Wrong Comment in AN2606 (Rev 42) in Table 130 for STM32L552 and CAN Bootloader

There is a wrong comment in AN2606 (Rev 42) in Table 130 for STM32L552 and CAN BootloaderThe Comment for FDCAN bootloader tells:USB FS configured in forced devicemode.USB FS interrupt vector is enabled andused for USB DFU communications.Note: VDDUSB ...

I use STM32L0 series board so here we have to design code for UART Bootloader for FOTA i tried some possibilities following datasheet (AN2606 Application) process but i didn't get result so please send me some example code.I am waiting for your reply.

Please support me to complete this task.------------------------------------------------------------------------------Thanks & Regardsswapnil Maskar.M:9767067210

Is there any example of use for the HS and FS ports independently with the use of RTOS, or without the use of RTOS?

I tried to use the two ports independently, the USB HS with a pendrive (MSC) and the USB FS with a keyboard (HID), but I couldn't.It only works if the ports are treated in sequence, but not in parallel.From what I could see, the HAL libraries are sha...

USART1 ST bootloader not working on Nucleo F070RB

USART1 works as expected from firmware loaded via SWD. However the ST bootloader does not work. It never responds to the initial 0x7F with anything. I have scoped tx and rx and cannot see anything wrong and, as stated above, the UART works under the ...

STM32L452 bootloader reset by PA0

Hello,I believe I have a rather curious situation. I was able to jump to the device embedded boot-loader (USB) which works nicely. However if button connected to PA0 is pressed (rising edge), the boot-loader reboots to main code. Pin PA0 is previousl...

Cheapest STM32 that can simultaneously do USB as a Host and Device.

Hey all! Does anyone know the cheapest option for a STM32 chip that can simultaneously do USB as a Host and as a Device? I tried using the product selector but the issue is that it didn't list price as a filter option, so I thought I would ask here.I...

STM32F429 hardfaults in __libc_init_array after jumping to application's Reset_Handler from bootloader. Why?

I’m creating a custom USB HS DFU bootloader for my STM32F429 project, using arm-none-eabi-gcc together with the CLion IDE. I’m having trouble jumping to the application code from the bootloader.The CLion project consists of a bootloader target and a ...
