Hi kbb64 ,

The sdk_config.h that comes with the examples\ble_peripheral\ble_app_template example should have the defines you need. If you are not using the SoftDevice, take a look at the sdk_config.h for examples\peripheral\template_project instead.

Hi,

It’s probably caused by how Ozon is handling the “Download and Reset Program” in combination with the SoftDevice, i.e. it’s not starting the application in a stream-lined fashion.

Note that we have now released SDK 14.1, where we have added support for Segger Embedded Studio (SES) IDE. You can use Segger Embedded Studio for commercial and non-commercial purpose with Nordic Semiconductor devices free of charge without any code limit. This could be a better option for you than your current toolchain setup. See this article for more information.

You can download SDK 14.1 here.

You can download Segger Embedded Studio from here.

Ozone isn't behaving as if it's a typical hardfault, it normally will indicate that I'm in the hardfault handler but in this case it jumps to address 0x8CC which is a LDR (R3, [R3, #+0x0C]). And continuing execution in Ozone results in execution being immediately paused at the same address. It appears as if the CPU just stopped...

And you are correct, timer_list_handler_shed() is the function calling the NVIC_SetPendingIRQ. The full function call stack is:

power_management_init() -> nrf_pwr_mgmt_init() -> PWR_MGMT_TIMER_CREATE() -> app_timer_start(m_pwr_mgmt_timer, APP_TIMER_TICKS(1000), NULL) -> timer_start_op_schedule(p_node, timeout_ticks, timeout_periodic, p_context) -> timer_list_handler_sched() -> NVIC_SetPendingIRQ(SWI_IRQn)

Hi,

By crash you mean hardfault? Is it the function timer_list_handler_sched() that is calling the NVIC_SetPendingIRQ() that is causing this?
