The "Introduction to secure firmware install (SFI) for STM32 MCUs" AN4992 does not list the H743 as a supported device.The Secure Programming tab of the latest Cube Programmer V2-18-0 (Jan 20205) states it only supports STM32U0-5 & WBA.Yet the SFI/S...

I've read the X-CUBE-SBSFU Secure Boot and Secure Firmware documents and it doesn't explain if these are tools, with GUI, or just an API, which should really be explained at the start.If you know all about it I am sure these documents are just great,...

Are there any issue using both controllers in host mode? USBH_StatusTypeDef USBH_LL_Init(USBH_HandleTypeDef *phost) { /* Init USB_IP */ if (phost->id == HOST_FS) { /* Link the driver to the stack. */ hhcd_USB_OTG_FS.pData = phost; phost...

The Escape key was mapped to 0x00 in the USB HID code, I added it and it works fine but I'm curious to know why it was absent? Bug/oversight, another method used for Escape key detection? #ifdef QWERTY_KEYBOARD static const uint8_t HID_KEYBRD_Ke...

The 32C071 has the standard Synopsis USB controller (1x) like STM32F4/7 and H7 which have a dual USB, so you will be able to drop in the standard driver, it takes a while to go through the code, but its not too difficult. If CubeIDE won't let you ad...

Expensive "magic" hardware is not needed for the secure encryption of a binary file, its just a dishonest marketing ploy, the STM32H753VIT6 is TRIPLE the cost of the 743 version on Digikey at 100+ quantities.Microsoft forced people to pay $300 a ques...

Come off it Pavel what you're saying is nonsense, STM are just forcing H74X users to change MCU on the pathetic excuse of missing hardware security features in their more expensive MCUs.You're going to tell me that the 480 MHz Cortex-M7 can't run a d...

You missed the point totally.Does Visual Studio or Web applications force users to write the same code, all of them, to install a security certificate? No. Why not, they can right?! Well, because it would force tens of thousands of developers to writ...
