Hello

I assume you are using a HCS12 CPU. Am I right?

Which derivative are you using (HCS12DP256, ...)?

Hello CrasyCat

Yes, i am using the E64, with a web page, but the page is allocated in memory of program. This is very great to allocated in RAM.

I need update some bytes and so send the web page with new datas.

The version of CW is 3.1 in c but if the solution is in assembler, don't care.

Jacobo.

What I believe you are looking for is to alter non-volatile memory cells, either the eeprom or the flash. There is an app note describing how to do this on the S12 homepage. Also search these boards for "flash programming", "NVM programming" etc, for hints and common mistakes.

Hello,

Please do use subjects matching the requirement described in the following.

• [IMPORTANT] When Asking about CODEWARRIOR !!!

Your message will then probably be moved to the proper core board, if available.

Many thanks on behalf of all readers.
