Hello,After loosing days trying to implement paho mqtt with lwip and freeRTOS on a nucleo-F207ZG, I restarted from scratch and try do implement it in bare-metal mode.After a few hour of debug, using wireshark and mosquitto on a PC :- Connecting to th...
When I call the tx_event_flags_create() function, the code returns an error at the following line: else if (event_control_block_size != (sizeof(TX_EVENT_FLAGS_GROUP))) { /* Event flags group pointer is invalid, return appropriate error c...
I am trying to setup a local MQTT over a local network with port 1883 and B-U585I-IOT02A using the Nx_MQTT_Client example project. I have followed the steps in :https://community.st.com/t5/stm32-mcus-embedded-software/how-to-connect-stm32u5-b-u585iot...
In continuation of debugging the Ethernet ping test (from this thread) @Andrew Neil @bouazizm Main issue:When debugging the project, everything works well and i am able to ping the MCUWhen flashing the project, the ping test failsHere are the detail...
HiI am in the need to have USB working on the STM32U5G9DK2 board, however I specially do not need ThreadX, so I will configuring USBX in standalone mode. And I do not need to be using UART to complement my sample code as a lot of the sample codes fou...
Hi everyone,I’m trying to chain two timers on an STM32U585 so that:TIM1 generates a PWM on PA8 at 125 Hz (2 ms high / 6 ms low).TIM8 acts as a 20 µs sampler: it should reset and start counting at the falling edge of the TIM1 PWM, then fire its Update...
Hello,I have got STM32U5G-DK2 and i downloaded the example repository for the same. I build the example (Ux_Device_CDC_ACM) at the original location in Repository folder by opening it in STM32CubeIDE. It builds successfully but when I copy the same e...
Hello,I am working on the STM32H743BIT6 ethernet communication. I am using the external PHY DP83TC814RRHARQ1 for my requirement. I am configuring in CubeMX as USER_PHY under platform settings of LwIP. How can i communicate via external PHY.? Does con...
Hello,in all examples for the STM32H7S78-DK - including the TouchGFX applications - the frequency for the external APS256XXN-OBR-BG PSRAM is set to 200 MHz:extmem_list_config[1].PsramObject.psram_public.FreqMax = 200 * 1000000u; But in the datasheet ...
Hi, I tried adding APPKEY on the flash to read from bootloader to find if valid application there or not. I added as below in scatter file :EXCLUDE app_key.oAPPKEY 0x08043FF8 FIXED { ; 0x08013FF0 = last 16 bytes of 64KB appapp_key.o (.app_key)} and i...
