A notes for developers (might be outdated):

Requirements:

  • git, python
  • STLinux 2.4 (all-sh4-glibc) - http://www.stlinux.com - installed to /opt/STM/STLinux-2.4/
  • fakeroot package/tools

Compilation:

  • just type 'make'
  • kernel with rootfs is in kernel/arch/sh/boot/uImage.gz

Booting uImage.gz on Inverto IDL-400S/Grundig GSS.BOX/Telestar Digibit R1 from USB:

  • connect TTL USB serial adapter to J3 connector (4 pins at the power supply)
    • pin 1 = 3.6V (do not use), pin 2 = GND, pin 3 = RXD (STM CPU), pin 4 = TXD (STM CPU)
    • parameters: 115200,8N1
  • press 'Enter' when you turn on the box (you have only one second) to get 'idl4k> ' prompt (it seems that 'Enter' is required also to enable the serial console)
  • modify bootargs (optional - for original firmware)

set bootargs=console=ttyAS0,115200

  • set debugfw environment variable

set debugfw "debugfw=usb start;usb start;fatload usb 0 0x84000000 uimage.gz;set bootargs console=ttyAS0,115200 bigphysarea=20000;bootm 0x84000000"

  • you may type 'save' to store this settings permanently
  • to execute the debugfw type 'run debugfw'
  • note that the USB stick should be in the first (upper) USB connector

Configuration

  • dhcp client, telnetd, dropbear (ssh daemon) and minisatip are active by default
  • configuration is stored in /etc/sysconfig/config
