Hello, how are you! I am working with a project in the KEIL STM32756G_EVAL environment. Initially, the microprocessor was connected to an external 8 MHz clock generator, so the CAN bus operation was distorted. I purchased a 25 MHz quartz resonator and installed it on the Nucleo-F756ZG board. Removed the SB149 jumper and added two capacitors C37 and C38 (5.6 pF), and installed two SB8-SB9 jumpers that connect the quartz resonator to the microprocessor. After power was applied, the microprocessor started and began to correctly generate CAN bus signals. However, the Ethernet interface stopped working. Even the "ping 192.168.0.100" command does not work. So, I need help to fix the Ethernet problem.
