Could it be that the firmware download only works after a cold boot? A firmware download is not necessary after sleep. In this case, i have an explaination: It is possible to remap the eeprom to another address to allow firmware updates. If it is remapped, the dsp will not find it and... The eeprom address normally is controlled with a GPIO pin of the channel decoder. At first start, the pin is tristate and download works due to a resistor. Its the same with a card i am working on here. So i can provide you a patch the next days. Best regards Hartmut
