sdhc support

[muromec]

seems something sucks.

[sabrod]

Yeah, i requested an updated kernel source tree to moto...

[sabrod]

vmlinux15 , vmlinux1, vmlinux10 , vmlinux12, vmlinux3, won't boot here on my a1200
(with good batteries, no sd card, and unplugged of the computer's usb or charger)
Should i do something else before / after flashing this?

btw, i used "bootusb flash 0xa0000 sdhc-qtopia-kernel-to-flash" instead of flashcp, but added the required 0x800 bytes' offset...and if i go back to a backup i made (bootusb read 0xa0000 0x100000 backup) then it reboot fine.


I have the last "test" fw from 06/03...

[muromec]

this is strange. try simply boot kernel with boot_usb and login via ssh

[sabrod]

Sorry, i was googling...
bootusb method: the screen is going crazy (some scrached screen, then some lcd garglings flashes, splitted in 4 horizontals divisions)...
with sdhc15 kernel, should i try ssh ing on this junk ?
Or try another build?

[sabrod]

i'll try ssh-ing...
(OT) it seems my 2.4 compilations for A910 is auto powering off the phone... I'll review my mtd layout as it seems there is such function on the cfi NOR flash driver.

[sabrod]

ssh works!!! But well, the screen is just "funny"
8Go sandisk SDHC mount and list the files OK!! ... i didn't made more test, because i'm on low batt, and I'm also concerned about the lcd garglings !!! lol
dmesg shows :

mmc_media_transfert: request past end of partition
end_request: I/O error, dev f3:02 (mmc), sector 0
FAT: unable to read boot sector
jffs2: attempt to mount non-MTD device f3:02

[...]
long list of

sdhc address fix

I'm from flash mode, so I also have the:

MUX DLCI:0 Send SABM timeout!

On sdhc 15... wtf ?
f3:02 > is the 2nd part of SD... i have only one part on this 8gig sdhc!


here is a 2nd vmlinux-sdhc15' dmesg with another sd (non sdhc):

>bootusb method: the screen is going crazy

its normal

>here is a 2nd vmlinux-sdhc15' dmesg with another sd (non sdhc):
>T[125]if_cond failed 19 (ERROR_TIMEOUT)

Damm! AGGRH! don`t know what to do with this

>i didn't made more test, because i'm on low batt

you can manually turn charging on with hwtool -c 4 7

so kernel works and you can flash it to mtd. maby you missed something first time

>f3:02 is the 2nd part of SD... i have only one part on this 8gig sdhc!

mmca2 can be somewhere in fstab

[sabrod]

Well, hex-editing the file before flashing it shows me the kernel start at 0x800...
I used boot-usb each time with all sdhc kernels i tried...

I'll use the flashcp method next time, but i'm a little confused... Even the backup/rewrite works!

(the good point i see, is that maybe my a910 kernels works !! As i flashed them the same way and they does boot "loop" or stuck to the bootlogo... )

Do you have a gen2 pach to remove the big logo, and see the console at boot-time ?

>I'll use the flashcp method next time, but i'm a little confused...

i`m using this to update kernel on phone:

flash_kernel() {
 dd if=/dev/zero of=/tmp/mtd bs=1048576 count=1 
 dd if=$1 of=/tmp/mtd bs=2048 seek=1 conv=notrunc
 boot_usb flash 655360 /tmp/mtd || return

 rm /tmp/mtd

}

flash_kernel vmlinuz

no
