HardFault debug

[Hansome]

During the firmware running, there will be a HardFault_Handler error occasionally.

Is there any way to locate the error source?

Is there any good way to catch the hardware exception? Thanks!

Hi.

Can you take a look at this page on StackOverflow?

Best regards,

Andreas

While setting APP_TIMER_CONFIG_IRQ_PRIORITY = 2, execute sd_ble_gap_conn_param_update will cause HardFault.
While setting APP_TIMER_CONFIG_IRQ_PRIORITY = 2, it is normal.
Why?

[Hansome]

APP_TIMER_CONFIG_IRQ_PRIORITY = 6 is normal

Hi.

You are running the APP timer with a higher IRQ priority than the SoftDevice, which is not allowed.

Best regards,

Andreas
