Hey everyone,I'm having trouble on my STM32WB55RG custom board.Using version 1.7 of the Cube FW package, my board worked properly. But one day, my device was not discoverable in Bluetooth (I suspected that I deleted it whith my custom bootloader, but...

Hello ST Community,Let's start with my problem:I have a STM32WB55CG chip that I want to get working in BLE. I also want it to have an USB CDC interface.I created a project on cubeMX, added my external oscillator (32MHz), activated the USB device unde...

Yes, what I meant in my previous message was that I don't wan to include a lot of files in my project, I'd like it to be the most simple possible.I tried to implement it at the very start of my application at 0x0800A000, but I had no success. How can...

Hey Remi,I just went to try your solution,but I quickly met a big problem:I cannot implementSHCI_C2_Reinit(); __SEV();in my bootloader, since I don't have the file shci.c in my project. I don't have the appe_Tl_init function or its contents either.So...

Hey Remi,SFSA = 0xCB (reminder: STM32WB55RG, with full stack)SBRV = 0x32C00Those are consistent.Just a reminder of what's really odd: when I compile the program at the address 0x0800A000 with bootloader at 0x0800000, Bluetooth stack doesn't work. If ...

Hey Remi,That's exactly what I did, SCB->VTOR is defined at 0x0800A000 in system_stm32wbxx.c, and navigated through Keil linker options to make it placed at the right address.My bootloader was developped for STM32F3, I then adapted it on STM32L4 and ...
