Hey I'm doing the same as you but I can't find "Softdevice algorithm". I only have "nrf52xxx Softdevice Erase" which I used for flashing the softdevice.

Hello ALL, I can confirm what written by Sébastien, with KEIL MDK5 and uLink2 ME it works. I am able to progra nRF52832 chip directly. Ican flash the SD separately from hex file and the full APP.

From my notes, in Target setup, For soft device target, debug tab, button settings, tab Flash download: Flash Algorithms: nrf5xxx Softdevice erase (this way it'll handle sd upgrade if needed). Check program & verify, RAM Algorithm: 0x20000000/size 0x2000. back in target setup, target tab, IROM1 Start 0, size given in SD release notes (0x1F000 for SD3), IRAM1 start 0x20000000, I guess size has no real effect (it's given by the start you'll set in app target). For app target, flash algo nrf52xxx, start 0x20000000, size 0x2000. Main params: IROM1 start 0x1F000 (see SDK release notes), size = chip flash size - start, IRAM1 start depends on which SD features you use, You'll have to set a random value (size is chip ram size - start) and debug the sd_enable call which will fail & return you the correct value. You'll need the last NordicSemiConductor::nRF_DeviceFamilyPack Keil pack

Try this one here. It can flash Softdevice and works with OpenOCD, Keil, CrossWorks and many others.

Which debugger do you use?

Any one found Solution ? i am facing the same issue?

The meaning of "flash algorithm" is the heart in my issue, it's a keil parameter when you use ST-Link debugger to flash stuff. Anyway I sorted it out, when upgrading SoftDevice with a ST-Link you'll have to use SoftDevice Erase algorithm (with a 0x2000 size), while app flashing needs SoftDevice (0x2000 size) as algorithm.

Hi Sebastien,

What do you mean by "flash algorithms"? Memory layout of the nRF5x chips is described in respective product specifications (you can see it on-line at infocenter as well). The rest is standard JTAG/SWD (which isn't invention of Nordic so you can find detailed documentation elsewhere) and SEGGER J-Link/J-FLash (if you really want to understand all background details then go to SEGGER web site).

Cheers Jan

Hi,

Thanks for your time.

I Already read (most) of them, but there's nothing about flash algorithms

Hi,

The Getting started with the nRF5 development kit-tutorial is a great starting point to get started with programming with Keil.

There is also a Getting started section in the official documentation at the Infocenter.

I would also recomment reading this blogpost describing how to add custom shortcuts for running nrfjprog commands like eraseall and programming SoftDevices from inside Keil.

Best regards,

Jørgen
