nrf52832 flash programming

[Sébastien Le Ray]

Hi,

Is there an extensive documentation about programming process of a nrf52832 using keil? I just spent hours figuring out that I had to use Softdevice erase flash algorithm to get rid of a laconic "programming failed" under keil. I cannot find any documentation on this, anywhere

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

Hi,

Thanks for your time.

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

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).

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.

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