A utility to temporary modify CPU and FSB clock settings for Sam440ep boards (all versions)

Author:

Max m3x Tretene, Soft3

What it does:

* it allows to temporary modify CPU and FSB clock settings. The new configuration to become active requires a soft reboot, and will be active until the next hardware reset (from the computer case button) or until the board is switched off. After that the board will boot again with the original clock settings.
This way it's possible to safely reboot the board in case a wrong clock setting was chosen.
* it's possible to over clock and under clock the board. Under clocking may be useful in case you need to run the board for a long time on a specific task which requires low CPU power, for example, allowing to save on electric energy consumption, and lowering the heat produced.
* it reports some useful information on the board, and may help to solve some misconfiguration problems

How to use:

* run the utility from WB, check if all the reported board informations are right, select a new clock configuration and click the "Set and reset" button.
The board will reboot to U-Boot, therefore close all active applications and save
all works before.

Notes:

* the 440ep clock setting is quite complex, it allows to create more than 500000 not
unique combinations of CPU, FSB, PCI and onboard peripherals frequencies.
Great care has been taken to choose only around 30 combinations which create working frequencies on the Sam440ep boards.
Not all the Sam440ep board models can reach the same CPU / FSB frequencies, and some boards can reach frequencies higher than others.
* Sam440ep mini-itx: this board wasn't designed with over clocking in mind, therefore
it's highly suggested to NOT select configurations with a FSB frequency higher than 133 MHz. Even better, select where possible, frequency around 120 MHz when
using CPU frequencies above 667 MHz, for example CPU = 733, FSB = 122.
* Sam440ep flex: can operate at higher FSB frequencies, up to 167 MHz, but reaching that limit depends on the actual DDR module used on the board.
* Sam440ep flex SE: same notes as the mini-itx model
* when over clocking, take care the CPU and all the board is well cooled, and run some
intensive tests before assuming the board is stable with the new settings. Running memtester alone is not enough to assume if a board is stable.

BIG FAT NOTE:

* There is the remote possibility that something may go wrong damaging your hardware. Use this tool with extreme caution and at your sole risk.
Please beware that every damage to the board due to incorrect settings or misuse of
this tool will not be covered by the board warranty.
