STM32F103 won't wake-up from standby mode using RTC alarm.
MCU wakes-up from standby mode by external signal on the wake-up pin (PA0). Also, the RTC alarm does produce an interrupt when NOT in standby mode (callback function does send some characters to UART). BUT, if the MCU is in standby it cannot wake-up ...
Help please, how to debug in SDRAM with IAR?
I am developing with stm32h750.My application is storaged in QSPI Flash and running in SDRAM.I use a bootloader to move image from QSPI Flash to SDRAM and jump to image.For downloading, i made a cmd line tool to communicate with bootloader via seria...
Known issues with D-cache and FMC on STM32F7
Hi,I'm using a STM32F765 clocked at 216MHz and when D-Cache is enabled it badly affects reads from a device connected via the external FMC address/data bus (NE1, 16 bit data, 10 bit address). The following pictures show the problem (note ringing is c...

Can software under the MCD-ST license be used in a GPL project?
Hi,I found some references about other licenses, but not much about this MCD-ST license,The problem here is `only for use within the Product'. In the licenceagreement restricts a `Product' to be one where the `LicensedSoftware' executes only on ST's...
Resolved! STM32G030F6 BOOT mode,
Hello, peterAnother question, about BOOT, I find that PA14-BOOT0, but if this MCU has 3 BOOT modes, it need 2 IOs to control, but I can't find the second IO, how can I set the BOOT mode? Or to debug, download firmware?Regards,Marvin
Identifying and solving UART error.
I am using a Nucleo GO70RB along with an ESP to control electrical appliances by sending commands to the ESP through the server and transmitting the said commands to STM32 using UART which is configured in normal DMA mode.I am able to control the app...
Resolved! What does the HAL_SAI_Receive() function take in as the parameter- 'Size'?
I am trying to use the HAL_SAI_Receive() function from the STMF767xx SAI drivers to receive some data from a device and I would like to know what does the 'Size' parameter actually represent. My scenario is as follows:1.) The SAI operates in slave m...
Resolved! Hard fault error when cast variable in stm32g070
I have migrated code from stm32f4 to stm32g0 suscesfully in almost all my aplication. However there is a part of code that rise a hard fault error. This is the code:crc_received = *((uint32_t*)&e22_uart_rx_buffer[(uint16_t)(e22_uart_rx_buffer_length ...
