the issue is the whole applicaion sometimes crashed, even i put a wdt in app_sched_execute().It confused me.. maybe it's about the softdevice.I've no idea. s110 7.0.0 and sdk 6.1 ? I'm not so sure,keil seems updated something...and i tried uninstall sdk6.1 it work all right ...

so,it means if i wanna to jump from applicaion to bootloader, because of no MBR support in S110 V6.2.1.I can only manually clear the register in 0x3FC00.Got it.

@Jasonbu: What kind of issue have you got with S110 v7.1.0 ? Which SDK did you use ? I would suggest you to try the bootloader comes with SDK v8.0 with S110 v8.0 (if you use chip v2, remember to disable CPU concurrency option). It fixed the issue with bonding and ATT table caching on the phones.

On softdevice v6.x and earlier, we don't have the MBR that support softdevice and bootloader update so the API is a little bit different.

To be able to forward the interrupts to bootloader, you may need to do it manually inthe application. We have sd_softdevice_forward_to_application() to forward to application, but not from application to bootloader. Usually on S110v6.x, if you want to jump to bootloader, you can simply set in retention register a flag then do a softreset to jump to bootloader. The vector table is forwarded to bootloader by default when softdevice booting.
