LPC4337 - UART0 boot image help

Hello,

I have worked with lower powered ARM processors before although using a boot image from UART is new to me.  So I'm curious, can anybody give an example of the setup that will allow the LPC4337 to boot off of UARt0?
I'm using this development board from china

Would I have to use some sort of AVR microcontroller to communicate over UART.

What gets me is the header or any special dependencies that I can't really store in code of a slave microcontroller.  Where would I store the image if I'm not using SPIFL?

No, you don't need an AVR.

You need a USB-serial converter with 3.3V logic levels (I got some called FTDI Breakout).

You need to figure out the RXD and TXD pins for the serial port used by ISP from the user manual. Connect RXD of the controller to TXD of the FTDI breakout and vice versa.

Connect DTR to reset or reset the controller manually.

If available connect RTS to the pin used for entering the boot loader (look into the user manual). Otherwise set it to low manually to enter the boot loader, and high to enter your firmware.

It goes without saying that you need to connect ground.

As software for flashing use FlashMagic (MS Window) or lpc21isp (Linux).

So far the instructions is generic for LPC controllers.

On the LPC43xx you may need to check if you have to set the boot jumpers in a specific way (I'm not sure, it's been a long time since I did this.)
