We are using STM32F469VI for developing a device which uses the following peripherals:GPIOUART (probably around 3 of them)SDIO (SD card in device, requiring FatFS access as well as mass storage via USB, see below)USB (2 ports)I2CWe would like to conf...
Hi all,we're planing to use an STM32H742 with external SDRAM (for data) and external Quad SPI flash.The Quad SPI flash shall hold the application binary - i.e. instructions, constants, etc. to be loaded at boot and all code to be executed.We'd like t...
Hi.I've been working on a project recently, and I've been having trouble with mounting an SD card. I've been getting FR_NOT_READY from f_mount function. Diving deeper into the code, I've found that SDMMC_GetCmdResp2 returns SDMMC_ERROR_CMD_RSP_TIMEOU...
Hi, I am using STM32G070KB controller. I tried to implement bootloader configuration via firmware as mentioned in document AN2606 and AN3155. But still its not entering boot mode. And also I need clarification for the "Execute BL_USART_Loop for USART...
Hello,I’m experiencing some difficulties trying to communicate with the embedded bootloader in SPI configuration.I have two separate Nucleo boards:- NUCLEO-H753ZI- NUCLEO-H743ZI2One of them is the master, the over is the slave (order ...
Googling around, this is unclear. The data suggests it is polled by USB code (using the ST library) for slave device presence (USB ID) but in my project I am not supporting OTG mode.The reason OTG is not supported is because a) you need to provide ad...
Hi, i like to start developing a medicine related product. And i am not quit sure whether to use the STM32 HAL-library or to develope it with the provided LL-library? I am not really expirenced in developing for medicine applications and all it regul...
Using IAR to develop software for and burn flash via USB on STM32 7B3I and Discovery eval boards.Need to develop my own Windows software to burn flash via USB on our own product.Am familiar with AN2606 [bootloader] and AN3156 [DFU] but neither appear...
Hello,I have a STM32L0x2 (M0+ core) project where, so far, I used to jump from the MCU app to my custom bootloader for updating the app in flash with a new program binary image, by setting flags in the backup registers and doing a SysReset.Now, that ...
