You can not just write to it. Stack Overflow works best with JavaScript enabled.

Not sure why your stepping into function call would how the wrong parameter. Maximum that you can – read from it as from normal memory only if you have NOR flash. Actually you helped me a lot in making progress – I still have some weird problem left. To copy my data there I just use memcpy. 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.

Yeah youre right, 0x was not the best idea, but according to the datasheet and the AP 0x should be right. Toby 1, 10 36 If I call the function like its designed it doesnt work – if I make a global variable to “pass” the function arguments it works Based on the code you displayed in your question, you are trying to write to external data xdatawhich is RAM, not non-volatile flash datashwet. Okay that link to the application note from silabs helped.

I use the example functions from the AP for the F I don’t know why that is??? Re your question re the MOVX instruction, the app note says: Datawheet datasheet of your microcontroller about their size. Sign up or log in Sign up using Google.

Make sure that memcpy internally use it. To write to flash memory, you need to follow a specific dztasheet to unlock the flash programming circuitry, then erase the area you will be writing to, and then datashet the bytes using MOVX instructions as described in Section 12 of the datasheet. It compiles without problems, but like i already said, it has problems with passing the function parameters You should pick an address toward the top of your flash memory, like 0xF I have can CF Microcontroller from Silabs.

Ddatasheet, erasing done by sectors. But if I leave it disconnected any longer my data gets more or less “resetted” – that means it gets everytime almost the same “reset values”.


Yea according to the datasheet I need to unlock it there is a procedure described there but how do I pick a destination? I mean there can only be one address 0x?!

I wrote a little Interface which stores Information in the non-volatile flash memory from the uC. I mean isnt the flash data non volatile or did I get something wrong? Sign up using Facebook.

Well the copying itself works well Daatsheet looked datsaheet 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.

Down there I tried to implement the example for the F into my code. Now as in the data sheet described I save all the data in between the darasheet 0x – 0x The reason the data disappears after a few seconds, is the power supply capacitor still powers the chip long enough to keep the internal RAM alive.

They called erase sectors. Acording to datasheet of your CPU, to write you have to use special instruction. Only then you can write to it.
