Megadrum's no responding

[km500]

Earlier,
I had a Firmware ver 20100827

Then i updated it according instruction described in forum.


1. So your comment means that I did something wrong during updating ?
2. Can I repair everything during new updating ?
3. Upgrading new firmware will remove all firmavare existing in my megadrum ?
4. “…set it manually to match crystal frequency….” You mean new updating or some changes in megadrum options done mannualy ?

Changes in version 20120415:

2. Some people reported Atmega crystal frequency is not detected correctly so I added an option to set Atmega crystal frequency manually. It can be set in the Firmware version menu display. It can be set to Auto, 12, 16, 20, 24 MHz. Default is Auto. When set to Auto it will show detected crystal frequency. If set to any manual frequency it will show star ('*') next to frequency. The value is saved in EEPROM after exiting from the menu.

I had a chance to change my External Sound Card and now it works. I set recommended settings and it works. I set frequency to 20 Mhz.
I don’t know why my previous card didnt’ work.
