Hi All,I have a strange problem entering the Bootloader.I need to send 0x7F twice to enter Bootloader. Details: I am working on a project where I need to program STM32H743xx MCU via UART pins. I was successful in programming STM32H743xx “Version Y�? ...

Hi Everyone,I am working on a project where I need to program STM32H743xx MCU through UART, but I am facing problem in entering the internal bootloader through software. I have created a .s file to enter the bootloader where I need to wait for a firm...

Hi,I have been working with STM ADC’s from quite a long time. I had used STM32F373 and F4 series MCU ADC’s earlier for my applications. As, now my application requires huge amount of RAM, memory and computation speed I have shifted to STM32H743 MCU ....

Yes, I checked the revised version of AN2606 and they have mentioned about the synchronization bytes. But in the earlier version of AN2606 , this behavior wasn’t mentioned.Yes that’s true this behavior has to be clearly mentioned in the document in o...

Hai Amel,Thank you very much for responding to my post.Unfortunately the USART1 pins happens to be PB14/PB15 in my case. I had a formal discussion with ST FAE and tested both Nucleo board's with Version V & Y series MCU. From the test's we concluded ...

Hi Clive,Thank you very much for your reply. I don’t want to use reset handeler to enter Bootload mode, I need to use interrupt mode to enter bootload, Is there any other method to unwind the callback as even after disabling the DMA stream it is not ...

Hi AVa Tar, Thank you very much for your reply. I checked the stability of the power supply it is quite stable and even I have bypass capacitor banks on PCB and it’s a 4 layer PCB so the power supply should be good.My application needs around 10K ban...

Hi Khouloud,Thank you very much for your reply. In STM32F373 MCU I was using 16 bit SDADC (Sigma Delta) and even for 16 bit ADC the noise was around 4 LSB.But now when I compare the results of 12bit and 16bit ADC of STM32H743 it seems that there is j...
