is there a limit to how many lines printk supports

[weightwatcherphil]

I am using nrfconnectsdk v2.4.0 with zephyr and I have a program with a large number of printk() statements.

is there anything in prj.conf that limits the amount of text I can print out to RTT

i use jlink to view the RTT output.

i have a custom board.using nrf5340.

i have a call   k_sleep(K_USEC(1000));

followed by

printk("power supplies are off\n");

and the print output never shows up on the RTT viewer.  i have many other lines on the RTT viewer.

so it looks like  I cannot print any more characters or somehow the k_sleep is not working.

thanks

RTT silently drops messages if the RTT buffers are full - especially on startup. One ms is not enough time to clear this buffer via USB.

what controls the size of the RTT buffers in prj.conf ?
