Rev V system boot loader FDCANSTM introduces boot via FDCAN1 with chip revision V.The system boot loader version ischanged form V13.3 to V9.0. I’ve tried to figure out how does it work. Here are my findings- AN2606 rev 38 is updated. It describes...
I found an example using a STM32F103C8T6 to get three VCPs, so I assume it's possible to get more. Can I get an MCU that will support four? With an F0, can many can I get? Two?
Hello Everybody,I am trying to get the USB CDC device only with VBUS sensing to work. Sadly I get allways the device descriptor request error (Error 43) nd the device won't enumerate with my PC host.Most possible solutions or discussion about this pr...
I'm porting some fully functional older CMSIS firmware to STMCube and TrueStudio. The old report is 363 bytes which compiles, but Windows Device Manager detects an error in the Report Descriptor. After some tinkering, setting USBD_CUSTOM_HID_REPORT_D...
Hello everyone! I'm working on a project like Audio Playback. I have tried compile and run Audio_playback_and_record from ST's Firmware pack its working good.I'm trying create my own project file, i'm stuck in read wave data from usb. I can get wavef...
Refer to AN2606 p. 260 - 263There it says, that for STM32L43xxx derivatives CAN1 bootloader is mapped to PB8 pin (RX) and PB9 pin (TX). My derivative supports CAN but doesn't have these pins, because of a 32 Pin package. Is there a possibility to use...
Hello,I've been using the NUCLEO-L476RG board for development. Now I want to design my own PCB with the same component. My question is about the JTAG port - in the NUCLEO board it is implemented as a USB connector but they used an additional uC for t...
Hello Folks, Is there a list of mcus (STM32LXXX) that support the boot modes over USB port?
Hey.Im using adc dma to transfer data from adc to memory. After each sequence of conversion I need an interrupt.My first question is that is using dma in my case something useless?My second question is that after adc sequence of conversion interrupt ...
I'm using STM32F103C8 and I have Bootloader at the start of flash 0x08000000 and Application start at 0x08008000. On powerup Bootloader start to perform basic functions and then jumps to the main application. Everything works fine but what about Boot...
