RSU Module Compatibility with MAX 10 Devices

[mkmk1]

Hi,

I'm planning to use the RSU module, adapting it slightly by replacing the I²C interface and tailoring it to my needs.

https://www.intel.com/content/www/us/en/design-example/714746/intel-max-10-fpga-i2c-remote-system-update-design-example.html

However, I encountered a significant issue in the current implementation.
In the slave-side top-level file FLASH_LOADER.v, there's an instantiation of MAX10_REMOTE_UPDATE.v, which in turn instantiates the following module:

fiftyfivenm_rublock RuBlock (

  .clk        (Clock),

  .shiftnld   (RuShiftNLd),

  .captnupdt  (RuCaptNUpdt),

  .regin      (RuDin[0]),

  .rsttimer   (WatchdogKick[4]),

  .rconfig    (RuConfig),

  .regout     (RuDout)

);

The problem is that fiftyfivenm_rublock is not supported by the MAX 10 device family.
This raises a few questions:

• Do you know of any implementation of this RSU module that works on MAX 10 devices?
• If so, how was this achieved despite the apparent incompatibility?
• Since this RSU module seems intended for MAX 10 devices, am I missing something?

I’d appreciate any clarification you can provide.

Thanks,
Mkmk

Hello,

MAX10 dont support fiftyfivenm_rublock module. Only supported by Stratix V or Cyclone V series.

You may refer to below working design example build specifically for MAX10:

• RSU over UART using Nios II 2
• I2C-based RSU example1

The design used : On-chip flash IP, Dual Configuration IP, NIOS II processor etc.

On MAX10, RSU is managed via On-chip flash IP, which allows writing to the CFM sectors.

Please refer to AN741 for more details.

regards,

Farabi
