I'm using a NUCLEO-L4A6ZG board with the STM32L4A6ZG MCU. My project uses the microSD connector for serial communication with a computerThe microSD connector uses lpuart1. I use uart_irq_callback_user_data_set to install a callback for received data....
Apparently I can not easily update my application firmware for stm32F746 toughGFX app with just one Bin file. I have written a bootloader for an SD card. It loads firmware at 0x08040000. I am not sure I understand everything that is going on here, so...
I'm working on a custom board using an STM32H743IIT6. In general, the board is working, but I'm running into an issue with the RTC. The RTC is running accurately, but when I reset the board, the RTC resets. This happens even if I just terminate and r...
Hello,I’m using the STM32H747. When I set the RCC power source to RCC → Power parameters → Supply source = LDO, the core locks up; if I select SMPS, there’s no issue.When I set CM7 to its maximum clock frequency (480 MHz) and CM4 to 240 MHz, the tool...
Greetings, I am using a STM32U585 MCU and I made a custom made code that implements the DFU protocol. I could successfully flash a firmare through .bin file and set the Option Bytes, set RDP level 1 and go back to RDP level 0. What I want to do is to...
Hi,I have a STM32F411CEU6 Blackpill that I'm wanting to interface to an eMMC (Raspikey to be exact via SD/MMC reader) with FATFS. I have confirmed that the connections with the SD/MMC reader are fine with a read/write test to an SD card in a differen...
I have a design that I have used in the past but a latest build I am having trouble with the system clock. I am using 8mhz crystal, IOC file HSE is setup to use the crystal. I cannot get the processor to run above 16 Mhz. I have older projects that u...
Hi We are working on a project based on the STM32U073CCT6. The USB interfaces is not need. How should I connect the VDDUSB pin in order to minimize tthe power consuption? Is it Ok to connect it do GND? BrGilberto
I tested FMC speed on F403 and H743. F403 works fine but H743 code will stopped due to memory fault.I set FMC parameter like belowMy plan is to connect stm32 to fpga by using FMC so did this test to check the speed. F407 test succeeded.But H743, the ...
I tried to set readout protection via ST-LINK CLI - it's enabled and disabled correctly, but after RDP=0 I can't erase/write chip - I've got an error on write operation. Tested on 2 boards and both boards have same behavior. e:\STM32 projects>"%PROGR...
