Hi,I am not able to get a correct reading from ADC1 INP0 (PA0). All the other analog channels works fine.The datasheet mentions this:ADC option register (ADC_OR), option bit 0 (OP0)For ADC1:0: INP0/INN1 GPIO switch control disabled1: INP0/INN1 GPIO s...

I've noticed some strange behavior when doing sector erase on this device.I erase sector 0..63 on bank 2 and write my data. I can confirm that this operation is correct by reading the flash starting on 0x08080000 using stm32cubeprogrammer.As a verifi...

Based on the information found in AN4286 rev 14, I am trying to command to bootloader to start executing the application.The setup is a H573 and a H563 connected over SPI @ 0.5 MHz. The 573 operates as SPI master, and the 563 as a slave. I know that ...

Hi,in AN2606 rev 64, I cannot find the SPI settings for STM32H563 bootloader, i e CPOL, CPHA etc. For the other MCU:s in this document, this information is provided.For example H72xxx comes with CPOL = CPHA = low.Using these settings, and a rather sl...

Hi,using the code below, the device will not run when set to 250 MHz (PLL1DIVR = 99). It works fine at 200 MHz, and slightly above.HSE is a 25 MHz crystal.What am I missing? static void SystemClockConfig(void){// Must set Vcore to max before we can r...

Though I doubt this is related to the external HW, please see attached file.The schematic consists of multiple pages that I can not share. To the right you see the LP-filter mentioned above (2k + cap). This is connected to PA0, though not on this pag...

It is a custom board.

I am usually very satisfied with ST's hardware and documentation, but getting the bootloader in the STM32H563 to work over SPI was quite a miserable experience.Here I have summarized my experiences and attached working code to communicate with the bo...

Hi,please see my active post where I try to follow AN4286. It "almost" works, so I guess I miss some little detail. https://community.st.com/t5/stm32-mcus-products/stm32h563-bootloader-command-over-spi/m-p/731973

Thanks for the fast response. I've been playing around with the synchronize message, and it seems to me that it takes repeated attempts before I get an acknowledge. It often takes around 10 attempts of sending 5A + sync before I get the ack. Is this ...
