NRF_ERROR_SVC_HANDLER_MISSING when vector table base set

[Ben.Qin]

Hi there! Running a bootloder of sdk 9.0 on nrf51822, a problem occurred in a special way. In a normal way, program softdevice and bootloader with studio respectively, then transfer firmware with toolbox. Everything works well. In a special way, merge softdevice, application and bootloader, and then program them to nrf51822 with studio. It works now. Next an event triggers calls sd_power_gpregret_set(0xB1); and sd_nvic_SystemReset(); in order to enter the DFU mode. This call sd_softdevice_vector_table_base_set(BOOTLOADER_REGION_START); reutrns NRF_ERROR_SVC_HANDLER_MISSING in bootloader. Am I missing something? Thanks!

Got the reason in this zone. One more question, if I initialize the softdevice every time the system resets, would the bootlader work well? Although I'll follow the official way in the following products, I need to support the former products too.

Hi Ben,

It should works fine, the only draw back is that you won't be able to use RAM to store bonding information as we are doing now (we don't do reset, but jump directly.

Another option for you is to store the bond information on flash, then you can do a reset and read the bond information from flash out.

Thanks a lot. Hung!

@ben-qin Can you explain the reason you found for your first question?
