won't reset chip after dfu

[FormerMember]

Hi,

I am using keil uvision 5.17, SD 130, nRF 51822, dualbank bootloader.

---

I have programmed own application and merged bootloader, application, soft device.

I can do dfu as many as I want,

but the problem is I should push reset button whenever I finish dfu.

If I don't push reset button, I can't connect with smartphone.

---

My application have programmed from s130_hrs_with_dfu example,

I removed all of code exept dfu and device manage service.

Which part should I check to fix manual reset problem?

SDK10 bug

Solution : ..\dfu\bootloader\main.c

set(if you are using timer1, timer2)

if (bootloader_app_is_valid(DFU_BANK_0_REGION_START) && !bootloader_dfu_sd_in_progress())
{
    // Select a bank region to use as application region.
    // @note: Only applications running from DFU_BANK_0_REGION_START is supported.
    bootloader_app_start(DFU_BANK_0_REGION_START);
}

to

if (bootloader_app_is_valid(DFU_BANK_0_REGION_START) && !bootloader_dfu_sd_in_progress())
{

    NRF_TIMER1->TASKS_STOP = 1;
    NRF_TIMER1->TASKS_SHUTDOWN=1;
    NRF_TIMER1->EVENTS_COMPARE[0]=0;
    NRF_TIMER1->EVENTS_COMPARE[1]=0;
    NRF_TIMER1->EVENTS_COMPARE[2]=0;
    NRF_TIMER1->EVENTS_COMPARE[3]=0;
    NVIC_DisableIRQ(TIMER1_IRQn);

    NRF_TIMER2->TASKS_STOP = 1;
    NRF_TIMER2->TASKS_SHUTDOWN=1;
    NRF_TIMER2->EVENTS_COMPARE[0]=0;

    NVIC_DisableIRQ(TIMER2_IRQn);		

    // Select a bank region to use as application region.
    // @note: Only applications running from DFU_BANK_0_REGION_START is supported.
    bootloader_app_start(DFU_BANK_0_REGION_START);
