|
||
|
|
-------------------------------------------
|
||
|
|
|
||
|
|
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
|
||
|
|
|
||
|
