This is a different issue than the one asked about in the original post, so please open a new ticket for this.

Separating each distinct issue into their own tickets makes the forum much easier to read and search.

Hi,

Yes, I have seen that and corrected that, now this crash is resolved.

In addition to that, fort he below shared prj.conf file, can you explain to me the use of some config parameters, if they are not useful to my application I will remove them to reduce application size:

The failing assert seems to be this one in MessagePool::Free :

void MessagePool::Free(Message *aMessage)
{
    OT_ASSERT(aMessage->Next() == nullptr && aMessage->Prev() == nullptr);

    FreeBuffers(static_cast<Buffer *>(aMessage));
}

Do you make any calls to this function in your code? If so you should check those.

In your prj.conf you have: CONFIG_ASSERT_NO_COND_INFO=y and CONFIG_ASSERT_NO_MSG_INFO=y.

Set these to n and see if you get more info from the assert.

and when I run

arm-none-eabi-addr2line -e zephyr/zephyr.elf  0x0004feb6


I get following output:
/Users/bhumika/Project/Zipnet_Zephyr/zephyr/lib/os/assert.c:46


So basically I get a k_panic(); in my code, but what exactly causes this K_panic() I have no idea.

Also "ASSERTION FAIL @ WEST_TOPDIR/zephyr/subsys/net/lib/openthread/platform/misc.c:36", at this location I have following code:

void otPlatAssertFail(const char *aFilename, int aLineNumber)
{
	__ASSERT(false, "OpenThread ASSERT @ %s:%d", aFilename, aLineNumber);
}

Can you help me fix this assertion error?

RE: Error in west compilation in zephyr in shell_uart.c

Øivind — Thu, 17 Mar 2022 13:18:03 GMT

Try adding CONFIG_SHELL_BACKEND_RTT=y. You can also try CONFIG_LOG_PRINTK=y

If that doesn't work, it would be great if you could tell me where in your code that it fails.

RE: Error in west compilation in zephyr in shell_uart.c

Bhumika — Tue, 15 Mar 2022 04:31:32 GMT

I have in prj.conf file all CONFIG related to the following functionality:

1. ADC

2. Flash read and write

3. I2C sensor read

4. RTC

5. Openthread node in SED mode

6. Openthread joiner enabled and node not pre-commissioned

As far as logging is considered, I want my logs only on JLink RTT platform and no where else.

want to disable UART shell in the code.

Could you post your prj.conf file here?

RE: Error in west compilation in zephyr in shell_uart.c

Bhumika — Mon, 14 Mar 2022 06:26:32 GMT

hi,

I am not planning to make any printf() calls, if there are any, I want those to be printed on JLink RTT logs.

So yes, this is my question, how can I enable only RTT logs, with overflow enabled with a buffer of 512 only.

All other printf() calls can be replaced with RTT logs.

RE: Error in west compilation in zephyr in shell_uart.c

Øivind — Fri, 11 Mar 2022 12:59:04 GMT

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?

RE: Error in west compilation in zephyr in shell_uart.c

Bhumika — Fri, 11 Mar 2022 12:24:28 GMT

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

RE: Error in west compilation in zephyr in shell_uart.c

Øivind — Fri, 11 Mar 2022 12:01:36 GMT

You can try adding CONFIG_SHELL=n or CONFIG_SHELL_BACKEND_DUMMY=y

Only one of them at a time.
