Re: STM32F103C8 128K - USB unknow

Which board are you using ? when you upload via st flasher do you reset the boot pins so it boots the new code(board dependent) ? is the st flash still connected when you repower the device and plug to usb ? we will need a bit more info about your device, setup initial code , sequence of operation e...

Re: Has anyone got a STM32F411CE Blackpill working as a USB Host?

I think you need to look into the stm32f4xx examples packs available from STM website or git hub, heres a old github example , note that bugs and api changes by stm to the stmcore renders some example code non-compilable so you may have to hunt down a older stm32core or patch to newer api/core https...

Re: Problem getting CAN to work on STM32F767

This is a big amount of things to check and test, thanks.It will take some time. First I have to find PB12 and PB13 for measure the blinking. However, this seems to be another interface as described in https://github.com/stm32duino/Arduino_Core_STM32/blob/main/system/Drivers/STM32F7xx_HAL_Driver/Sr...

Re: STM32F0 Bootloader Problem/Issue

if you compile the arduino bootloader for your device and flash it via stmcube then you can use the arduino environment to re-program with new code without using the boot pin method and stmcube. i dont use the arduino ide myself so i cannot 100% tell you what menu option you must choose to flash via...

Re: Problem getting CAN to work on STM32F767

one final note, pay attention to what written in this message https://www.stm32duino.com/viewtopic.php?p=2153#p2153 So I conclude that the bootstrap loader, when it jumps to the application program, does not shut off the USB, and this must have been done in the core you may also have this issue depe...

Re: Problem getting CAN to work on STM32F767

If you are not using arduino and are using stm32 cube then this code should init without error, main.c uint8_t ubKeyNumber = 0x0; CAN_HandleTypeDef CanHandle; CAN_TxHeaderTypeDef TxHeader; CAN_RxHeaderTypeDef RxHeader; uint8_t TxData[8]; uint8_t RxData[8]; uint32_t TxMailbox; static void CAN_Config(...

Re: Problem getting CAN to work on STM32F767

Hi, hope this is the right spot to post this problem. I am trying to get CAN working on a custom board with a STM32F767. However, I am completely stuck and there is no progress anymore with try and error. Since the code of the project is not open, I am not able to share the whole project but I am a...

Re: Jump to bootloader STM32F103

Implementing a serial bootloader and bootloader check , the best way to do this is have them as two parts, bootloader/program and maintain as such. In the bootloader you need to decide on your check, You can look for a single magic value in the memory , bear in mind you could possibly end in boot lo...

Re: [Solved] Can I use SPI2 with Uno/Nano Library that uses SPI?

Hi, When you say it worked on 5-6 programs , I assume you mean the board accepted 5 - different .bin files and flashed them and they booted (be it blink or what ever) but when you upload your code it wont function, I assume then yes there is a conflict, i would start by putting serial.print right at...

Re: [Solved] Can I use SPI2 with Uno/Nano Library that uses SPI?

The USB boot loader need to be flashed first and at a different location of memory, e.g bootloader start address 0x0000000 user code start address 0x00005000 also depending on which ide you are using you will have to change programming type. i use platformio and Black Magic probe( the stm32 jatg sof...
