For how much time system bootloader remain in bootloader mode
Hi In my hardware BOOT0 pin high after 12ms(Due to some hardware dependency) of power up, In this scenario MCU isn't going to bootloader mode, So I want to know For How much time mcu remain in bootloader mode at power up.
STM32F765 and LAN8720A
Hi, the LAN8720A has not the Tx_clk and Rx_Clk signals. Does the STM32F765 supports this configuration supposed I use the LAN8720A in slave mode routing to it the 25MHZ clock generated from the MCU from a ClockOut pin?Thank you.
DMAMR->SWR bit problem during using DP83822 instead of LAN8742
Hello,I used DP83822 instead of LAN8742 as ethernet phy in our custom pcb. I saw some comments that people can use DP83822 with small change on LAN8742 driver which belog to STM HAL Library. But i am not sure if it is possible.All the settings are tr...
Resolved! Can the STM32U5 integrated SMPS be used to power external components?
We're planning a design that uses the STM32U5 with built-in SMPS. Our device also uses USB, and the U5 packages we have are ones where VDDUSB is bonded to VDD so we must set VDD = 3.0-3.3V for the USB transceivers to work.We have other devices on ou...
In CubeMx perspective of IDE after choosing FileX SD interface there is a warning indicating a requirement that a device component class Device, group SDIO, sub HAL needs to be selected in the pinout tab. It is! So why I am I seeing this warning?
What am I missing?Also I am not thrilled that in the Packs window at the bottom right corner the "Sh..." and "Re..." columns cannot be expanded to see all of what is in those columns, and in the Component Dependencies windows indicates that all cond...
