Ssegfaultdev.elf my MCU has MPU so I am trying to use one with the mpu

Here's a similar question with the discussion which already answered question https://freertos.org/FreeRTOS_Support_Forum_Archive/August_2017/freertos_Setting_compiler_path_to_ARM_CM4_MPU_showing_error_300b24d2j.html Hope you find it useful.

also do you also avoid using MPU? I mean I can port without MPU easily. But porting MPU one giving me nightmare

So far I didn't need so haven't tried ARM_CM4_MPU since STM32F446RE uses Cortex-M4 core with Floating point (ARM_CM4F). I keep things simple & avoid exploring features that I don't need for immediate future projects

hey guys a newbie question - does esp32 c3 support wifi HALOW , if yes how can we access it . IF not what are other alternative development environment we can use to work with wifi halow .

I don't think esp32 modules support's wifi HaLow but you can check FGH100M module from Quectel https://www.mouser.in/new/quectel/quectel-fgh100m-modules

wifi
halow is very new and you need some special equipment

ZacckOsiemo•11/18/24, 10:35 AM

and even then you need a pair at least I got one thinking i could play with it but turns you need at least 2

Hello Everyone, I have tried and implemented CAN bus protocol. I have faced many issues, I went through them and fixed them at the end
I am very excited to share those experience with all of you. We are having a chit chat session on CAN Bus this Wednesday 9pm(GMT+6) all of you are Invited mybe It won't be very detailed but it CAN give you a good push to start your journey with CAN Bus. Let's share and grow together

@Event Pings, also check out the other events lined up this week in the server events tab. We've got (now) four cool events that consist of (now) everything from CAN to our Advent of Code plans to Gesture Recognition with TF Lite and FreeRTOS:

Wednesday: https://discord.gg/cHNGvqMJG9?event=1308368105608839191
Friday: https://discord.gg/cHNGvqMJG9?event=1308363954132877344
Saturday: https://discord.gg/cHNGvqMJG9?event=1308364313261510696
Sunday: https://discord.gg/cHNGvqMJG9?event=1305194526926966894
(And don't forget to mark your calendars to join our friends @JoeSchneider and @DJ Presto in the 12/12 webinar "Medical Development is Broken" by signing up for event reminders here: http://bit.ly/3YWTy1m)

Will you discuss hardware aspect also or only firmware?

once SPI controller/peripheral drivers get merged
will think of it

@ZacckOsiemo can you remind us of the sample code/project from your last AI with FreeRTOS Engineering Hour session? What's in it and how does it relate to the session this Sunday?

Bbruce_wayne Will you discuss hardware aspect also or only firmware?

Its going to be a few repos this week we are looking at training the Tensorflow model, this will be a couple of repos. I will share them ahead of time.

in I2C also
i have a lot of pending

Hardware design for CAN bus. Differential signal routing, bus protection, preferred architecture for robust development, etc

segfaultdev.elfOP•11/19/24, 10:06 AM

hardware design would be hard since I am mostly software guy but I can discuss about differential signal, can frame etc

it's a hacking session, we just wanna hang out and make you feel weird as you code, thats what we do to everyone there, we just question your identation and semicolons

ZacckOsiemo•11/19/24, 10:11 AM

@melta101 basically you don't have to wait until it is upstream

ZacckOsiemo•11/19/24, 10:12 AM

sharing where you are today will help

my MCU has MPU so I am trying to use one with the mpu
