Andy,

Have you got any suggestions on using FM to interact with custom bootloader code? For example, is it feasible to have FM execute the GO command to run my bootloader and then continue to push a hex file down to my bootloader? Or am I doomed to have to write both sides of the file transfer?

Thanks for your help,
Steve

Hi,

I'm trying to figure out how to use FM to load a 1 MByte FPGA config file. I'm using an LPC2378 that needs to load a serial flash over the SPI bus. The problem is that the file is too large to simply store in on-board flash and transfer to serial flash later. Do I need to write my own bootloader code to interact with FM?
All suggestions welcome.

Thanks,
Steve

Paul,

So FM recombines the two "ASCII" data bytes in the hex file back into one binary byte and then uuencodes it. I was thinking FM uuencoded each ASCII byte in the hex file which would be really inefficient. This makes more sense.

Thanks,
Steve

Paul,

Thanks for the reply. Just seems strange that NXP wants the data uuencoded when Intel hex is already "ascii-ized".

Hi,

I have a general question about the file format used as input by FlashMagic.
The user's manual says the input file should be uuencoded, but FM says to
specify an Intel Hex file. What am I missing?

Thanks,
Steve
