Error during loading new program for NIOS 2 - Error during loading new program for NIOS 2 Hi, get now an error in a project which worked before. No updates of tools!! Where to look around? With best regards Gerhard Replies: Re: Error during loading new program for NIOS 2 Sorry, solved. Oh my god. After altering the NIOSII by adding a PIO the symbol for the block symbol file was altered too, and gets two grid ticks broader. This breaks the connection to the pin defines for the SDTam clock signal. No error during compilation, maybe a warning? Without clock, the SDRam do not work properly and so the download fails.... Sorry about this message. With best regards Gerhard
