Hello everyoneI'll receive soon a custom board based on an STM32 microcontroller (still not sure about the specific part number) and I'll have to flash FW updates on it. A few questions about it:1) There's a 4 pin header connector on the board (VCC, ...

Hello everyone.I'm interfacing my STM32F745IET6 (master) with an SPI device.I'm using SPI1 interface running at 50 MHz, I was wondering if there's some "rule of thumb" to calculate time needed (in terms of clock cycles) to write n bits over the bus. ...

Hello everyoneIs it possible to program my STM32F745 via RS-485 using the integrated bootloader?My idea is using USART1 (as written in the AN2606) and a transceiver to do that. Has anyone done something similar? Thank you very much in advanced. Best ...

Hello everyone,I want to use the MT46V64M8P-5B:J 64Mx8 SDRAM by Micron with a STM32F745IET6 microcontroller.I'm configuring the peripheral on stm32IDE and it looks fine, the configurator automatically set PG8 as clock signal. Still, the SDRAM require...

Hello @VivekBorse I'm facing the same issue with my custom board based on the STM32F745IET6.Did you solve this? If yes, how?Thank you very much

Thank you very much. This confirms my initial concerns.

Whato do you mean by "Control the program"? Basically, I just want to provide a way to flash the IC with future software upgrades, that's why I was thinking about using the bootloader.

Thank you very much.So this is the pin configuration to boot the chip: I was checking the schematic of the STM32F76 Evaluation Board since it uses an RS-232 transceiver to boot and program the chip. I see it uses flow control to set both RESET and BO...

@TDK thank you very much.Adding external circuitry wasn't an option for me since delay is a major concern. I'll just choose a different memory IC. Any suggestions? Best regardsNick
