 		 #108262 - The HW is prepared
Responding to: ???'s previous message
The external code execution already works and I program this external flash from the microcontroller dividing my big program into pieces. I can also program In-System the micro using the FLIP PC program of ATMEL.

The micro´s internal flash is programmed by the bootloader using the flash API-s implemented through this bootloader, and when program is running in the micro, its code flash also can be programmed using these API-s.

The source-code of the bootloader for the T89C51CC01 is available in the ATMEL website.

What I really want is to carry out the programming of both the micro and the external flash in one step using a program like the FLIP. That´s why I say the default bootloader provided by ATMEL should be modified to program also the external flash.

Somebody knows if this is already done ?

Thanks to everybody !!
