gonna look into it

segfaultdev.elf•11/15/24, 11:27 AM

also I will program another stm on the other end so that I can verify everything better

Hello everyone,
I am trying to run Mongoose WS on my stm32h753zit6 board but every example they use NucleoH753ZI. They are using RMII mode but in my case I am using MII do I need to update something on library. I tested couple times with different implementations but still my ethernet does not assigning the IP. I am adding the serial log.

Can anybody did this before, can anyone help me about it?

segfaultdev.elf•11/15/24, 12:59 PM

that issue is fixed

segfaultdev.elf•11/15/24, 12:59 PM

Everything working fine

segfaultdev.elf•11/15/24, 1:00 PM

the issue was my breadboard XD

ZacckOsiemoOP•11/15/24, 1:00 PM

what was the issue

segfaultdev.elf•11/15/24, 1:00 PM

ZZacckOsiemo what was the issue

segfaultdev.elf•11/15/24, 1:00 PM

I was using an old breadboard of mine which was covered by dust

segfaultdev.elf•11/15/24, 1:00 PM

and the result you know already

segfaultdev.elf•11/15/24, 1:02 PM

Then I took my multimeter and checked the voltage of VCC and GND

this is the way.

ZZacckOsiemo everytime hey! I got stuck on a stream for 40 mins because of a breadboard

segfaultdev.elf•11/15/24, 2:48 PM

So many things happens
I was using a STM31F411 since the First day of learning STM32 but today after creating project I saw it doesn't have any CAN Peripheral
then I soldered another Dev Board known As BluePIll
Then my breadboard started playing with me after fixing it my receiver end weren't jumping into ISR
but now everything is working perfectly

segfaultdev.elf•11/15/24, 2:49 PM

It was a long day

segfaultdev.elf•11/15/24, 2:50 PM

finally I am ready to take a break

Good shout, CAN will show an error when messages are not acknowledged, in default configurations that will cause the message to be sent repeatedly forever

I was checking then but it was mainly breadboard issue

now everything is fixed

aymen ammari•11/15/24, 4:13 PM

Just like @melta101 said they all work with PLC except for the camera ones they are connected to an actual pc with their software to control it with from basic functions to more complicated ones

Mmelta101 Firmware extraction or shell access?

Marvin•11/15/24, 4:15 PM

can be both. shell access can lead to the other.

MMarvin can be both. shell access can lead to the other.

melta101•11/15/24, 4:29 PM

Yep
I have done this to an old router

Marvin•11/15/24, 4:46 PM

Bet that was fun.

same here

segfaultdev.elf•11/16/24, 2:57 AM

and Then Finally Peace

segfaultdev.elf•11/16/24, 2:57 AM

It took me almost a day

ke7c2mi•11/16/24, 12:37 PM

Yeah once it works it's very solid.

Twitches thinking of adjusting sample point

It seems like you used ARM_CM4_MPU architecture from GCC folder of FreeRTOS source files. To make it work with STM32F4 you must use ARM_CM4F folder and its associated port.cport.c and portmacro.hportmacro.h Once you fix this then just make sure FreeRTOSConfig.h configured properly and then project will compile fine. Let me know if issue persists even after making changes

Umesh Lokhande•11/17/24, 3:38 AM

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
