My question might sound "strange" for HW experts.My STM32U5A5 MCU has DCache (16KByte). Datasheet says: used when external memory is connected (e.g. NAND/NOR flash, OCTOSPI).DCache is not used for internal memory (when running from MCU flash or inter...
It has been asked several times, however I can not find a working solution for me.With STM32L486RGT6 I achieved to implement jump to bootloader, entering DFU mode successfully. All fine!Doing it similar for STM32L071CZY6TR and STM32F469VE it does not...
What I want to do is send Write Enable instruction to external Flash and erase.The environment is as follows.Use Board : nucleo l4r5ziIDE : Atollic TrueSTUDIO® for STM32, Built on Eclipse Neon.1a.(Version: 9.3.0)FLASH : W25Q64JVThe connection diagram...
Hello.We are trying to read measured voltage by MAX17201 chip - register 0x09.But we are receiving incorrect value - 0x936A when battery voltage is 3.0V?!We are using I2C communication protocol.Here is the I2C initialization:static void MX_I2C1_Init(...
My project use STM32U595 chip. It will use HS USB to send large amount data to computer.I use NUCLEO-U5A5ZJ-Q for testing.The project use Ux_Device_CDC_ACM in NUCLEO-U5A5ZJ-Q of STM32Cube_FW_U5_V1.4.0.I reference this post https://community.st.com/t5...
Hello tinkerer,i am working with the Stm32Wb55 and trying to send data via Bluetooth, unfortunately when i run or debugg my code, most of the time i lose after 30 seconds the connection because the GATT procedure issues a timeout. In terms of the rea...

Hello all,this code snippet is not working: the page is not erased, although the HAL does not report errors.No RTOS is running. if (HAL_ICACHE_Disable() != HAL_OK) {Error_Handler();} status = HAL_FLASH_Unlock();if (status != HAL_OK) {Error_Handler();...
I am not new in using STM32H7 products but in my last project I can not connect the target by ST_Link.I take care about power supply, pins to connect at GND or 3V3 and so on but the Link-Utility return this error:<<08:28:41 : ST-LINK SN : 44003200150...
Posted on June 07, 2017 at 11:16I am at my first time with RTC and I have some problems.I would like to configure rtc as a calendar.I would like to retrieve date and time after a certain event.I am following the RTC_Calendar example in the STM324xG_...
