I purchased a NUCLEO-G071RB and X-NUCLEO-USBPDM1 to development of my project.Then I wrote a sample program according to application note AN5418, but it doesn't recognize it as a connectable port to the UCPD monitor.Is it related to HWBoardVersionN...
Location of MAC address storage in stm32h7 memory
When configuring a network interface, there is usually a hard coded MAC address somewhere in a config file, which is used to setup the interface.In production this address needs to be unique (purchased). For example in some stm32f4 mcus, there is a s...
LwIP IPV6 DNS query failed
I have LwIP running on STM32+Cellular modem. The network is fine for IPV4. Now I am enabling IPV6.I can see my IPV6 address assigned with my IPV4.However, when I use lwip_getaddrinfo to have DNS query, but lwip_getaddrinfo return failed.Any hints are...

Resolved! How to use CMSIS 5.8.0 in the cubeIDE
Hi,I use the stm32f446re with the cubeIDE and would like to use FFT's with 16 bit float (arm_rfft_fast_f16) like in the CMSIS DSP 5.8.0.The older CMSIS library works fine with the other data types but i cant get the new (DSP 1.9.0) to work. I tried d...
USB on F103: ISRs, Disabling Interrupts and callbacks
Probably elementary stuff, but am brand new to ARM and STM32. I'm using a USB stack libusb_stm32 for learning. In this stack, when data arrives from the host PC, a callback in the USB ISR runs a function of mine to put the data into my queue. In this...
HAL_I2C_mem_read_dma return error
I'm connecting to a nucleo144 through configured pins and i2c connection a melexis 90640 (thermal scanner) I initially tried through Hal functions to call the device on the default address I had from the datasheet (0x33) but did not find it so I solv...
Resolved! Jump issue with custom bootloader (STM32H7)
Hello,I've made several bootloader in the past without so much problem in the past with F2, F4, F7, but this time, I have some serious troubles with a STM32H743BI :)The bootloader (using the first sector, 128kb) reads a bin file from the SD card and ...
