Are you using any interrupt service routine for any other peripheral in your project? Say UART?

Now it is working fine and I am using uart for debugging

Ssegfaultdev.elf Now it is working fine and I am using uart for debugging

Ok, mind to share how you fixed it?

TTechist Ok, mind to share how you fixed it?

segfaultdev.elf•11/8/24, 7:27 PM

the issue was how I treated FreeRTOS

segfaultdev.elf•11/8/24, 7:27 PM

i added rtos as a library to my project

segfaultdev.elf•11/8/24, 7:28 PM

for that reason when compiling ISRs weren’t linked perfectly

segfaultdev.elf•11/8/24, 7:29 PM

since ISR’s are weekly declared so if my linker found them first their symbols are resolved and it won’t look for strongly implemented ISR’s which were implemented by FreeRTOS

segfaultdev.elf•11/8/24, 7:30 PM

for that I added FreeRTOS as a source to my code

TechistOP•11/8/24, 7:30 PM

Ohhhhh, that makes much sense.

segfaultdev.elf•11/8/24, 7:30 PM

and everything working just fine

TechistOP•11/8/24, 7:31 PM

You could use Cubemx next time to avoid such problem.

TTechist You could use Cubemx next time to avoid such problem.

segfaultdev.elf•11/8/24, 7:31 PM

To be honest I am more comfortable in this way

segfaultdev.elf•11/8/24, 7:31 PM

Every time I face some issues like this

segfaultdev.elf•11/8/24, 7:31 PM

it teaches me a lot

TechistOP•11/8/24, 7:32 PM

It's fine, then.

That's how I learnt FreeRTOS my self.

segfaultdev.elf•11/8/24, 7:32 PM

For example I learned this because of the issue

TechistOP•11/8/24, 7:32 PM

I only suggested using cubemx because it's more easier to use.

And it does all configurations underhood for you.

segfaultdev.elf•11/8/24, 7:33 PM

I know that maybe for rapid development I will use it but i am still learning

segfaultdev.elf•11/8/24, 7:33 PM

so for now I will give it a try

segfaultdev.elf•11/8/24, 7:34 PM

in case if you want to share some of your words in this

Ssegfaultdev.elf I know that maybe for rapid development I will use it but i am still learning

TechistOP•11/8/24, 7:34 PM

Perfect.

Been awhile I worked on freeRTOS though.

TTechist Perfect. Been awhile I worked on freeRTOS though.

segfaultdev.elf•11/8/24, 7:38 PM

even though it doesn’t make much sense but I love to write my own driver

Ssegfaultdev.elf https://github.com/undefined2001/FreeRTOS-BlackPill.git

TechistOP•11/8/24, 7:38 PM

I see you are using uart for logging purpose right?

Where are you calling the uart write function?

_io_puts private function?

segfaultdev.elf•11/8/24, 7:39 PM

you can check debug.c

segfaultdev.elf•11/8/24, 7:39 PM

for better information

segfaultdev.elf•11/8/24, 7:40 PM

_io_puts is called by a system call which is _write that is kinda overhead to what i exactly need

segfaultdev.elf•11/8/24, 7:40 PM

so I just wrote my printk to do the job

Ssegfaultdev.elf even though it doesn’t make much sense but I love to write my own driver

TechistOP•11/8/24, 7:41 PM

Yeah, I get you.

That's fine.

You should define your mask values and bit positions as macros too.

You'd have a hard time understanding that code in months to come.

TTechist Yeah, I get you. That's fine. You should define your mask values and bit posit...

segfaultdev.elf•11/8/24, 7:41 PM

in which file?

segfaultdev.elf•11/8/24, 7:42 PM

in main.c those configurations I did it was for rapid testing

segfaultdev.elf•11/8/24, 7:42 PM

I usually use CMSIS so those are already defined

Ssegfaultdev.elf _io_puts is called by a system call which is _write that is kinda overhead to wh...

TechistOP•11/8/24, 7:43 PM

Placing your uart write in io_puts should be able to achieve the same result.

I think so.
