Failed to read device signature (operation failed, reading signature)

evoluer — Tue, 12 Sep 2017 08:28:52 GMT

Hello all,

I am having a problem for the last 3 weeks and i am not able to find a solution for it. Let me explain the problem in detail.

When i try to download the program, i get the following error Failed to read device signature ( operation failed .(reading signature)). Accessing a device using the wrong protocol could render the device unusable. Do you want to continue?

controller: lpc2148

oscillator: 12MHz crystal

serial connection through max3232

reset and program switch connection

Software used : Flashmagic version9.73.4146 arm7 UART driver version: 5.00.3965

Hope someone can point me in the right direction
