Summary: parallel flash partition problem on bf561

Details:

current parallel flash partition on bf561:

sing physmap partition information

Creating 3 MTD partitions on "physmap-flash.0":

0x00000000-0x00020000 : "Bootloader"

0x00020000-0x00100000 : "Kernel"

0x00100000-0x00800000 : "RootFS"

And when flashing vmImage and rootfs into it,it looks the earlier environment params values are lost:

And in last release, the partition for uboot is:

0x00000000-0x00040000 : "Bootloader"

Follow-ups

--- Mike Frysinger 2008-02-05 19:58:31

it really doesnt matter to me what the default partition map is ... at the

moment, it's mostly a copy and paste from other boards. if 0x40000 for u-boot

is easier for you, it can be easily updated.

how about this ... what would be a good map for you ? 256k for u-boot, 768k

for the kernel, and the rest for the rootfs ?

--- Mingquan Pan 2008-02-13 02:55:32

Since 561 ezkit has 8M flash, we can give 256k for

u-boot,1792k(0x00040000-0x001fffff) for kernel,the rest for rootfs.

Plus question,the partition size for u-boot on bf537/533 is 128k, how to get a

u-boot smaller than that? with disable debug dump info, the u-boot still has

131k.

--- Mike Frysinger 2008-02-13 15:12:11

ive increased u-boot on bf561 to 256k

i dont know what you're looking at, but the default bf537 u-boot.bin is 120802

bytes and after disabling the debug info, it's 110304 bytes which should easily

fit inside of 128k default partition

--- Mingquan Pan 2008-02-14 05:10:16

So we need to shink rootfs partion for u-boot, I would like bf537 stamp board

partions like:

Creating 4 MTD partitions on "physmap-flash.0":^M

0x00000000-0x00040000 : "Bootloader"^M

0x00040000-0x00120000 : "Kernel"^M

0x00120000-0x003f0000 : "RootFS"^M

0x003f0000-0x00400000 : "MAC Address"^M

bf533 stamp board:

Creating 3 MTD partitions on "BF5xx-Flash":^M

0x00000000-0x00040000 : "Bootloader"^M

0x00040000-0x00120000 : "Kernel"^M

0x00120000-0x00400000 : "RootFS"^M

bf561 ezkit board:

Creating 3 MTD partitions on "physmap-flash.0":^M

0x00000000-0x00040000 : "Bootloader"^M

0x00040000-0x00200000 : "Kernel"^M

0x00200000-0x00800000 : "RootFS"^M

bf548 ezkit remains at:

Creating 3 MTD partitions on "physmap-flash.0":^M

0x00000000-0x00040000 : "uboot"^M

0x00040000-0x00200000 : "kernel"^M

0x00200000-0x00600000 : "rootfs"^M

Would you update svn partition like above?

I would modify test script then to have a test.

--- Mike Frysinger 2008-02-14 14:14:02

the 4 boards should have a 256k partition for u-boot now in trunk

--- Mingquan Pan 2008-02-15 03:00:36

Partition size updated.Close.
