Jumping to ISP from user code

Jumping to ISP from user code

2005-05-04 by ukkie9a

Hello everyone,

I have modified the code in the Philips' application note AN10356 for
the purpose of building a simple solution to in-field firmware
updating (over UART0). The idea is that the bootloader does most of
the work. My updates are at http://compuphase.com/lpc2100_isp.htm.

Kind regards,
Thiadmer Riemersma

Richard,

can you be (a little) more specific with your "NACK"

Once again thanks Thiadmer for a great page.

On a side note, the more recent devices (like the LPC213X) have a new IAP 
command to enter the ISP manually, so this hack is not needed (just call 
the IAP with the command number '57', IIRC).

Hello Richard,

Sorry, I forgot the "www" part. The full link is
http://www.compuphase.com/lpc2100_isp.htm. I often omit the "www" on
web addresses, because most sites work anyway, but I guess that DNS
lookup may take longer.

Kind regards,

Great! I have been developing most software right now on a developer
board with an LPC2106, but the actual device we are designing is based
on the LPC2138. I have thumbed through the LPC2138 manual a few times,
but I did not stumble on this yet. Now I will go look for it.

Thanks,
Thiadmer
