Hi,We have a design that at normal temperatures runs fine (21C). If it goes below 0C it starts failing to boot.The system has the Secure Boot Secure Firmware Update (SBSFU) system on it. We found that putting a delay at the start of the main() functi...
Hi,STM32H533 datasheet (DS14539 Rev 2) in table 88 says that RDY input setup and hold time are both 0.5ns. From my naive point of view it looks like superb value (RDY have to be stable only +-0.5ns around CLK edge). Isn't that a typo ? (STM32H7 PSSIs...
Hi,Ref.manual (RM0477 Rev 8) in chapter 32.3.3 PSSI clock saysIn case when PSSI transmitting data, then RDY pin is input.Datasheet (DS14360 Rev 2) shows setup and hold time of RDY pin (input) referenced to rising edge as well as data pins (outputs).I...
I am currently choosing an LSE and HSE crystal for an STM32H743 project. AN2867 includes tables of compatible STM32 crystals. There is also a crystal selection tool from ECS which i've used. My question is, after selecting a crystal from the tables, ...
Hello, this is DK.I am working on a project using stm32f429IIt6.I'm currently having an I2C problem at the end of my project.I2C1 uses PF 0, 1 / I2C2 uses PB 6, 7. The HW PCB completed, and the HW I2C pull up is the same.In I2C1 HAL code, the entire ...
The USB Host seems to not work if WFI is executed in the FreeRTOS Idle task. Is it not possible to use USB with a WFI Core sleep?Thanks for any insight. A forum search yielded mention of similar problems on other devices (over years!) but no defini...
I'm asking because I've done the steps shown in the screenshot. But, many libraries are missing!
Hello,I am trying make a USB device MSC.It works fine with SD card, but I want both SD card and flash.( I set max_lun to 1.)I have wrote the SPI_Flash_Write and SPI_Flash_Read that can be called by MAL_Write and MAL_Read.It seems work fine cause I c...
Hello ST, 1. ds12736 Rev.4 states in Table 24 that the abs. max. voltage on any pin is at least +4.0V (but this may be further limited by an injection current limitation) 2. ds12736 Rev.4 states in Note 4 on p.145: "Positive injection (when VIN > VDD...
Hello..I am using STM32F429 Disco Board in which I am trying to interface finger print sensor NB65210 of next biometric using spi and I need to read the finger print data I have a example code in which it is reading properly but it is not reading whe...
