Hareesh: For some reason on F280049 ControlCard, using the external oscillator and resulting SYSCLK as source for CAN did not work, BUT if I sourced external oscillator directly to the CAN, it did work - came up and ran without any problems. This was highly unusual, because I also have an F2837x ControlCard, and CAN will work with both external oscillator as direct connection and using SYSCLK, with SYSCLK being sourced from external oscillator. Do you know of any reasons why the F280049 ControlCard needed CAN to be sourced directly from the external oscillator?
