1. Building kernel for ADP1

Hello group moderator,

I apologize in advance if my question is without merit.  I am trying
to rebuild the kernel for an ADP1. I want to port a touchscreen
driver.

I am cross developing on a linux-x86 platform running Ubuntu.

I downloaded and built the latest android platform using the
instructions at source.android.com/download and source.android.com/
documentation/building-for-dream using the latest instructions for
donut.

I have searched the web and sent a direct question to HTC, for concise
instructions for building a new kernel for the ADP1.

I have purchased and received an ADP1 just last week (Oct 09)

I have downloaded the htc phone kernel source from <developer.htc.com/

I have downloaded the .config file from the phone.

I have noticed in the phone .config, that it used kernel version -.25
vs. -.27 in the msm_defconfig in the kernel source.

I placed the htc kernel source tree into ~/mydroid.  I copied the
phone .config to the kernel root.

I added the toolchain path "home/tes/myfroid/prebuilt/linux-x86/
toolchain/arm-eabi-4.4.0/bin" to my .bashrc and rebooted. After
reboot, echo $PATH shows the toolchain in the PATH.

I then ran the sequence:





The make failed trying to compile board-trout.c:
  CC      arch/arm/mach-msm/board-trout.o
arch/arm/mach-msm/board-trout.c:391: error: 'H2W_UART3' undeclared

'trout_h2w_data')
make[1]: *** [arch/arm/mach-msm/board-trout.o] Error 1
make: *** [arch/arm/mach-msm] Error 2

Did I miss some steps?

Thanks and best regards.

Kevin

2. gdbserver android patch

I might have posted this to a wrong group. Posting to the kernel
group. With some hacking, I could able to get the gdbserver to the
link with bionic libraries and run on my target (armv7) platform. But,
I see that the gdbserver can only trace ARM code not thumb code.  Then
I looked at the ptrace code in kernel and saw that it doesn't support
using breakpoints for the thumb code.

See arch/arm/kernel/ptrace.c
printk(KERN_WARNING "ptrace: can't handle thumb mode\n");

Question: Did anyone used gdbserver to single step thumb/thumb2 code?
