like to program softdevice hex file into the nrf device. I have followed all of the documentation on the subject and yet I get the following:

Load "D:\Projects\SpecifiKali\SoftDeviceDownload\Objects\s110_nrf51822_5.2.1_softdevice.hex"

Full Chip Erase Done.

No Algorithm found for: 10001000H - 10001013H

Partial Programming Done (areas with no algorithms skipped!)

Partial Verify OK (areas with no algorithms skipped!)

If I use the same Keil settings and download softdevice 7.0.0 all is good. I have included some screen shots of my Keil configuration.

What is happening here?

Hi,

This procedure is not possible with SoftDevice versions that rely on settings in register UICR. It will only work with S110 v6 or newer.

edit This is because the flashing algorithm in Keil does not have access to the UICR area. You'll have to use nrfjprog to program this area, which only works on Segger based debuggers.

Best regards, Håkon

Thanks, I have switched from a ULINK to another J-Link device and I am now able to program the device using nRFgoStudio
