Hi,

I am developing a prototype using LPC4330FBD144.
I am newbie to LPC4330 but I already worked with LPC1788.
I am using M25P40 SPI flash device to store the bootloader program for LPC4330.

1. I want to know what are the ways in which I can download the bootloader into external SPI flash device.
2. I also want to know if there is any way to download the bootloader using ISP into external SPI flash device.

Please do help me in this regard.

Thank You in Advance

you can do this with flash magic, you may need to provide the programmer code for it to download, but there are examples included with it for the Hitex board which might work, or at least be a good starting point.

For my device PM25LV010 I modified programming algorithm for DFUsec utility.
Note, that chip on HItex board and M25P40 are using different command set and connection to LPC4300.
For booting from M25P40 you can use SPI(SSP) interface.
