Hi, I have bought STM32H743VGT6 and want to make bootloader and application. The issue is that its memory layout is confusing. In documentation and generated application I see/assume flash memory is:0x8000000 size 0x80000 (512kb bank1?) // bootloader...
Hello,I am designing a high-speed data logging architecture using STM32H743VIHx. I would like the community to validate my DMA architecture and answer specific questions about eMMC access. I did not find answers in the forum and I am also not an expe...
The STM32G0B1 has a very ugly bug in the bootloader.When I have a write protection on a flash memory area:WRP1A_STRT = 0x0 --> 0x08000000WRP1A_END = 0x1 --> 0x08000800 and then I upload a new firmware to this area the firmware will not be written, be...
I am using the NUCLEO-L433RC-P with the blue top switch (pin PC13) configured as a wake pin.When the switch is pressed, the MCU should wake, then turn the LED on, then shutdown.But for some reason the MCU wakes twice as observed by the following beha...
ST moderator: post split from this thread. @mƎALLEm , Thanks for this information. So, it appears, that - apart from the confusing footnote in Fig.118 - the probem was probably somewhere in @y_liosha 's code, correct? Can you also please have a look...
Hi All, In my application, I am using the STM32L451RCT6 and trying to configure COMP2 with the internal Vref as a reference (specifically 3/4 Vref). For some reason, it never worked. I was only able to get it working when using DAC_CH1 or an externa...
The AN3156 explains on page 18 the Read Unprotect Command:This command is selected when wValue = 0 and the first byte of the buffer sent by the host is 0x92. The buffer length is only one (the command) byte.The host sends a DFU_DNLOAD request with th...
C5 implements a way to de-activate selected boot devices. This will allow to use the system bootloader on custom board were some activity on pins used by the bootloader but not used for the bootloader would inhibit use of the bootloader. This featur...
Hi,I already tried to search for previous threads that could help me (like this one), sadly without success.I'm currently studying the ADC peripheral on STM32F3DISCOVERY from the reference manual. I started writing a simple program to measure a tensi...
We are using STM32H743 and STM32H745 in our product lines and embedded bootloader is used for boot loading. The PB14 pins is used as Debug Uart on USART1. The PA9 pin is left unconnected. Its Not Connected pin. Is there any impact on this upgrade. ...
