I transfer the bin file to my device through ADS over EtherCAT protocol. I have checked at the receiving end if there is any dataloss but the data is intact. And then I use the alt_write_flash function to write the whole data in to my flash device with offset as '0' and length equal to the my file size.

Please find below the commands that I use to convert my flash files to a bin file. Are they alright??

sof2flash --input=widrive.sof --output=widrivehardware.flash --epcs --verbose

elf2flash --input=drive_fpga.elf --output=widrivesoftware.flash --epcs --after=widrivehardware.flash --verbose

nios2-elf-objcopy -i srec -o binary widrivesoftware.flash softwarefirmware.bin"

nios2-elf-objcopy -i srec -o binary widrivehardware.flash hardwarefirmware.bin"

cat softwarefirmware.bin hardwarefirmware.bin > firmware.bin
