[MPC8272ADS]Problem adding flash partitions inside the device tree
Hi everybody !
I am currently trying to add the support of partitions for the Flash chip on
my MPC8272ADS board (the chips are Sharp LH28F016SCT-L90).
I have added this part:
fl...@0,0 {
compatible = jedec-flash;
reg = 0x0 0x0 0x200;
bank-width = 4;
device-width = 1;
partit...@ff80 {
label = kernel;
reg = 0xff80 0x0040;
read-only;
};
partit...@ffc0 {
label = user;
reg = 0xffc0 0x0030;
};
partit...@fff0 {
label = u-boot;
reg = 0xfff0 0x0010;
read-only;
};
};
But when I am compiling, I have these warnings:
Warning (reg_format): reg property in /local...@f0010100/fl...@0
,0/partit...@ff80 has invalid length (8 bytes) (#address-cells == 2,

Can anyone help me ?
I can't understand what the address-cells is.
Thanks in advance !

You are missing some definitions, The #address-cells and #size-cells = 1;
tis is a snippet of teh dts i defined for my board.
fl...@0,0 {
#address-cells = 1;
#size-cells = 1;
compatible = cfi-flash;
reg = 0x0 0x0 0x0800;
bank-width = 4;
device-width = 1;
/* set flash partition to correspond tu mtd parts in
u-boot*/
/* 0xf800 */
partit...@0x0 {
label = factory-image;
reg = 0x 0x0100;
};
/* 0xf900 */
partit...@0x0100 {
label = app-image-1;
reg = 0x0100 0x0100;
};

Hi do have these definitions, at a higher level:
The address-cells and size-cells definitions are not inherited. They
cover only the immediate children of the node where they appear.
Otherwise the default values apply (address-cells == 2, size-cells ==
1), which are not right for your case.

OK, so, after having tested, I can't see any changes when booting.
I do not have more mtd in /proc/mtd.

have you defined the following in your kernel config
CONFIG_MTD_PHYSMAP_OF=y
CONFIG_MTD_PARTITIONS=y
CONFIG_MTD_OF_PARTS=y
cheers pieter
I didn't have CONFIG_MTD_OF_PARTS=y.
Know, I have this output:

I think that the problem is in the reg part, but I can't understand why.
Isn't it the RAM mpping of my MTD that is the first address ?
Thanks agains,
