I've been using an STM32G474xx in a project for a few years now and have a function that jumps to the bootloader. It seems in a recent rev of the chip the bootloader has changed. I'm finding that I can no longer jump to the bootloader similar to how ...
In my project I use FDCAN1 and FDCAN2 for communication.At startup of the system CAN1 ist used to send out messages with 500 kBit - CAN2 is used to receive data at 1 MBit and this works. Now the user can reconfigure the CAN busses e.g. as follows:Rec...
I have tried to migrate an STM32CubeMX project from the STM32H747AIIx to the STM32H747XIHx using the procedure described here:How to switch from one STM32 to another using STM3... - STMicroelectronics CommunityIt failed with the following error messa...
Can anyone help me with debounce code in C for Rising and falling edge interrupt??
Hi everyone,I’m testing a 32Mb serial QUAD SPI RAM (ISSI – ISS66WVS4M8) with the nucleo – H723ZG development board.It works fine if I use all the QUAD SPI commands but my need is to use it in memory mapped mode.When i use the memory mapped mode confi...
Hello, I have a DMA stream working in Normal mode (Mem to Peripheral). This by itself is working properly (without MDMA). I want to configure MDMA to set the next parameters for the DMA to handle. I configure 4 words (4 uint_32) in memory for writing...
Hi, I wanted to clock my timer output using LSE crystal, but unfortunately only tim2 is supported with this feature. But then I saw an option of LSCO as output in cubemx, this enables the pin on MCU and according to documentation this output LSE cloc...
Hello,I am currently developing a Bootloader for a STM32H562. The Bootloader checks, if there is a valid application present by calculating a checksum over the application area. To avoid getting ECC errors during the checksum calculation, I disable t...
Those are the setting for STM32H7A3IIT6Q ? (there is AN5050 where they show but DMA setting only)I am trying to useHAL_OSPI_Transmit_DMA(&hospi2, aTxBuffer)(I have this chip working in interrupt mode fine , HAL_OSPI_Transmit_IT(&hospi2, aTxBuffer) b...
Heyho,I'm currently working on an ethernet bootloader, I have it all working now.File upload via browser using http POST, into HyperRAM (~200 ms for 400kB bin file),from HyperRAM to external SPI flash (for now octal on H735-Discovery, later changed t...
