Hardfault on an sd_ble_gatts_hvx call in SDK12.3

[Dave_couling]

I've recently migrated from SDK11 to SDK12.3 using a FreeRTOS based applications. I seem to get a hardfault on a sd_ble_gatts_hvx call. There is no difference between my SDK11 and SDK12.3 application code. The function doesn't return an error code it simply freezes/gets lost.

My ble_thread is set to priority 2 as per the freertos Nordic example. A xTimer timeout triggers the sd_ble_gatts_hvx call to update a timestamp on the Central. This worked great on SDK11, but I needed the lower power SAADC module in SDK12.3. Hence the migration.

What could cause sd_ble_gatts_hvx to simple cause a full system hang up? Thread priority matches SVC calls, and the parameters are correct (haven't changed).

Please help anyone who seen something like this. Thanks.

Have you looked at this?

This applies to SDK 13, it produces compile errors on SDK12.3 which is what I'm suing.

[Susheel Nuguru]

what compile errors does it give?

[Dave_couling]

There were no compile errors in this case. I traced the issue down to a Thread priority which seemed to have changed priority setting from what I initialized it as. I re-install SDK 12.3.0 and re-built my code again on the freertos example. Seems to be working now, only saw this hardfault once today.

If the hardfault happened after the new file, then we cannot ignore it, even it happened only once. You must try to make it fall again. Try to run some tests that lasts for few hours, hopefully you hit the hardfault
