I am thinking H/W is well, because I am programming using UART (ISP via UART)only....

Have you configured the UART pins in IOCONFIG?

what about the SYSAHBCLKCTRL register?

are they configured properly?

Hi,

the following is the part of my code configuring UART pins & enabling CLK for UART

                LPC_IOCON->PIO1_6 &= ~0x07;    /*  UART I/O config */
                LPC_IOCON->PIO1_6 |= 0x01;     /* UART RXD */
                LPC_IOCON->PIO1_7 &= ~0x07;
                LPC_IOCON->PIO1_7 |= 0x01;     /* UART TXD */

                LPC_SYSCON->SYSAHBCLKCTRL |= (1<<12);  // UART CLK
