[SES] Where to get the right version of startup files?

[APU]

Hello everyone,

I try to import a project from Keil to SES,

I 'v read the instructions in this article.

Segger Embedded Studio - A Cross Platform IDE

Generally I have no question about those steps except one,

When mention "Adding nRF5 MDK Files", it offers two links to download the required files.

I noticed the files are entitle with "ses...", whereas in my original project it is "arm...".

As far as I know, "arm_startup_nrf52.s", "start_config.h" and "system_nrf52.c" revise as the version of "Device Family Pack" increases in Keil(Currently I'm using 8.24.1 in Keil),

I suppose the startup file to be used in SES should follow the same pattern which I expect there will be a website where I can browse every revision and chose the one I need. 

However there isn't(not sure if I use the right key words on Google), so I start to think if I can just take the files from Keil and import it to SES?

Then I compared the content of "startup_nrf52.s" between SES's and Keil's, discovered there are many differences which makes me wonder if can do so?

Any help will be appreciated.

I didn't find the import feature to be useful.

I found it simpler to just create a new project - from scratch - in SES, and then merge my application code into that.

I checked the content of "arm_startup_nrf52.s" resides in SDK 15.3.0, discovered it hasn't changed a lot compare to my project's.

In addition, I plan on using the GCC compiler in SES, which I then found a "gcc_startup_nrf52.s" in SDK 15.3.0.

I presume "arm_startup_nrf52.s" and "gcc_startup_nrf52.s" are semantically equal, so I chose it.

I would recommend you to use the SES startup files, choose one of the SES projects from SDK 15.3.0 to see which. The GCC variant is not compatible with thumb_crt0.s. 

Startup files:

/modules/nrfx/mdk/ses_startup_nrf52.s" />
/modules/nrfx/mdk/ses_startup_nrf_common.s" />
/modules/nrfx/mdk/system_nrf52.c" />

$(StudioDir)/source/thumb_crt0.s" />
