Re: [Zephyr-users] assertion fail in nordic nrf5 i2c driver
The I2C driver has since been completely rewritten to use nrfx, our common driver codebase.
Would it be possible for you to try with current master (or at least 1.13) to see if you still face the issues you mention?

Subject: [Zephyr-users] assertion fail in nordic nrf5 i2c driver
I am using a lis2dh12 with a nrf52840, and am on occasion seeing an assertion.
It happens in the i2c_nrf5_read
err=0 txd=0 rxd=0 stopped=0 errsrc=0x0
ASSERTION FAIL [data->stopped] @ <snip>/zephyr_new/drivers/i2c/i2c_nrf5.c:142:
We are based off of 5890004ea72066fb4b1e8100bb289fb5a00646a5 ( r 1.12)
Can someone shed light on whats happening? It looks like I am waiting for the EVENTS_STOPPED to hit in the isr, but seeing the data->stopped is not set, perhaps its not?
Are there any remedies? It looks like this condition should be benign, am I mistaken?
