What is pm_uc_ww49p5_main.hex?

Question

After changing the Memory Editor to read byte-addresses instead of word-addresses I am getting the warningWarning (113006): Word addressed memory initialization file "pm_uc_ww49p5_main.hex" was read in the byte-addressed formatI get that warning twice in a row.  I don't have any idea where that file belongs.  It is not in my project, but is at:  C:\intelFPGA\17.1\quartus\common\devinfo\20nm
ightfury3I am wondering if it is the lowest level loader for the ARM core. Anyone have any clues?

Hello,
Are you trying to read the memory content of on chip memory on FPGA in Quartus?
Or is it the memory editor in Eclipse?
The on chip memory is initialized with a default hex file, unless the developer would use a specified hex instead of the default one, or disable the default initialization file.

Hello,I am not trying to read the content of the on-chip memory--only trying to understand the boot process at the lowest level.  If it is possible to edit or modify the pre-loader, that would be interesting to me--even if we most likely would not do that.Thanks,Brian
