Self-bootable Nios Ssytem (boot copier). How to calculate SOF image size?

Thanks, Nooraini! I'm using Cyclone V 5CSEBA4 , Quartus 18.1 standard licensed.

I find precise dimensions on flash convert generated .map info file.

It reports for uncompressed sof file 0x40_C542

So, I fixed my NIOSII-F offset vector address as 0x50_0000

First, I use first NiosII flash programmer utiliy on SBT ECLIPSE, but I received Error Code 8. (this method runs fine with old attempts with some cyclon based development board..)

Then, I follow strictly official guide "edh_ed_handbook.pdf" and I attempt to obtain a self-booting hardware from EPCQ64A: "on place" and "boot copier" options. These methods uses Quartus Flash convert utility, that allows to compose a JIC file (Flash Programmer, SOf File, Hex File).

Both files (SOF for FPGA) and ELF for nios runs fine loading then with Jtag. (I use an external SDRAM, tested with Nios QSYS system)

Then , I program the chain from QUARTUS FLASH PROGRAMMER on JTAG. It see correctly FPGA+FLASH Chain and program flash correctly.

But It's impossible to obtain a bootable system. FPGA starts correctly (Infact If I load the elf from Eclipse, Nios application runs fine).

Probably I must open a service request about this issue. Only difference from manual is on my external SDRAM instead ON CHIP RAM showed in the example, but addressing mode and qsys settings are the same..... .

This is hard problem for our factory! We havent a bootable system today.... :-(

(ON attach, TEst1 : nios flash programmer->error 8 and TEST2 ->quartus convert test boot copier: it runs but system cannot boot nios)
