Hi STM, I really need your help. I have been trying non stop for the past 5 days just to display something on the LCD.Step1: I am able to BLINK LD2, LD3 on the board. Step2: I want to display something on the LCD. But seems like it is always black. I...
It was working fine yesterday, today I cannot connect to the board. It is enumerated/identified but stm32cubeprogrammer connect fails. I tried different modes without luck. Now I am also trying with external debugger (jlink) (board powered by USB cha...
I would like to ask about the VAPP specifications.Until now, the connection was made via JTAG as shown below.There was no problem in writing.VAPPTMS_SWDIOTCK_SWCLKNRSTGNDCan I replace VAPP with VDD (pin 19) and feed power from ST-LINK?If I do, should...
Hi, I was using brand new Stlink V3 Set to program custom device with H7 onboard for 4-5 months. The programmer was connected with 3 lines: GND, SWCLK, SWDIO, and was working fine.Today, after weekend, I wanted to test new code. I had programmer conn...
As per datasheet of stm32u5 series during the Stop 1 mode DMA and peripherals are accessible. When tried to access the GPIO read. Controller during debug mode reading the GPIO, but in the run mode the GPIO is not getting read. How to read GPIO pin in...

Hello Team,We are planning to use the MCU STM32L496QGI6 for one of our products.The HSE we are using is ECS-480-10-37B2-RWN-TR (48MHz crystal) and the value of the load capacitor is 20pF.The board works well with HSI, but when we switched to HSE, eve...
I am trying to set the SECURITY bit on a STM32H7B3ZITX using STM32CubeProgrammer (v2.10.0). But it fails, see attached screenshot. I also tried setting the bit using the firmware. This does not produce any errors, but the bit is still not set. Follow...
I am using the STM32F407IGT6 chip. However, when I connected JTAG, the symptoms shown in the picture appear. So I have completed the VDD or continuity test. Can you tell me the circuit diagram and the reason?
Hello,There are 3 lines of hardware development tools (quite a lot of products):Nucleo boardsSTM32 discovery kitsSTM32 eval boardsFor prototyping of my HW concept I want to use one of ST boards (essentially uC) to control my custom stuff.The ST board...
