Hi there~
I'm working on nRF52840 DK board.
I want to change nrf_log max number of arguments.
After I finished the modification, and print log with more than 8 arguments(7 arguments is ok), a hardfault was occurred.
Here are the background infomations:
board: nRF52840 DK
SDK: 15.3.0
example code:
- CLI example(SDK/examples/peripheral/cli)
code change:
- add macro(LOG_INTERNAL_# in nrf_log_internal.h)
- changed NRF_LOG_MAX_NUM_OF_ARGS from 6 to 10
- add functions (nrf_log_frontend_std_# in nrf_log_frontend.c)
- modified nrf_log_std_entry_process function(add case code when the arguments number is from 7 to 10)
Here is the debugging capture with SES
This is the code for printing log.
NRF_LOG_INFO("%d %d %d %d %d %d %d %d %d %d", 1, 2, 3, 4, 5, 6, 7, 8, 9, 10);
With the debug capture I found that the hardfault caused by the bad address of argument that passed by nrf_cli_process function.
And the address value is the 8th parameter value that used by NRF_LOG_INFO.
I tried to change the value of 8th parameter of NRF_LOG_INFO to other values(ex: 9), and the address of argument that passed by nrf_cli_process also changed(0x00000009).
Any advice will be nice~
Thanks~~!!
