Hi all.,
From the PC COM port., I am able to Load the hex file into My LPC2148 board using flash magic. But, When I try do it with laptop by using USB-Serial Converter cable. It is giving error message like step1 is having some problem. That USB to Serial Converter is working fine., I checked it GSM Modem by sending commands and it able to receive acknowledgement by using same USB to Serial converter.
For load my hex file from laptop using Using USB to Serial converter., What should I do?
Please tell me., If any one know the solution to this particular problem.
Thank you all in advance Ganesh kaila
Maybe just show all serial ports (even non-connected) in the device manager and then uninstall them all and then insert your USB adapter. This time, it should get a lower serial port name.
By the way - only buy USB-to-serial adapters that have an EEPROM with a serial number. With a serial number, you can move the adapter between different USB ports and it will still keep the name. An adapter without a serial number will get a new name for every USB port it is inserted in. Without a serial number, Windows have to include the USB port name into the name of the full device to be able to correctly point out the serial port.
