You may download it using link below (choose Quartus version 15.0.0):
Uncompressed the max10_RSU.par (using Quartus) --> the "max10_RSU_project" folder will created --> Open "max10_RSU_project" folder and open "Terminal" folder.
- I have downloaded it, but according to "AN 741: Remote System Upgrade for MAX 10 FPGA Devices over UART with the Nios II Processor", it shows that key-in 1 in the Send text box and then hit Enter. A list of operation choice will appear on the terminal, I did not see it. The problem is the version of the software (I use 19.0 limit )? Or other settings I did not put?
