1 year ago @Insei Hi, Insei, I come to here again is to tell you that I got the TegraBoot messages from headphone port!!!
Congratulations!
These messages came from the ROM from Dargons10， looks like from the nvboot.bin and tos.img, maybe not the kernel.
Sorry, I don’t know exactly how the kernel is configured in Dragons10, but by default on the kernels for our device, UART is disabled. I don’t remember exactly how to enable it on all kernels, I only know that UART is enabled in this kernel.
But if you are thinking of starting to develop this krenel, then you should know that 3D graphics, cameras, sound, touch screens, some power regulators, charging, i.e. do not work. Almost everything doesn't work.
Plus, this kernel requires a TOS with PSCI version 0.2, rather than version 0.1, which is used in all ShieldTablet-based firmware, otherwise you may encounter freezes and other problems. But when using TOS with PSCI 0.2, all shield-based android/kernel/recovery will stop loading or will hang, i.e. these TOS are not compatible.
All I can help you with is sharing the boot image with recovery, and TOS with psci 0.2. boot_image.zip tos_0.2.zip

Its so cool~
It just happed after I bought a new USB2TTL connector to replace the old one. You may rememered that I have made some effort on doing that and expecting it will works but failed due to the computer can't receive any data from the phone.
(Additional, I found that we can tweak the device in more simple way, only applying pin connect in two place, pin4 and pin5，pin8 and pin9， the uart and headphone then bradged)
TegraBoot messages now showing on my computer screen, thanks for the new connector "Future Technology Devices International, Ltd FT232 Serial (UART) IC"

Based on this progress, config PRINTK is enough? I don't know, I set all these but messages stops there like mentioned above, whatever it can enter SysUI or not.
may be I still should apply this change?

Or apply this in "system/core/rootdir/init.rc" to add a log redirect? I dont known but I will test it.
Thanks god, thank you for your ideas and advices~
