ABOUT miZy_spi_image_builder

SPI-flash miZy firmware image builder (for sunxi Orange Pi Zero, another sunxi boards maybe work too ) also Hybrid-image generate for SD card (spi emulate on sd card)

Its just a part or miZy project, and same as other our parts can standalone used

This perl script no need any libs or another deps

Get Source

mkdir /tmp/zero_builder
cd /tmp/zero_builder
git clone https://github.com/hyphop/miZy-spi-image-builder.git
cd miZy-spi-image-builder

USAGE

help

./miZy_spi_image_builder --help

common usage for 8M image, output to firmwares/orange_pi_zero_hyphop_mizy_spi_flash_demo-8M.bin

./miZy_spi_image_builder

custom config

./miZy_spi_image_builder miZy-spi_image_builder_custom.conf

set 16M image size

img_size=16M ./miZy_spi_image_builder

not padded by flash size, save only used space

img_size=0 ./miZy_spi_image_builder

override image out name

img_name=out/my_image_name%s.bin ./miZy_spi_image_builder

check build status in shell

./miZy_spi_image_builder && echo "build ok"
./miZy_spi_image_builder || echo "build fail"

BUILD EXAMPLES

https://github.com/hyphop/miZy-spi-image-builder/tree/master/examples

write image to SPI from host to working device

easy way for upgrade / rewrite system

scp firmwares/*.bin root@zeru:/tmp
dd bs=65536 of=/dev/mtdblock5 < /tmp/*.bin

163+1 records in
163+1 records out
10743872 bytes (10.2MB) copied, 61.941887 seconds, 169.4KB/s

Hybrid image

by default miZy_spi_image_builder generate hybrid image its simple raw image, which can used for SPI and same for SD/MMC. this image equal spi-flash rom and ready for direct write to SPI flash, but we can write this image to SD/MMC for test work on device, and next copy this image to SPI from booted SD/MMC,

write hybrid image to SD/MMC

dd seek=16 bs=512 of=/dev/mmcblk0 < firmwares/mizy_spi_flash_demo-8M.bin

write hybrid image direct to SPI ( /dev/mtdblock5 - full size spi-flash mtd block dev)

dd bs=65536 of=/dev/mtdblock5 < /tmp/mizy_spi_flash_demo-8M.bin

write hybrid image direct to SPI via mtd

mtd write /tmp/mizy_spi_flash_demo-8M.bin full

write hybrid image to SPI via sunxi-tooll FEL mode from host machine

sunxi-fel -p spiflash-write 0 firmwares/mizy_spi_flash_demo-8M.bin

generate MMC image

output raw mmc image (this image usable for mmc, not for SPI )

MMC=1 img_name=firmwares/mizy_mmc_image.bin ./miZy_spi_image_builder 

add one partiotion and write some readme info there

./miZy_mmc_add_partitions firmwares/mizy_mmc_image.bin 8x8

write mmc image to SD/MMC

dd of=/dev/mmcblk0 < firmwares/mizy_mmc_image.bin

copy from booted MMC image to SPI, directly from working device

mmc_copy_to_spi
mmc_copy_to_spi yes

ok system is ready for full loading from spi now u can remove sd card, and reboot system from spi already!

CONFIG FILE

default config

miZy-spi_image_builder.conf

config file its a same pure perl code!

PATHS

put your files (uboot scripts env fex/dtc kernel squashfs initramfs userdata) in @SCAN_PATH dirs by default are

.
./bin
./bin.local

TOOLS

miZy

tiny fast embedded linux, for sunxi Orange Pi Zero (and maybe other boards) and mods. Now under active development, but is usable already )

write image to device in FEL mode

in FEL mode via sunxi-fel tools

check spi flash size

./tools/fel_spi_info
Manufacturer: Winbond (EFh), model: 40h, size: 16777216 bytes.

ok! write image - u can write any image size <= flash size

./tools/fel_spi_write firmwares/orange_pi_zero_hyphop_mizy_spi_flash_demo-8M.bin
