Using NUCLEO-F401RE with DWM3000 v1.4 api v6.00.7/14, hardfault when try readdevid

[legent]

Hello,

Im trying to run the library and test the examples, as i mencioned on the tittle im using stm32cubeide, i made a port based on the project EVK3000_F429_CubeMX.

I followed this guide to import correctly the library to the project, works fine i think: System Hardfault when calling dwt_probe() - #9 by bruno

I used this code to test the spi conections and work fine:

DWM3000 with STM32L433 undefined reference in library

It looks ok for me, what STM32 are you using? I am using M4 family and it worked, but I don’t know if it works with M0,M1, etc. I also used hfp, I don’t know what sfp is for, you may wanna try it. Anyway here is a piece of code I used for going directly to DWM3000 (just using some code borrow from the old DWM1000 api) so you can be sure that can establish communication with DWM3000; not using DWM3000 api just to make sure your hw setting and etc is ok. Try with SPI in low speed also (3Mbps, 4Mb…

when i test the ex_00a_reading_dev_id example, the dwt_probe() return -1(ERROR) and then dwt_readdevid() jumps directly to hardfault_handler. I can confirm that dwt_probe uses the readspi function implemented:

idk whats happening but what i understand is that when it enters hardfault, its because of memory access error, idk what am i missing.

Thanks in advance for response.

Hi,

Have you resolved this issue? I so, can you please help me? I am facing the same issue. It is going into Hard Fault. I am using Nucleo-F411RE in STM32CUBEIDE.

Thanks in advance

Hello,

my problem was a physical conection problem, i was conecting everything with a protoboard and wires, so we made a pcb and worked fine.

hope it helps and sorry for late response.
