Make sure that memcpy internally use it. Maximum that you can – read from it as from normal memory only if you have NOR flash. Sign up using Facebook. Is there any way? I wrote a little Interface which stores Information in the non-volatile flash memory from the uC. datsaheet

Actually you helped me a x8051f340 in making progress – I still have some weird problem left. 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. To copy my data there I just use memcpy. I don’t know why that is??? See datasheet of your microcontroller about their size.
You should pick an address toward the top of your flash memory, like 0xF 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 the datasheet.

They called erase sectors.

But if I leave it disconnected any longer my data gets more or less “resetted” – that means it gets everytime almost datsheet same “reset values”. Normaly, datsheet done by sectors. If I call the function like its designed it doesnt work – if I make a global variable to “pass” the function arguments it works Re your question re the MOVX instruction, the app note says: But if you want to write to it, you have to the first of all erase it set all bits to 1.
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. I mean there can only be one address 0x?!
c – Flash Memory in F Microcontroller gets erased – Stack Overflow
I have can CF Microcontroller from Silabs. Email Required, but never shown. I use the example functions from the AP for the F It compiles without problems, but like i already said, it has problems with passing the function parameters Not sure why your stepping into function call would how the wrong parameter. Yea according to the datasheet Ddatasheet need to unlock it there is a procedure described there but how do I pick a destination?
Only then you can write to it.
