I use all type of loading option for development board lpc2148. I check my Cable and usb CP2102 is working well I check it by command running ON my GSM Modem. I use XP RS232 com 1 port, windows 7 usb type a to usb type b and then CP210x convertor, and on windows 8.1 directly use USB to Serial cp210x convertor. but in all stage error is Auto baud error step-1. and some times it shows cannot read device signature.
Please any one can help me to solve this problem....
