UBooting with dual compressed images on a MAX 10

Hi,

 

For reliability, we want to have dual compressed hardware design images stored in the CFM of a MAX10 device.  Is it possible to have each hardware image boot a different software image from UFM?  If not, what's the point of having two hardware images?

The point of dual image is to have safe fallback with remote system upgrade. RSU IP has no specific prerequisites for switching UFM data, but you can implement it in FPGA code if memory capacity sufficient, I guess.

Hi,

Greetings and welcome to Intel's Forum.

Unfortunately, the UFM data (.HEX file) can be included in either Page_0 or Page_1 only. The On-chip flash does not support two .HEX files for Dual Compressed images configuration mode.


Here are additional information on the Max10 On Chip Flash for your reference:https://www.intel.com/content/www/us/en/docs/programmable/683689/current/fpga-on-chip-flash-description.html


Hope this clarify your doubts.


Thank you.

Thanks for the replies.

 

Actually I have discovered that it can be done.  For the first image set, you must create a hardware image with Nios 2 vectors set to the base address of UFM.  Generate the BSP based on that Qsys design, and compile the software.  For the second image set, give the Nios 2 vectors an offset of 0x8000, for example, which will push the second software image to Page_1 of UFM.  After generating this BSP and compiling the second software image, concatenate all but the last line of the first .hex file into a new .hex file, then append the second software image's .hex file onto that to create a single, combined .hex file.  Convert the combined  .hex file, and the two .sof files as usual.

 

After 4 months of working on this problem I discovered the trick of removing the last line of the first software image's .hex file only this morning. 

 

Thank You,
