Hi Jake, could you please share your modified boot loader? I change the boot_loader_epcs_bits_sii_siii_ciii.S under C:\altera\81\nios2eds\components\altera_nios2\boot_loader_sources, make the boot loader, convert boot_loader_epcs_bits_sii_siii_ciii.elf to hex and then update the SOF but my application image never booted.

I used Cyclone III, EPCS16, factory sof + sw image is at offset 0 of the EPCS while the application sof and its sw image is at offset 0x100000 of the EPCS.

I change line 99 of the assemble code from

movi r_flash_ptr, 0

to

movi r_flash_ptr, 0x100000

TIA
