STM32H723 PTP IEEE 1588V2 support

I am currently using STM32H723 MCU for a project. I want to use PTP to synchronise different peripherals that will send data and their timings need to be precisely synchronised. The reference manual has got a whole section for programming IEEE 1588 t...

Bootloader/BootROM Cannot Execute App Code on SDRAM Address

Hello,I am currently working on a bootloader code. I successfully managed to execute the app code by copying to the RAM address (0x20000000). However, whenever I try to copy the app code to SDRAM (0xC0000000) instead of RAM, bootloader never executes...
