STM32F091 how to detect suspected CPU stall through Flash access?

I'm having trouble with my IAP erase and write of Flash in my custom bootloader. I need to overlap comms activity with Flash erase so comms doesn't time out, but despite attempts to force the bootloader code, ISRs and vector table into SRAM, my suspi...

We are using STM32L476 in our application in which we have seen accidental change in RDP level when battery voltage drops below 0%. Is there any corner case we should take care?

In code, we do not have call for changing RDP but we have a logic to reset IWDG_STOP bit after wakeup from sleep mode. We are facing this option byte corruption problem when battery drops below 0%. (We do not have HW support for cutting off power for...

STM32G474 MCU port protection

Hi Folks,Greetings!At my end have a STM32G474 HRTIM output driving a MOSFET gate driver such as IR2110.In some weird cases encountered, when the MOSFET blows up, it takes away with it thegate driver as well.Not in all cases, but in some situations, I...

UART interrupt not working properly on STM32H753 MCU?

I am using STM32H753 MCU. I generated my code using STM32Cube. The UART is configured to work on interrupt, baud rate is 19200. I sent 'A' many time but most of the time I am receiving "C1" in hex instead of "41" ('A' in ASCII).When I analyzed the da...

Hi there, I already purchased a STM32H735 Board while trying to get a seat in the previous training. I don't need a 2nd one, but I would like to attend the online training...

My seat has been reallocated because I did not buy the board... what????

I wrote twice in here that I was going to get the board from mouser and infact I ordered the board just becasue of this webminar. I wrote it twice to be sure... and now I just received a message that my seat has been reassigned? what? is it supposed ...

Dear All I already informed you that I already have the STM32H735G-DK tools for the New STM32H72x/3x MCUs for running deeply embedded applications Online workshop information my email : d.frigerio@loptex.it

Facing difficulty to access internal bootloader in STM32H743BIT6

Hi Guys,I working on one project where we need to enter into system bootloader for updating new firmware through the UART from software without using BOOT0 Pin.But I am facing problem in entering bootloader through software(user application).I had c...

Write Backupcode from QSPi to SDRAM when flashing from IDE

My application is executed from flash and external SDRAM.I have a bootloader(seperat project) that saves the volatile SDRAM content on a QSPI.Normaly my application is applyed by a .hex file that is located on the SD-Card. So my bootloader can clearl...
