Hello I am trying to run Baremetal appication on Cyclone V SoC on SoCrates 1.2 board.
Simple applications like Altera-SoCFPGA-HelloWorld-Baremetal works, but as I get to Altera-SocFPGA-HardwareLib-FPGA example it just hangs on waiting for spl_boot_device breakpoint, then I have to push reset button to make it do anything.
I have tried also replacing u-boot with u-boot that ist working for linux on the same board with no results. I've tried both ARMCC and GCC compilers.
I've tried to work from HelloWorld example but there are two limitations, applications can by only 64K and there is no access to memory out of 0xFFFF0000 to 0xFFFFFFF region and memory mapped devices in FPGA on AXI bus.
There is log from Commands window of DS-5:
Is there anyway to fix hangs when using u-boot and baremetal or to not use u-boot at all and get access to memory mapped devices?
Thank you.
