sdhc support

[epinter]

A1600 kernel sources doesn't appear to be complete ... I can't find mmc_core.c or mtd drivers ...

Halftux, did you tried A1600 mmc's driver? This one could maybe work better on your cards, than muromec one ??

Sorry i only could try binaries... but here on A1200, my sdhc did work and the normals microSD's too...

I don't understand, but now, for looking at moto's code, i only try to read latest A1200e LATAM sourcecode!!
I see a /driver/i2c/a780_camera.c here in this tree? Don't know, i'm quite embarrased with compilations for A910 for now... and don't support spending too much time to on motorola's semi-released code, you know...
It's a little more clean and also compatible with quite all ezx device (except a1600, i guess... Of course with some usuals stuff forgotten but both for the happyness and the sadness of the reader )

My first compiled kernel with muromec's sdhc patch it's up and running in my A1200i with A1200e hybrid firmware (my version of special edition, I will release it soon...)

My 1GB card it's working perfect, but I don't have a 4GB card to test (yes, I will buy one)...
Somebody can help testing it ?

This is not for end users yet... It was tested with only one phone (mine)...

Please, before flashing be sure your "language" filesystem is at the same position and size as below:
(As far as I know, all A1200e except the ORIGINAL widgets firmware have this addresses).

# cat /proc/roflash_info
ROFLASH Driver status: Ready

ROFLASH area name is rootfs
ROFLASH area size = 27254784 bytes
ROFLASH area offset = 6295552 bytes
ROFLASH area l_x_b(10)
ROFLASH area name is language
ROFLASH area size = 11534336 bytes
ROFLASH area offset = 28180480 bytes
ROFLASH area l_x_b(1000)
ROFLASH area name is data_resource
ROFLASH area size = 10485760 bytes
ROFLASH area offset = 1703936 bytes
ROFLASH area l_x_b(1000)
ROFLASH area name is setup
ROFLASH area size = 131072 bytes
ROFLASH area offset = 6160384 bytes
ROFLASH area l_x_b(10)
ROFLASH area name is secure_setup
ROFLASH area size = 122880 bytes
ROFLASH area offset = 26873856 bytes
ROFLASH area l_x_b(1000)

The language filesystem it's just a reference, the A1200e mappings are different from other versions ...

@muromec
Thank you for sharing you sdhc patch with the community.

WOW again, i will look like an awfull code leecher, but... could you post the patchs, too?

[epinter]

I used the patches from muromec, available in this thread ...

The work I made was remap the address of roflash and MTD areas in LATAM kernel to be able to use it with standard A1200e firmware (like R541L7_G_11.00.1AR). I will post the patch (it's very simple) when this kernel is tested and work on more then 1 phone...

Ok, thanks you very much!!

My kernel is working with SDHC patch and usb storage working:

Hi all,
I need help adding the patch in tmr tmp_do (U3 jffs2).
Replacing the CG33 don't work.
Please if someone know, please share info.
Thanks

extract patch file with ezxcodec and ur f/w which u want to sdhc support.Now copy patch files in smg of ur f/w.AND then compile


thats it

LOveysingh,
You have not understood, patch and kernel are two different things...

[Halftux]

When you want to add this to tmp_do firmware. You need to compile the kernel with sdhc patch and also activate jffs2 and loop support for the kernel.

CONFIG_JFFS2_FS=y
CONFIG_BLK_DEV_LOOP=y

Maybe you need to edit the config cmdline and change the rootfstype to jffs2.
But I realy dont know if this is everything what you need to do never tried this and I dont know the firmware. Take also care of the mtd map.
The best is if you have the modified kernel source from tmp_do.
Good luck my friend.
