Toby 1, 10 36 Not sure why your stepping into function call would how the wrong parameter.

I use the example functions from the AP for the F Maximum that you can – read from it as from normal memory only if you have NOR flash. Down there I tried to implement the example for the F into my code. You can not just write to it. Re your question re the MOVX instruction, the app note says: Based on the code you displayed in your question, you are trying to write to external data xdatawhich is RAM, not non-volatile flash memory.

Yeah youre right, 0x was not the best idea, but according to the datasheet and the AP 0x should be right.

To write to flash memory, you need to follow a specific protocol to unlock the flash programming circuitry, then erase the area you will be writing to, and then write the bytes using MOVX instructions as described in Section 12 of dataeheet datasheet.

They called erase sectors. By using our site, you acknowledge darasheet you have read and understand our Dtaasheet PolicyPrivacy Policyand our Terms of Service. I wrote a little Interface which stores Information in the non-volatile flash memory from the uC.

If I call the function like its designed it doesnt work – if I make a global variable to “pass” the function arguments it works Email Required, but never shown. I mean there can only be one address 0x?! Is there any way?

Actually you helped me a lot in making progress – I still have some weird problem left. You should pick an address toward the top of your flash memory, like 0xF I don’t know why that is??? It compiles without problems, but like i already said, it has problems with passing the function parameters But if Dataheet leave it disconnected any longer my data gets more or less “resetted” – that means it gets everytime almost the same “reset values”.

I mean isnt the flash data non volatile or did Datashet get something wrong? However I question your use of 0x for a Flash address to use for data, that would normally be right in the middle of where your code is placed, unless you have modified your linker script. Well the copying itself works well I looked up at the flash memory and it saved my data right – If I now disconnect my uC and connect it again in like 5 secs, the data is still there.

Now as in the data sheet described I save all the data in between the addresses 0x – 0x Normaly, erasing done by sectors. Make sure that memcpy internally use it. See datasheet of your microcontroller about their size.
