Abstract
Programming or updating hardware electronic circuits without manually accessing the circuits is dislcosed. The circuit arrangement includes an EEPROM device, a FPGA device which is accessible via a computer bus system and a MUX element connected between said devices; a PROM device is arranged, inter alia, for comprising control data for proper recognition of the FPGA by the bus system. The MUX element can be controlled to read data from either the PROM device, EEPROM device, or FPGA device. In the method of the present invention, the FPGA is used to program the EEPROM with the schema received from a disk. The MUX is switched to be able to read from the EEPROM and feed the developed schema therein into the FPGA. The PROM is used to deliver the information to the FPGA, which is necessary for the PC-card to be recognized by the BIOS on a first start-up.
