I'm trying to understand the mechanisms of the Android bootloader. The source code for this is here:

I want to see the messages which are printed by LOGE(stdout, "message"). ADB is not yet active at this time so I can't use logcat or the shell on the device. Is there a way to set up anything on the device so I can write the messages to a logfile or the display of the device? I don't want to install a different bootloader, I would like to see the default bootloader "in action".

I'm using a rooted HTC Desire with S-OFF. Linux and Windows are available, communication to the device is possible via USB and WLAN. Other suggestions posted in this forum did not help (like this, if I add the suggested lines it just boots up normally. Or this, since I cannot use ADB).

Any help is very appreciated.

Best regards
