You can find the new how to in rockbox's wiki.

This article describes how to run rockbox on vx747 and vx747+.

1. Download rockbox from daily archive or svn. I use the svn version 19703.

2. build the toolchain. You can build the toolchain from ingenic or use the script in rockbox to build the toolchain.

Option 1) download the source code from ingenic ftp and build it.

Option 2) use the rockboxdev.sh in rockbox/tools to build the toolchain.

Add the toolchain to your system's PATH.

3. build the rockbox. If you use the toolchain from ingenic, you should comment the following line in firmware/target/mips/ingenic_jz47xx/boot.lds

#OUTPUT_FORMAT("elf32-littlemips")

If you buile the toolchain from rockboxdev.sh, we do not need to change boot.lds.

cd rockbox-19703

mkdir build

cd build

../tools/configure

Choose 120 for vx747 and 122 for vx747+ and then choose B for buile rockbox for bootloader. It will create Makefile in build directory. Type make to build the rockbox. If everything goes ok, file rockboot.vx747 is created. Rename it to onda.bin.

4. Build and use the usbtool to upload onda.bin to vx747.

cd utils/jz4740_tools/

make

Libusb-dev is needed to build usbtool. You can read the README in jz4740_tools.

Downlaod Log_files.rar and decompress it. Copy 1.bin to utils/jz4740_tools.

./usbtool 10

It will upload onda.bin to your vx747's SDRAM. Do not worry, it won't corrupt your device.

Following is the screenshot of rockbox on vx747.
