Change DFU start address and application start address

[Kadi Chang]

I changed the dfu start address to 0x00 and application start address to 0x8000. The application use the RTC0 IRQ to count the timer, but the RTC0 IRQ did not work correct(if the start application address is 0x00,the IRQ is work). Are there other config file should be modify for shift the start address?

Hi

I am not exactly sure what you are trying to do but you can change the start address for the bootloader by modifying the BOOTLOADER_REGION_START constant in dfu_types.h file in the bootloader project in the nRF51 SDK. You should also modify the IROM Start and Size addresses accordingly in KEIL ->Options for Target -> Target

The cortex_m0's Interrupt Vector Table is always fix in the 0x0000,cortex_m3 can change the vector table offset. I will try to modify the boot interrupt function to handle the app interrupt function call.
