Research direction
Start with the timer example documentation at the linked NuttX character-timer page and the menuconfig steps for the Nucleo-H743ZI2. Compare the selected STM32 peripheral-timer configuration with the running system's /dev contents and the Failed to open /dev/timer0: 2 error. Done means the example can access the expected timer device, or the documentation clearly explains the required configuration.

Description
Hello! I am trying to run the timer example following the steps provided here: https://nuttx.apache.org/docs/latest/components/drivers/character/timer.html
The few things that I do that I do not see in the steps, is also selecting a peripheral timer, from the STM32 peripheral tag.
I get the error Failed to open /dev/timer0: 2 when running the example. A quick ls of the /dev shows the following:
console
null
ttyS0
Why isnt /dev/timer0 part of this list.
++ I am using a Nucleo-H743ZI2 board with pretty much nothing else running other than the simple timer example. From the link provided i followed the second set of steps via the menuconfig
