STM32F334 TrueStudio - Adding libarm_cortexM4lf_math.a Getting error: arm-atollic-eabi/bin/ld.exe: <WWDG_EXAMPLE>.elf section `.rodata' will not fit in region `FLASH' and region `FLASH' overflowed by 101180 byte

The size looks like around 107KB of libarm_cortexM4lf_math.a library, the total flash is 64KB in STM32F334x SoC. Could you let me know if I want to perform FFT (Fast Fourier Transformation), is there any alternative or light weight library I can use....

STM32H7xx - Bug in SPI Driver HAL in larger transmission (32 bytes transmission in one call)

Hi all. I am having an issue with HAL_SPI_TransmitReceive routine under STM32H743. I am using STM32CubeIDE ver 1.10.1. In our setup for STM32H743, it is bare metal (no RTOS). The SPI is in Slave mode. In particular, I am using SPI4 as follows:Mode: S...

Please can you check the attached photo, Taiwan parts with different gate mark with Philippines, and at the bottom of the gate mark, Taiwan part with 03, can you please advise what it stands for?The Philippines gate mark changed the direction and wit...

STM32L4A6ZG boundary scan has stuck inputs every 24 cells

Our design has a STM32L4A6ZG, we are using our own boundary scan tool to test the PCB. During testing we found that input of PF1 (cell 375) and PD13 (cell 207) where always high after some more investigation it looks like the inputs that are 24 cell...

Initialize SDRAM in SystemInit

Hello,I am using a STM32H7A3 and a SDRAM MT48LC8M16A2P.In a project using the emWin graphic library, I would want to store the relative buffer 'aMemory' in SDRAM.By reading on community and seeing the examples I understood that I have to write a Syst...
