I'll just read the posts. Previously I've still a question of principle.

I have no EPCS device on my FPGA-development board.

- For downloading the FPGA-Firmware from flash to the fpga, i use a CPLD device

- to download the nios-firmware from flash to NIOSII-processor i'll use the bootloader

- the bootloader have to copy the nios-firmware data to the SDRAM

-finally when i reset my fpga-firmware, the current firmware should automatically run as well as I would load the firmware via jtag

Does the bootloader works on this conditions ?

Thank you
