Re: Flash Magic / LPC1114 with internal OSC

Started by "sre...@gmail.com [lpc2000]" October 18, 2014
I am new in 32 bit micro controllers. Now I am using LPC11A12FBD48 in my project. I planing to use FLASH MAGIC for burning my hex file. I don't have a development board with me. So I planed to design a new PCB. Now I am so confusing with the TXD and RXD pin for burning purpose. In its user manual ti is saying like there are 4 TXD and 4 RXD pin. For burning my program which pin should i use? or what will be the default pin for UART boot loader? I have searched a lot in NXP site. Please help me.

Hi,

I'm not familiar with LPC11A12 but you can check and study schematic
drawings from known development boards (Keil, Olimex and most development
board manufacturers have their shcematics available on their websites).
Usualy the uC manual has a section devoted to serial programming it should
state the pins.

Port pin PIO_12(RXD) and PIO_13(TXD) to be used while programing. Please
refer page no 16 of data sheet. At both port pin its mentioned "This pin is
used for ISP (in system programming) communication.
