I'm testing a batch of 7 boards with an STM32F405RGT6. I'm trying to access the factory bootloader using an ESP32, which sets the boot0 pin to HIGH and RST to LOW and then sends the character 0x7F at 9600 bauds 8E1 (using pins PA09 and PA10). The pro...
When I hit Debug. System stops at first line of main() as intended. However no matter how I setup any breakpoints on the rest code, and hit Resume(F8) button. The code never stops on those breakpoint. even though I am 100% sure those breakpointed li...
I have been looking for a working project external loader in Keil or CubeIDEfor some of the discovery boards I haveThe only projects I see are in EWARMhttps://github.com/STMicroelectronics/stm32-external-loader I do not know why STM did this only in ...
Hello everyone, I am working with the STM32H7B3I-DK board and I need to establish wi-fi module. I am facing problems with the spi2 and usart2 communication. I saw in the documentation that these are two possible ways to communicate with wifi modules....
I want to initialize ov2640 camera using custom board with stm32h733VGT but camera does not respond to I2C as i check it by I2C function I2C device ready but it does not give ok in response but functions return ok if I attach it with any other senso...
Hello, I get the following error when I debug with blue pill. see the attached picture How can i fix that? thank you in advance
I have been trying to see how fast can I toggle the pins on STM32H7 MCU. I'm using a nucleo-H723zg board. the clock configs are at the highest (550Mhz for CPU, 275 for APB and AHB), the pins are configured as very high speed. But still with a simple ...
Hi All,I can not send data from the board to the PC via UART. I can see that USART2 can be used as virtual com. But, when send data from board to the PC, I can not see anything on serial port, I use TeraTerm, Putty, Hercules. I thought the new versio...
Previously i used to program and debug by using USB port for STM32H755 Nucleo-144.After i flashed the code with JTAG, i am not able to connect the board to PC and it is showing No target found. Is there any way of recovering it back.
how to find the programming manual or driver for the LCD screen on the board STM32H747I-DISCO?
