New ContributorHi Anand,
Thank you for the reply.
Your understanding is basically right. I am using MAX 10 device, and building a qsys with 2-Nios II processor and boot from on-chip flash. But I don't think I am using Dual Compressed Images configuration mode. I think Dual Boot is for the case when you want to fpga to switch between two designs. For my case I just have one design with two processors running at the same time.
In this document<Creating Multiprocessor Nios II Systems> https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/tt/tt_nios2_multiprocessor_tutorial.pdf, it mentions that "The Nios II Flash Programmer is able to program bootable code for multiple processors into a single flash device.". But It does not mention how can I do it, how can I put multiple program codes into one flash device. That's the part that I want to know.
In other word, after build the two software programs for each of the two processors, I got two .elf files(and also two .hex files after make mem_init_generate), how can I merge the files together into one file and then program the flash.
In qsys, I can only specify one .hex file for flash initialization.
Regular ContributorHi yying5,
Thanks for clarifying.
User Flash Memory (UFM)—to store user data or software applications. Max 10 device supports only one .hex file.
But if you use external flash like qspi you can do it.
Please refer below link for booting methods and steps.

Let me know if you need any further assistance.
