Hi everyone!I found the following diagramm in AN2606 and my understanding was, that the bootloader will be executed when there is no valid content in flash memory.I know that boot pins or a jump from user code can be used to enter the ST bootloader, ...
Hello,I am using an STM32F407G-DISC1 to run an open source program called Picovoice. More specifically their project at the following link (https://github.com/Picovoice/picovoice/tree/master/demo/mcu/stm32f407/stm32f407g-disc1). Unfortunately they do...
Edit: I found the problem, and it is of course my own fault. Careful reading of the transceiver chip datasheet reveals that the Rx pin follows the Tx pin by design on some models, including mine. Leaving this post up for posterity. I'm having an issu...
Hello,I'm a bit confused about stack management on Cortex M7.In my SW I only use the MSP.I understood that the MSP can only be modified with a MSR instruction. However the SP can be modified with a "simple" LDR instruction.Does that mean that when I ...
This is not a discussion on the 'U0 as such (that'd need some time to sink in); just comment on the 'L0->'U0 migration document, AN6091. It's a very detailed and extensive document, and following items are just relatively insignificant minor issues/t...
hi,how to clean SRAM before jumping to main application from bootloader .In the SD card boot loader code we use local , global & static variable and what will happen to these variables during the transition from boot loader to main application .how ...
As I mentioned earlier I am trying to show red color on display screen this time using HAL_drivers. I attached a video on my one drive of me configuring a .ioc file and I builded it with 0 errors but when I flashed it to hardware, display module does...
Hello,In the example projects for LPBAM from ST, it is necessary to switch the RAM address to the SRAM region. This is because LPDMA has in Stop2-Mode only access to SRAM4.If I also want to use the RAM, which part of LPBAM (or maybe other parts) must...
I'm in the process of generating the Rust PAC for the STM32H755 using the svd files. I've downloaded the latest svd file v1.9 from here stm32h7-svd.zip I noticed that the file is incomplete as the MPU and NVIC peripherals are missing for both the CM7...
Hi,i am using STM32G0B1KB and the UCPD peripherals to implement an USB-PD device with 2 ports:- Port 1 is DRP & DRD device, USB FS data via STM32 USB peripheral, using TCPP03-M20.- Port 2 is Source only, not USB data capable, using TCPP02-M18.For por...
