Setting oscillator frequency config to 19.2 MGHz of Beaglebone Black

Hello,

I am trying to set oscillation configuration of beaglebone black to 19.2 MGHZ.

I tried to set Sysboot 14 [Pin31 to low] and Sysboot 15 [Pin32 to low which is by default].
If I do this then its not booting.

If I wait till SYS_RESETn to become high after power ON and then make Sysboot 14 pin low, then it work at 24 MGHZ.

Is there anyway to set oscillation configuration of beaglebone black to 19.2 MGHZ?

Regards,
Sachin V

Only way to do this is to replace the 24MHz crystal with a 19.2MHZ crystal. The boot pins only tell the boot code what the crystal frequency is.
