Cyclone 10LP Evaluation Kit - Execute in Place (XIP) from EPCQ Flash

Hello,

I am working with the Cyclone 10LP Evaluation Kit Booting options and had success testing the boot copier from EPCQ flash (using EPCQ64).

I am now trying to get the XIP Boot mode working and not having success.

Are there any instructions that are not included in AN 736?

I followed AN 736, table 3: BSP Editor Mappings and Figure 5: Exception Vector set to OCRAM. The other steps taken are the same as in the app note.

Thanks in advance

      I believe they are setup correctly, I have outlined the steps taken so far

      1) Platform Designer

      • Reset Vector Memory: EPCQ64.avl_mem
      • Reset Vector offset: 0x0008_0000
      • Reset Vector: 0x0088_0000
      • OCRAM Memory Size: 40,500 bytes
      • S1 Data Width: 32

      2) Launch Eclipse, BSP Editor

      • Settings -> Advanced -> hal -> Linker
        • ALL CHECKED (My Exception vector is set to OCRAM)
      • Linker Section Names all set to OCRAM, except .text and .entry (EPCQ64_avl_mem)
      • Click generate

      3) Build Project

      • Build project to generate .elf
      • Run Make Target -> Build -> mem_init

      4) Convert Programming File

      • Flash Loader added
      • SOF file loaded (compressed checked)
      • Hex Data loaded (Absolute addressing) --> starts at 0x0008_0000

      ***Convert Program File Error : Size of file(s) in EPCQ64 exceeds memory capacity***

      After this point it is saying my EPCQ64.hex is bigger than the memory capacity.

      I did notice my hex files were empty (EPCQ64 and OCRAM). I cleaned the project and rebuilt the mem_init scripts. but no luck

      Sounds good, will try that.

      Do the steps I outlined from above look right?
