LPC2478 ISP Problem

Development Boards MicroMod

Dear All,

I am currently facing a problem with programming LPC2478 using ISP.

I m getting the following message everything i try to program LPC2478

Operation Failed. Failed to autobaud - step 1.

I have connected serial port to UART0 of LPC2478

The serial cable connections are as follows:

1-1, 2-3, 3-2, 4-6, 5-5, 6-4, 7-8, 8-7… pin 9 is not connected

While programming the LPC2478, I have put the jumpers ISP_E & RST_E whereas RST_SW1 is kept open

In the Flash Magic,

  1. Select Device: LPC2478

COM Port: COM1

Baud Rate: 9600

Interface: None(ISP)

Oscillator(MHz):12

  1. Erase all Flash+Code Rd Plot is ticked

  2. Hex file is selected

  3. Verify after programming

I click on start and then power up the LPC2478 board.

after sometime, the message “Operation Failed. Failed to autobaud - step 1.” is popped up.

Can someone help in solving the problem.

Dear All

The ISP Problem has got solved.

I tried sending 3F to the board using Hercules(hyperterminal) software.

3F was received back on Hercules(hyperterminal). This confirmed me that the board is working properly.

I was powering up the board little late after “Start” button is clicked on Flash Magic. The problem was with resetting the ARM chip.

Thank you.
