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.elfOP•11/8/24, 7:30 PM

for that I added FreeRTOS as a source to my code

Techist•11/8/24, 7:30 PM

Ohhhhh, that makes much sense.

segfaultdev.elfOP•11/8/24, 7:30 PM

and everything working just fine

Techist•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.elfOP•11/8/24, 7:31 PM

To be honest I am more comfortable in this way

segfaultdev.elfOP•11/8/24, 7:31 PM

Every time I face some issues like this

segfaultdev.elfOP•11/8/24, 7:31 PM

it teaches me a lot

Techist•11/8/24, 7:32 PM

It's fine, then.

That's how I learnt FreeRTOS my self.

segfaultdev.elfOP•11/8/24, 7:32 PM

For example I learned this because of the issue

Techist•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.elfOP•11/8/24, 7:33 PM

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

segfaultdev.elfOP•11/8/24, 7:33 PM

so for now I will give it a try

segfaultdev.elfOP•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

Techist•11/8/24, 7:34 PM

Perfect.

Been awhile I worked on freeRTOS though.

TTechist Perfect. Been awhile I worked on freeRTOS though.

segfaultdev.elfOP•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

Techist•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.elfOP•11/8/24, 7:39 PM

you can check debug.c

segfaultdev.elfOP•11/8/24, 7:39 PM

for better information

segfaultdev.elfOP•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.elfOP•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

Techist•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.elfOP•11/8/24, 7:41 PM

in which file?

segfaultdev.elfOP•11/8/24, 7:42 PM

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

segfaultdev.elfOP•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...

Techist•11/8/24, 7:43 PM

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

I think so.

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

segfaultdev.elfOP•11/8/24, 7:43 PM

yeah no doubt about it

Ssegfaultdev.elf I usually use CMSIS so those are already defined

Techist•11/8/24, 7:43 PM

Ooh, makes much sense.

Yeah, I saw you your cmsis lib.

Techist•11/8/24, 7:43 PM

Kudos

segfaultdev.elfOP•11/8/24, 7:44 PM

but printf is invoking some system call which is more resource hungry so I get the functionality I need but a bit less cost

segfaultdev.elfOP•11/8/24, 7:45 PM

in the past I used to call my uart_send_char inside _io_putchar

segfaultdev.elfOP•11/8/24, 7:46 PM

also printf might use a larger buffer to store data i only made my buffer for 100 characters

segfaultdev.elfOP•11/8/24, 7:46 PM

which is more than enough to logging data

Techist•11/8/24, 7:48 PM

Well, the printk implementation is fine anyways.

It's justiable if you are using it for learning purpose.

segfaultdev.elfOP•11/8/24, 7:48 PM

also i thought it would better rather than sending character by character in each _io_putchar call

segfaultdev.elfOP•11/8/24, 7:49 PM

I am sending it as a buffer

segfaultdev.elfOP•11/8/24, 7:49 PM

:excusemewhat:

Ssegfaultdev.elf I am sending it as a buffer

Techist•11/8/24, 7:50 PM

Your uart driver still sends it per character, lol.

TTechist Your uart driver still sends it per character, lol.

segfaultdev.elfOP•11/8/24, 7:50 PM

yeah but in a single function call

Techist•11/8/24, 7:50 PM

So it doesn't make much difference, lol

TTechist So it doesn't make much difference, lol

segfaultdev.elfOP•11/8/24, 7:50 PM

maybe but it was one of my initial thoughts

Ssegfaultdev.elf maybe but it was one of my initial thoughts

Techist•11/8/24, 7:51 PM

It's entirely fine.

I need to join a meeting now.
I'm glad to know that you fixed your bugs.

Happy building.

it feels really good to share the process with someone
