ZOOM2 doesn't boot on upstream kernel

ZOOM2 doesn't boot on upstream kernel

[Neshama Parhoti]

Hi all,

I can't get to boot the latest mainline kernel on ZOOM2 (using
omap_zoom2_defconfig).

It just hangs after u-boot is saying "loading kernel...".

I know that my setup is ok, because if I use TI kernel sources from my
BSP it boots fine..

Any idea what is the problem ?

Maybe I need to use also recent upstream u-boot ?

thank you

[Ghorai] It's working for me. 
1. console=ttyS0
2. And can you try omap3_defconfig

it's good to hear !

This is what I see:

## Booting image at 81c00000 ...
   Image Name:   Linux-2.6.35-rc3-00001-g945a7eb
   Image Type:   ARM Linux Kernel Image (uncompressed)
   Data Size:    2409672 Bytes =  2.3 MB
   Load Address: 80008000
   Entry Point:  80008000
   Verifying Checksum ... OK
OK

Starting kernel ...

Uncompressing Linux... done, booting the kernel.

(and then nothing happens, you don't even see the penguin on the screen)

> 1. console=ttyS0

are you sure ?  all TI's docs state ttyS2 (and this works for me with
TI's BSP kernels)

but since I don't see the penguin on the screen, I don't think this is
the problem

btw I see there is CMDLINE in the .config, and also boot cmds that I
pass via uboot.. I wonder if they should be the same..


> 2. And can you try omap3_defconfig

it doesn't compile:


arch/arm/mach-omap2/built-in.o: In function `ads7846_dev_init':
linux-2.6/arch/arm/mach-omap2/board-omap3stalker.c:542: undefined
reference to `omap_set_gpio_debounce'
linux-2.6/arch/arm/mach-omap2/board-omap3stalker.c:543: undefined
reference to `omap_set_gpio_debounce_time'


I'll see what I can do about it...


thank you !

Its ttyS0 if the omap serial driver is compiled in. The omap driver
takes the ports instead of the 8250 driver.

you are absolutely right !!!!!!!

i changed it to ttyS0 and now I get the boot msgs ! :)


can you please check out my whole boot args to see if i have any other error ?

just to make sure..

setenv bootcmd 'tftpboot 0x81C00000 /srv/tftp/uImage; bootm 0x81C00000'
setenv nfsdata nfsroot=192.168.1.4:/home/pnesh/myfs,nolock,devfs=mount
ip=192.168.1.160
setenv bootargs console=ttyS3,115200n8 root=/dev/nfs rw rootdelay=1
mem=256M init=/init videoout=omap24xxvout
omap_vout.video1_numbuffers=4 omap_vout.vid1_static_vrfb_alloc=y
${nfsdata}


thank you a lot !!

The penguin on the screen won't come up, since I don't think that the nec panel drivers for DSS2 has been merged in mainline.

The latest patch to get this driver is found here:

Re: ZOOM2 doesn't boot on upstream kernel

[deepthi]

Hi,

We are trying to boot 35 kernel on zoom2,I tried with android_zoom3 config and
choosing MACH as zoom2 and also with omap_zoom2_defconfig, kernel is not booting
at all,it is struck after 
Starting kernel ...

Uncompressing Linux...
 done, booting the kernel.

I have taken the omap4 panda release kernel for gingerbread.
Image name it is showing as Linux-2.6.35.7-00371-gcfb80c7-di

Please let me know Which kernel we have to take for zoom2 35.
I have tried with following bootargs
setenv bootargs console=ttyS3,115200n8 mem=256M  root=/dev/mmcblk0p2 rootdelay=1
init=/init omap_vout.video1_numbuffers=6 omap_vout.vid1_static_vrfb_alloc=y
omapfb.vram=0:4M
I even tried with ttyO3 also.
What should be the exact console should it be ttyO0?
Please help me out to come out from this issue

Can you please enable CONFIG_DEBUG_LL and CONFIG_EARLY_PRINTK
in your .config? Then also append earlyprintk to the bootargs
above. Then you should see more info on what goes wrong.

I'm suspecting you should use ttyS0 as the console instead
of ttyS3? That's at least what I have on my zoom3 board
with the extra debug board.

You should use ttyO for the omap ports, but zoom debug board
has external 8250 ftdi ports, so those show up as ttyS and
not ttyO.

Tony

Plus that was changed on 2.6.36 (or after?) and he is using 2.6.35.

RE: ZOOM2 doesn't boot on upstream kernel

[Deepthi Kiran]

Thanks for ur response,

Iam using omap 3430 processor for the custom board, for 32 kernel  tty port of console was ttyO3 only, I have enabled DEBUG_LL also, and I am using putc function of uncompress.h file to print early prints. Iam suppose to work on the custom board in which UART address and data lines are made reverse, so if the address is 0x01 then I need to send address as 0x04 and simillary data, so I can not use direct early prink . So in the putc function, Iam reversing the address and data and trying to print. Control is not even coming up to start_kernel of init/main.c,I think after uncompressing and relocating of the kernel, it is struck..
I tried directly on zoom2 board also, noting was happening. One more thing I observed was I used Panda configuration and changed MACH_ZOOM3 and tried on zoom3 board, kernel at least booted on zoom3 board.
Do we have any specific 35 kernel tested for zoom2 or zoom3, if so please let me know the path..
