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...

Hi,I could use some help getting started with SPI5 (limited feature set). I want to operate as SPI master and send a single byte. I want to control SS manually as ordinary GPIO out.I've enabled the peripheral clock, and I can see in the debugger that...

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 ...

For those interested, here is the working code.

I agree with you that HAL might be useful for finding working examples, but the HAL code is terrible in terms of readability and ruins the understanding of the MCU by adding an intermediate layer. I want to master the MCU, not the HAL.Anyway, increas...
