Resolved! Problems programming/starting debug session with custom tables at end of Flash (STM32H563)
Hello,I am working with an STM32H563VITx (2 MB Flash) and I am experiencing a repeatable issue when placing two custom sections (.param_defaults and .app_defaults) at the end of Flash.The application runs as long as these sections are removed.But wh...
MIPI Camera on STM32N6
Hi everyone,I'm working on a project with an AR0144 image sensor connected to CSI2. (STM32N6)I have a question: if I use PIPE0 without any ISP processing of ROW10 data from the sensor to memory, do I still need to use ISP?Do I need to initialize it? ...
how to jump to system booltloader from app code without change boot0 to high
Hi All,MCU is STM32H563. I attempted to jump from the Secure App directly to the System Bootloader so that I could program the OBK file without pulling BOOT0 high.However, using the method below, the jump never succeeds — the MCU keeps resetting cont...
PCROP, End-user usage example
Hello,I have already read the AN4758 application note and I still have a few questions regarding PCROP.I have a project for end-users where the main application provides functions (API) that users can call to develop their own code. I was originally ...
STM32N6 is only flashable after POR
Hi,We have a weired problem with a custom N657 design.When using the Nucleo board, its possible to flash the program on the external flash, as long as BOOT1=1.The programmer resets the board and it flashes the firmware normally every time.On our boar...
Resolved! I make a boot on stm32f103, after I enable __enable_irq(); then hang
I want to make a project on stm32f103, I write some code. When I want to add sd card support, I need to use spi interrrupt enable.But after I enable the global irq then the code is hang. Besides I debug the code with gdb, then I do ctrl + c , then I ...
MIPI：Failed to read the ID of Driver IC
I'm trying to read the ID of ST7701SN with STM32F469. The read command was sent correctly by the MCU. But the voltage of the response by the ST7701SN is too low. Could it be caused by the settings of the MCU? I tried different screens but it's always...
Zephyr application gets stuck after enabling MCO1 on stm32n657X0
I'm using zephyr sysbuild approach to get mcuboot along with the application (application runs in XIP mode)I see that application proceeds to some point; I presume to the point where I enable MCO LL_RCC_EnableMCO(LL_RCC_MCO1)And then it gets stuck, s...
STM32L4R5ZIT6P ESD Damage
Hello, I may have accidently either shorted or applied voltage to my UART TX and RX pins on my MCU which is on a custom PCB and now my PCB is pulling +60 mA of current under load. I am now experiencing difficulty programming the chip and I am gettin...
