Nucleo 144 (STM32F767ZI) - Hard fault error, if the USB cable is disconnected from the USB_CDC port
Hi,I started working with a Nucleo 144 board (STM32F767ZI) and have implemented an USB-CDC according an example of ST (see: https://www.youtube.com/watch?v=h9T0RTu9Muc).Everything works well, but if I disconnect the USB line before startup the system...
How can i program Nucleol073RZ to program on the the fly from application without using boot pins , only from software application?
Is their any limitation to do this , is it possible with dual bank .kindly let me know if any code is available Thanks in advance.

Null pointer check needed in HAL_I2C_Mem_Write_DMA
(STM32Cube_FW_F1_V1.8.2/Drivers/STM32F1xx_HAL_Driver/Src/stm32f1xx_hal_i2c.c)In HAL_I2C_Mem_Write_DMA, hi2c->hdmarx may be null but this is not being checked. This causes a crash when invoking HAL_DMA_Abort_IT if there is no DMA used for receiving.bt...
Resolved! Is it possible to implement a dual CDC usb composite device on STM32F411?
I am selecting the microcontroller for an application that needs to implement an USB dual virtual com port (composite device with two vcom port). I would like to use the STM32F411 but i see that other people got problems trying to do it, maybe becaus...
Can't send one kind of IGMP msg on an STM32F746G Disco, but other kinds go out, and other protocols' msgs as well. A low-level hardware configuration issue? Not using STM driver.
I can send ARP, UDP, ICMP, and so on, and all the other IGMP messages, but not the IGMP V2 Membership Report messages. Wireshark doesn't show those at all, but does show the others going out. So I've written a low-level driver test that composes the ...
