OK, I found an image file in the SDK directory.
Can I burn this image file into an EEPROM using external programmer and then install it onto my board? My EEPROM is 24LC256 (32kbytes) but this image file has a length of 128kbytes. Should I replace my EEPROM with 24C1024 (for example, AT24C1024) ?
I navigator this forum and found some useful topics.
1) If I boot my usb board from host, I have to install an external 32K crystal;
2) If I boot the usb board from host, my board may or may not work correctly. If my board can not work correctly because of silicon problem, replug my board may be a good choice;
3) If I boot from I2C and use the lastest SDK, the external 32K crystal can be omitted;
Are these descriptions right?
Main question is what "sometimes" means :
1) does it mean that on certain type of PC USB controller, it will never wok and on on another type it will always work ?
2) or does it mean that on whatever PC USB controller, it will "sometimes" fail and at what typical frequency : for example, 1 every 10 boots, 1 every 100 boots, etc ?
3) does it depends on board environment, etc ?
