Resolved! STM32L486VGT6 - Port mapping during Bootloader state
Hello everyone,In my project, I am using the STM32L486VGT6 microcontroller to manage several hardware peripherals. Additionally, I plan to utilize the bootloader feature to flash the code via the USBFS interface.As we know, when the MCU enters bootlo...
STM32H7 PCx_C pins unusable for boundary scan?
Hello,I used CubeMX for a design for H75x in LQFP176.I was able to configure SDCKE0+SDNE0 signals of SDRAM Bank 1 to PC2_C and PC3_C.Now I wanted to configure a SDRAM test using JTAG boundary scan but the JTAG tool manufacturer claims that these PCx_...
What's the correct way to configure the STM32H7 to count pulses using an external trigger?
I’m attempting to configure TIM3 to count up on pulses received from an external trigger on TIM3CH1 but I'm not seeing CNT change.I’ve followed the sample instructions in the datasheet (RM3099 Rev 3) (for External clock source mode 2--all registers m...
