using the nvs sample from here: https://github.com/nrfconnect/sdk-zephyr/tree/v3.4.99-ncs1-1/samples/subsys/nvs and configured for my board, the program crashes on the 323rd reboot (see terminal output below).
When I try to reflash at the point, the same thing happens. I can recover by configuring the app for a different board, like the 96b_notrogen/nrf52832, and flashing that. Then reconfigure for my board and flash, and it's good for another 522 reboots.
