Hello Matthias, thank you for the answer, but everything you have written was clear before - sorry.
I have quoted the relevant part before: --------------------------- zip -------------------------- http://amforth.sourceforge.net/TG/Hardware.html#fuses Fuses are the main cause for problems with the flash write operations. If the !i operation fails, make sure that the code for it is within the boot loader section. It is recommended to make the bootloader section as large as the NRWW section, otherwise the basic machine instruction spm may fail silently and the controller becomes unresponsive. --------------------------- zap -------------------------- The main question is how the restrictions are regarding the bootloader? You did not answer to this problem which is the part i really did not understand. At this time i have hfuse = 80 lfuse = AF with a 16 MHz crystal and low level Brownout detection. I am using simply such a test board: http://www.ebay.com/itm/261121351546 Cheers Karsten > Sorry if this is not the answer you may have expected. I think you have not understand my problem with the documentation. ------------------------------------------------------------------------------ Comprehensive Server Monitoring with Site24x7.
