S120 Bootloader target options

Alev

Here Hung Bui (@hungbui) gave the good answer how to use bootloader with new S120 v.2.0.

I'm sorry, but can anybody check is I have a right settings on the Keil uVision options->target? Please note that I use a nRF51822__aa version and PCA10001 board (don't know if this matter or not).

Thanks.

    @Alev: Since you are using nRF51822 QFAA version, the main difference is that you have 16kB RAM instead of 32 kB as on QFAC variant. What you need to modify is the RAM setting:

    IRAM1 0x20002C00 0x1380

    IRAM2 0x20003F80 0x80

    Also because you are using PCA10001 you may need to mount the GPIO pin for button and LEDs to match with your board.

    Tool to generate .zip file from .bin or .axf (only for application, not for bootloader or softdevice)

    @hungbui Thank you a lot! Bootloader works!

    You point me to the documentation, but I'd read it earlier - the misunderstanding is in the next sentence from the SDK doc: In most cases, you can use the image in HEX format to perform the DFU. So, maybe, change/remove this sentence from the next SDK releases.
