Hello, I am trying to reduce time lost troubleshooting delay errors on boards where `CONFIG_BOARD_LOOPSPERMSEC` is left undefined. I have removed the default value to encourage users to either use a different delay implementation or run `calib_udelay` on their board to get a proper value for their system.
The PR (https://github.com/apache/nuttx/pull/17011) is ready to be merged aside from existing configurations in mainline where boards relied on the default value for LOOPSPERMSEC (bad). If you own one or more of the following boards, could you please run ` calib_udelay <https://nuttx.apache.org/docs/latest/applications/examples/calib_udelay/index.html>` to get an appropriate value for `CONFIG_BOARD_LOOPSPERMSEC` and let me know what that value is? I will update the configurations for that board so that the mainline no longer has incomplete implementations. The boards are: fvp-v84-aarch32/fvp-armv8r-aarch32 mps/mps2-an500 mps/mps2-an521 mps/mps3-an547 phy62xx/phy6222 stm32wl5/nucleo-wl55jc tms570/tms570ls31x-usb-kit stm32/nucleo-g474re stm32/b-g474e-dpow1 fvp-v8r/fvp-armv8r imx8/imx8qm-mek a527/avaota-a1 Thank you, Matteo
