If the bootloader does not work for Cyclone IV GX it may be the valdation test fail on the Device ID in the epcs configuration data (in boot_loader_epcs_bits_sii_siii_ciii.S) . You may include the ID for Cyclone IV GX or you may skip the test as it is not nescessary. It is a simple code to understand.
I do not know were to obtain the Device ID, but you may get it from the flash file. This bootloader does however work for Cyclone IV (device ID 0xf7).
