No, nRFGo Studio can only use Jlink. But afaik you can use Keil to program using ULink

Can you use nRFgo Studio via ULINK ? How ?

It didn't connect for :/

@PW: I agree. It's better to start your development with an up-to-date platform.

Yes, I've updated IROM1 start address. I think, the best way will be do it with chip rev.3 :).

@PW: I assume that you have updated the IROM1 start address of the bootloader project to 0x3B800 as well. The reason you received NRF_ERROR_SVC_HANDLER_MISSING was because there was no MBR on the S210 v3.0.0. So there is no sd_mbr_command() in the Softdevice. It is implemented from S210 v4.0.0 (see the release note).

So you have 2 options:

Update API header to S210 v4.0.0
Use the bootloader from SDK v6.0 (application update only )

I changed in your example: #define BOOTLOADER_REGION_START 0x0003B800 and it "almost" works. When I call ble_stack_init(bool init_softdevice), it return: NRF_ERROR_SVC_HANDLER_MISSING after err_code = sd_mbr_command(&com); How does it work exactly? When button is high level hen chip is starting, shouldn't jump to my app?

@PW: Yes it should work. The register is just what we defined and used for the MBR and the bootloader. It's not really defined in the hardware itself.

What about UICR.BOOTLOADERADDR. According to nRF51_Series_RM_ver.2.1 there is no such of register. So I wonder, will examples I mentioned above work with chip rev.2?

Hi PW,

You have that issue because in DFU bootloader we don't use KEIL programmer to program, but we use nrfjprog.exe to program the chip. The default KEIL programmer doesn't program UICR.

You can have a look at the stock DFU bootloader example , Project Option -> Utilities -> Use External Tool for Flash Programming.

You can also have a look at this case.
