Hi,

I see that you are trying to add some logging to z_impl_flash_erase() . This function will call this function flash_nrf_erase() -> https://github.com/nrfconnect/sdk-zephyr/blob/v3.2.99-ncs1/drivers/flash/soc_flash_nrf.c#L198 , so add your logging there instead.

Thanks for your reply! I have removed LOG_MODULE_REGISTER(flash) from D:\ncs\v2.3.0\zephyr\include\zephyr\drivers\flash.h. And I also addCONFIG_LOG_DEFAULT_LEVEL=4 to 6403.prj.conf. But west build still failed with error: '__log_level' undeclared. Please unzip log_level_undeclared.zip for detail information.

Hi,

There is already a log module registered for soc_flash_nrf.c

https://github.com/nrfconnect/sdk-zephyr/blob/v3.2.99-ncs1/drivers/flash/soc_flash_nrf.c#L24

I have removed including printk.h in flash.h. But west build still failed with redefinition of '__log_current_const_data' error message. Please refer to redefinition.txt for detail information.

Procedure to reproduce this issue.
1. Unzip minimal_log_flash.zip to D:\ncs\v2.3.0\nrf\samples folder.
2. Unzip custom_nrf52832.zip to D:\ncs\v2.3.0\nrf\boards\arm folder.
3. Copying flash.h to D:\ncs\v2.3.0\zephyr\include\zephyr\drivers
4. cd D:\ncs\v2.3.0\nrf\samples\minimal_log_flash
5. west build -b custom_nrf52832

Try CONFIG_LOG_DEFAULT_LEVEL=4

Main problems issue , I had replied for the other topic . You may check the root case with my experience.

Do you mean it should build okay if I remove including printk.h?

For Matter development project , we use the NRF connect SDK 2.4.0 toolchain with VS Code IDE.

The debug console message function is LOG_INF()

I know that the SES or Keil IDE. Project for BLE or thread within Software device in Zephyr OS , The debug message function is printfk() as before.

The redefinition means you can't include the log.h and printk.h at the same time.

Thanks for your reply! I added the following code to D:\ncs\v2.3.0\zephyr\include\zephyr\drivers\flash.h.

#include <zephyr/logging/log.h>
#include <zephyr/sys/printk.h>

LOG_MODULE_REGISTER(flash);

static inline int z_impl_flash_erase(const struct device *dev, off_t offset,
size_t size)
{
LOG_INF("z_impl_flash_erase() e");
const struct flash_driver_api *api =
(const struct flash_driver_api *)dev->api;
int rc;

rc = api->erase(dev, offset, size);

return rc;
}

Please refer to redefinition_of__log_level.txt for west build error messages.

Try LOG_INF() function.
