Dear my friendsI wanna make pin assignments for flash and Sdram of DE2-70 altera kit but I don't know which one is correct. Could you check it for me (I've attached it in this message)? what is the pin "select_n_to_the_cfi_flash_0"? "tri_state_bridge_0_readn"? "write_n_to_the_cfi_flash_0"? Thank you very much

After compiling and downloading to FPGA, I'd run NIOS II and got this error. How can I fix this error?--- Quote Start --- **** Build of configuration Release for project Homwork **** make -s all includes 1 [main] ?

Which version of Quartus are you using? IIRC this is a common problem with Cygwin. If you search the forum with cygwin, fork and/or "couldn't allocate head" you should have some answers.
