Nios boot (Passive serial Configuration)

[osi-hw]

Hi,
I am using a max 10 (CPLD) to configure a cyclone V (passive serial configuration).

The FPGA image is stored in. an external parallel flash connected to the CPLD.

I want to know how to use the memcpy bootcopier in this configuration to store the nios application in external flash and to boot it on the external DDR3.
PS : I was using the onchip-ram to boot nios (execute in place) but now the application is big and I cannot store it on the ocram

Regards.

Hi,

MAX10 only supports internal configuration (from built in FLASH) and JTAG.

See: https://www.intel.com/content/www/us/en/programmable/documentation/sss1393988509894.html

However you can use the PFL IP core in Intel MAX® devices (Intel MAX 10, MAX II, and MAX V devices) or all other FPGAs to program flash memory devices efficiently through the JTAG interface and to control configuration from the flash memory device to the Intel FPGA.

See: https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/ug/ug_pfl.pdf

May check out this handbook https://www.intel.com/content/www/us/en/docs/programmable/683689/current/introduction-28202.html page 332 onwards.

Hi,
Thank you for your reply.
The nios I want to boot is in the cyclone V not mac 10.

the architecture is like this



Parallel Flash -> CPLD -> (passive serial) Cyclone V (with Nios)

To boot the nios in DDR3 using this configuration, the parallel flash should be connected to cyclone V too ? and then follow the steps in the document you sent me ?

Hi,

Click Auto Detect after the programming successful. Click Yes if you are asked to overwrite existing settings. The CFI flash device will be detected and attached to the MAX CPLD.

You may refer to the steps in these documents and designs:

**The boot-copier design in documents use the inbuilt MAX V cpld.
