Error in west compilation in zephyr in shell_uart.c

[Bhumika]

Hi,

I have removed UART from my custom board dts file as in my current application, I am not using UART for any transfer.

But due to this, I am unable to compile code as some internal logging/Device_DT is using UART.

I am getting the following error:

/zephyr/include/net/net_l2.h:164:22: note: expected 'struct net_pkt *' but argument is of type 'struct net_pkt *'

Can you tell me which file by default uses shell_uart.c?

How can I remove this error?

[Øivind]

Hi,

Try adding CONFIG_SHELL_BACKEND_SERIAL=n to your prj.conf file.

Hi,

I have done this and added this config in prj.conf.

Now my application is getting built, but I am facing a runtime crash in the application.

Following is the crash message:

When I checked the error file using the following command:

➜ build git:(master) ✗ arm-none-eabi-addr2line -e zephyr/zephyr.elf 0x000091f0

zephyr/lib/os/cbprintf_complete.c:1339

So it is giving an error in this file, can you help me in resolving this crash?

[Øivind]

You can try adding CONFIG_SHELL=n or CONFIG_SHELL_BACKEND_DUMMY=y

Only one of them at a time.

[Bhumika]

can you also explain to me the role of these configs in prj.conf?

[Øivind]

Checking if the problem is due to having shell enabled with no backend enabled.

CONFIG_SHELL=n would try to disable shell.

CONFIG_SHELL_BACKEND_DUMMY=y would instead keep shell enabled, but give it a dummy backend, so it won't run into issues due to lacking a backend.

It would be useful to know if your code contains any printf() calls, and if so where would you like those to be printed?
