Hi @raffiniert
Can you tell me if you explicitly suspended the flash in your code like below?
// Put the peripheral into suspended state.
int err = pm_device_action_run(qspi_dev, PM_DEVICE_ACTION_SUSPEND);
In the older versions of nrf connect I had to suspend the flash with ported arduino code. In my last go the above code was used. Maybe a recent update removes the need for explicit suspend of the flash. If so, I’ll update my example code. I’ll also double check that it doesn’t brick the xiao.
