Eddy DK Programmer Guide

Chapter 5. Creating Firmware

On the previous chapter, we explained how to make and compile application program with sample program. This

chapter introduces methods to create a firmware which permanently saves the application into the Eddy module and

apply it to hardware of Eddy.

5.1 How to Create a Firmware

Firmware image can be created on filesystem_2.x.x.x/ramdisk folder.

Modify ‚Makefile‛ on filesystem_2.x.x.x/ramdisk folder to create a firmware image.

Version info, required Ramdisk amount and desired application to copy can be set up on the ‚Makefile‛.

(NOTE)

Provided DK Sources are Linux based. Some commands are not executable on Windows

environment. To prevent this problem, a suffix, ‚exe‛, has to be added for some utilities after

file name as shown below.

../tool/genext2fs  ../tool/genext2fs.exe

../tool/mkimage  ../tool/mkimage.exe

IMAGE=ramdisk

FW_NAME = eddy-fs-2.x.x.x.bin  Name and Version Info of Firmware Image

FIRMWARE_DIR = ../firmware  Folder to store created firmware

install:

#@echo "Making ramdisk image..."

#$(TOOL) -b 8192 -d root -D device_table.txt ramdisk

#../tool/genext2fs -U -b 5110 -d root -D device_table.txt ramdisk

#../tool/genext2fs -U -b 7158 -d root -D device_table.txt ramdisk

#../tool/mkcramfs -q -D device_table.txt root ramdisk

./tool/genext2fs.exe -U -b 10240 -N 1024 -d root -D device_table.txt ramdisk  Make size of

Ramdisk to 10,240 K and register the device of Eddy/dev as indicated on Devide_table.txt.

gzip -vf9 ramdisk

est -f ramdisk.gz

./tool/mkimage.exe -A arm -O linux -T ramdisk -C gzip -a 0 -e 0 -n $(FW_NAME) -d ./ramdisk.gz

$(FW_NAME)

test -f $(FW_NAME)

mv $(FW_NAME) $(FIRMWARE_DIR)/

release:  Register the desired application to the folder for copying to Eddy

cp -f ../src/Eddy_APPs/hello_world root/sbin

cp -f ../src/Eddy_APPs/eddy root/sbin
