Lines 19 and 26 are repeated. Mode is set to normal (0x0000) twice. The structure is already initialized to `={0};` it doesn't need to be overwritten once, let alone twice.Initialized for STM32H563.usart.c /* GPDMA1_REQUEST_USART1_TX Init */ DMA...

I'm trying to set up a DMA transfer from UART1 periheral to memory. Using LL drivers. Using STM32Cube for "convenient" setup. It puts the all the USART peripheral init in usart.c. Where for GPDMA it does something like: /* GPDMA1_REQUEST_USART1_R...

It's a niche application. STM32H5 QFNI need SPI2_MOSI to make a specifically shaped wave. SPI is works well for this. I do not need the SPI_CLK pin/function. I set Cube MX to SPI2 Transmit Only Master, and of course it applies the CLK pin because alm...

Here is my attempt at background as I understand it... iROT is a ROM program in the STM32H563. It contains a P256 EC algorithm, and checks some section of FLASH that you define as a program for a signature, then jumps to it. The definition of the pro...

I'm migrating from an F4. So this is all new to me. Need help getting started. I currently have: A primary bootloader. It checks the application flash for a stored signature every bootAn application flash. It's up to 896KB.2MB Flash, two banks for fl...

The GP1DMA UART for U5/H5 works using linked lists for chaining transfers. Many (most) of the time you would want one transfer repeated over and over. Like UART downloading to a single circular buffer over and over.The default instance for MX setup ...

Thanks for the time it took to answer but that is not helpful. If I could easily test this, I would. It will be a couple weeks until I can get a development unit in hand, and I'd like to try and make plans for the layout. Perhaps someone else can ans...

First I'm not answering depending on the number of parts you buy. I just try to help on my spare time.Secondly, STiROT is supposed to be used with 2 slots, and was certified in this configuration.I appreciate your help. It was more the ridiculous not...

It it checking a magic at first address of the slot. Now, if you need to reuse this slot for other purpose, you should first check that STiROT does not corrupt your data.STiROT code is not public so I cannot tell 100% what will happen. @Jocelyn RICAR...

@Jocelyn RICARD 1. I can't seem to find where that "trigger" mechanism is for iROT to look for an install an update. Magic value at the download location? Is it OK if I co-exist this area with another download area, and put something there that is no...

CubeMX setting GPDMA1 in UART repeats init members

STM32H5 DMA (GPDMA), why is USART using a "node"? Intent?

I need to use SPI without a clock, Cube MX won't let me do it.
