Honored ContributorHi Alex,
Thanks your information. I had read above documents before. I saw the flash is separated into two parts UFM and CFM. The UFM is for user data and NIOSII program (.hex) files. The CFM is for hard code (.sof) files. Therefore, i'm not very understand how to distinguish where space is stored user data and where is stored (.hex) file?? At first, i want to use single uncompressed image mode because the CFM2 can virtual to the UFM. That sector i can use it to put my user data. However, i choose it but the error happened. So, i only choose single uncompressed image with initialization (chip type: 10M08DAFC8GES). The follow is my way: Step 1 : Set configuration mode into single uncompressed image with initialization and modify the CFM2, CFM1, CFM0 from hidden into read & write in qsys . https://www.alteraforum.com/forum/attachment.php?attachmentid=11474 Step 2 : Of course the configuration mode need to changed in Quartusii. Step 3 : I use CFM2 region to stored my user data. I guess the (.sof) is stored in CFM0 and CFM1. So i decided to use CFM2 to store my user data. Although it can work now. But i don't know this method is correct or not.
