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...
Hi,i am using STM32G0B1KB and the UCPD peripherals to implement an USB-PD device with 2 ports:- Port 1 is DRP- Port 2 is Source onlyI need the dead battery pulldowns for port 1, so I will connect the UCPD1_DBCCx pins with the UCPD1_CCx pins as descri...
hello,STM32F103C8T6 enables SPI1, but does not use MISO pin (PA6), can this pin reuse other functions? For example, timer function.Also, the PWM output can be observed in the software simulation, but there is no PWM output in the actual test. Is ther...
Using a Nucleo-F072RB. I am trying to get the output of CC1 to go low after the CPU does something. Everything is working as expected except I cannot get the line to go low. I have tried both variants of the CC1P bit and neither seems to work. I ...
