Hello, i am trying to use system bootloader in STM32F411 for software update via USB. I use a freertos in my project.Workflow is here: By sending a "BOOT" via Virtual Com Port USB, MCU executes folowing code: SpoilerUSBD_Stop(&hUsbDeviceFS);uint32_t ...
I’m using an STM32 microcontroller and am trying to understand more about the flash memory endurance cycles. The datasheet mentions an endurance of 1 kcycle (1,000 program/erase cycles). I think possible Write and read (1000 cycles ) or is there any...
Good day everyone,I am currently implementing an update process and I am facing some issues if I want to erase the internal flash memory sector if my code is running from an external OSPI-Flash. I am getting the errors:Read Protection ErrorRead Secur...
Hello everyone,i am trying to read the device unique id of my stm32h7b3 mcu, but get a bus fault on line 2: uint8_t* uid_base = (uint8_t*) 0x08FFF800; uint8_t i = uid_base[0]; Do you know what could be the problem ?
Hello,I am building and application with a STM32U575 and a 4Gb NAND Flash. What I am trying to achieve now is to upload files from my PC through USB and then used these file within the STM32 using FileX.I already managed to set up FileX and LevelX to...
Hi All,I have interfaced Winbond W25Q128 external flash and IS42S32400F-7TL external RAM to STM32H750IBK micro on my custom board. I have found an external loader file (stldr) for my pin configuration from a community member.I can program, read and ...
I am looking at strategies for updating flash over CAN for the F446 (STM32F446RET6). A small loader program resides in addresses 0-0x8000, and loads the addresses above 0x8000 while there is other CAN traffic running. (This has been done and works wi...
Hi @Tesla DeLorean ,I use the IS25LX064 OctoSPI Flash memory with the STM32H573 and i can write and read from memory using direct mode. In memory mapped mode i can read the flash correctly for 0x90000000 but writing at 0x90000000 using memory mapped ...
TLDR: application tried to write to a FLASH address without accessing FLASH peripheral, so the Flash bit CFGBSY in the SR register got set and further accesses to FLASH CR register leads to a Bus Error (not documented). Of course, the main action is ...
... leads to "funny" results:STM32L011 with 16 kB of flash, HAL inits and LED toggle in main, DEBUG, no optimization:93% of flash usedI had not expected it to be that bad! Okay, I will probably not use too much HAL, will use Release version with opti...
