I studied using the SOPC builder and NIOS2. I made the projects in both tutorials provided by altera. Along the way, I encountered errors but I searched about them and found solutions. I made the tutorials worked on my board so I decided to try on the tutorial on sd card interface using SOPC builder. At the end part, for the software, I used the HAL device driver but when I compiled it, there were errors.



the last lines in my console are as follows:


Do you have any idea on how to solve this? I already tried running my nios 2 eds as an administrator (from another forum’s answer) but it didn’t help me.
THANKS IN ADVANCE!

hi. thanks for the reply.

my onchip-memory is 32kb. could you identify the problem here? does this have something to do with the address? im not really familiar with this since im a beginner but i really need to finish this. thanks again.

thank you for replying. i found a way to make it work though. i remade it in nios2 and this time, i used the hello world small template. it worked! i was able to write a txt file in my sd card now! thanks again for the reply. i don't know what are the differences between these templates though, i just got this suggestion from other threads.

my next problem would be reading a bitmap image from sd card and store it to sdram. it seems this is c programming and a problem for me coz i only know basic c. can you give me references on this?
