XFLASH Message?

[AudioBoy]

I try to burn my .xe file into my own board, and I got some warnings:

Hi Audio Boy,

Warning: XN11135 Attribute SystemFrequency is ignored when Oscillator is not specified - In your XN file you have specificed a SystemFrequency attribute but not an Oscillator attribute. The SystemFrequency is effectively useless without a corresponding Oscillator attribute and therefore will be ignored. In this instance the tools will not program the pll on your device and the device will run at the frequencies determined by your oscillator/boot mode pins.

Warning: F03098 Factory image and boot loader cannot be write-protected on flash device on node "0" - This is to let you know that the spi device you are using does not offer any write protection. This means that your bootloader and factory image could be over-written either accidentally or maliciously and your device would not boot.

Best Regards,

Colin.

Thank you, Colin.
I understood.

I used 13MHz oscillator and mode0=mode1=0;
SystemFrequency was set to 500MHz and all works.
Now I put "Oscillator=13MHz" into my .xn file, everything works and no warnings.
