change am335x frequency to 26 Mhz

Thanks Biser,

but the custom board i received doesn't have these pins.

Can I change this frequency by hardcoding in the code of u-boot ?

I think I asked the wrong question, sorry for that. I will try to explain. My employer gave me the custom board. It has Windows running but i have to try to get u-boot and linux to run on it. The cpu is am3354 and It has a main frequency set at 26 Mhz. I tried to debug it using a serial port but they told me I have to:

1) alter the frequency in the u-boot code because the evm code i was using, uses a frequency of 24 Mhz.

2) add ddr3 support , i have another post for that so ignore this for now :).

3) and finally change the pins but they would give me the header file containing the right pinmux.

So I don't think I have to change the hardware settings. I hope this better clarifies my initial question.

Is it correct that changing the external xtal (24MHz to 26MHz) and changing the SYSBOOT resistor for this, you don't need to change anything in de firmware because the multiplier uses the SYSBOOT values to get the correct end frequency ?

PS : I want to go the otherway, we are running on 26MHz hardware but would like to test an OS that was build for a 24MHz xtal ?
