Hello. I study ARM in Altera Cyclone V SoC. I use Eclipse for DS-5. But I don't to start example. Somebody programmed ARM for Cyclone V SoC in Eclipse DS-5?
You should also check out Code Time Technologies
They have a multicore RTOS that lets you take advantage of the dual ARM cores on the Arria (or Cyclone), as well as their own peripheral drivers for EMAC, SDMMC, etc. that are integrated with open-source stacks (ie. lwIP, FatFS). The RTOS start-up also takes care of the tricky parts related to configuring the cache and snoop controllers, MMU, etc.
Basically, you can get all the stuff that Altera doesn't provide.
