It seems to me I've fixed this issue :)
The pitfall is linker script: *.ld. The default linker script by Altera from Quartus directory assumed there are 1024 Mb of memory installed on the board. But there are only 512 in our custom board so debugger probably doesn't allow to start application which was linked for 1Gb SDRAM. I've customized linker script for myself:
MEMORY
{
boot_rom (rx) : ORIGIN = 0xfffd0000, LENGTH = 64K
oc_ram (rwx) : ORIGIN = 0xffff0000, LENGTH = 64K
/* Need to have 64bytes available before start of program, to store the mkimage header */
ram (rwx) : ORIGIN = 0x100000 + 0x40, LENGTH = 511M - 0x40
}
and it starts work! The real problem is that it's not obvious at all. Maybe for ARM guru, but not for RTL designer! The lack of programming documentation gathered in UG is the major issue I think...

Hi, I am working on the same issue as well, but wasn't able to find documentation to explain the memory parameter. The example provided by Altera was a simple Hello World program that I managed to get it to work, but once I included the GPIO and QSPI features into the program, the UART console does not print out message. I realize the binary output file is larger because of added in features, so does the mkimage header require a larger available memory before start of program? I just wonder if you know anything that can help resolve my issue?
