Dear Nordic Team,
I am working with the SDK 2.0.0 in Visual studio Code and with a custom board with a nrf9160. The board configuration is based on the nrf9160dk and has only minor changes.
At the moment I am trying to implement the nvs(none-volatile-storage) library into my project. I tested the sample on my custom board and this worked without any problems at the beginning.
After the successful test I incorporated the nvs library into my project and began to test it.
Unfortunately I encountered some problems with my implementation and also with the nvs sample. The initialization of the nvs stroage partition works fine and completes without any problems, but reading or writing always yield the same error namely the error -2 which is classified as ENOENT or " nor such file or directory". Also the sample always shows this error since the use of my own implementation. When debugging the functions it always fails at these lines:
zephyr\subsys\fs\nvs\nvs.c line 1166 to 1169:
if (((wlk_addr == fs->ate_wra) && (wlk_ate.id != id)) ||
(wlk_ate.len == 0U) || (cnt_his < cnt)) {
return -ENOENT;
}
The problem is that wlk_ate.id always shows the number 65535.
This is my proj.conf file:

The partitions.yml file also does not show any problems at least to my knowledge:

This is the logging I get for the nvs initialization:
