does anybody have a good online refrence with information on writing a boot loader for 8051 MCU's to write to external flash memory?
The december 1999 issue of Embedded Systems magazine had an article about 8051 flash based systems. The article is available from the web site http://www.embedded.com.
Hi Check the link http://www.eu.renesas.com/documents/mpumcu/ app_notes/app13010.pdf This is an application note for H8S Serial Bootloader With Xmodem Data Transfer. I guess this can be ported to 8051. Best regards SenthilKumar.S Chennai
why not just use a derivative such as the P89C51Rx2/P89C66x with built in bootloaders Erik
