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
Try a different USB-to-serial adapter, or check if it makes a difference to try another baudrate.
Note that a USB-to-serial adapter does not give you a perfect emulation of a serial port. They have issues - one of them being lag between the USB interface and actual toggling of the RS-232 pins. Some programs and some protocols are less affected by this - some are more affected. And depending on the adapter is implemented, some programs will just not able to use it for some tasks.
