EPCS embedded reprogramming

Hi, I'm trying to figure out how to reprogram the epcs from within the uClinux environment on the NIOS. Has anyone tried this. Is it possible to use the MTD drivers for the EPCS to reprogram...

ok, i tried to take an srec and convert it to a binary to use for dd, but the objcopy in linux couldn't recognize the nios srec. is there another way to convert it into something that can be copied using dd?

You should look at the .flash format of altera.

And write a utility to convert .flash to binary. 

# Creating .flash file for the FPGA configuration
sof2flash --epcs --input=$SOPC_KIT_NIOS2/examples/verilog/niosII_cycloneII_2c35/standard/standard.sof --output=standard.flash#  Creating .flash file for the project
elf2flash --epcs --after=standard.flash --input=zImage --output=epcs_controller.flash --boot=$SOPC_KIT_NIOS2/components/altera_nios2/boot_loader_epcs.srec
