Looks good.
But in theory the envs should have been like this allready at first boot.
Dead Battery maybe ?

Edit:
Ok. Battery seems to be for RTC only.

OK. Please remind me :) if we have tried to flash the mtd0.dns-320-short to mtd0 in serial console during kwboot? if we have not, I think we should do that.

OK I saw the previous post:

https://forum.doozan.com/read.php?3,69499,74079#msg-74079

But it looks like we should try again. 

setenv mtdids 'nand0=nand_mtd'
setenv mtdparts 'mtdparts=nand_mtd:0xc0000@0(uboot)ro,0x7f00000@0x100000(root)'
mtdparts
fatload usb 0:1 0x800000 /mtd0.dns-320
nand erase 0x0 0x100000
nand write 0x800000 0x0 0x100000
The above was not quite right.

setenv mtdparts 'mtdparts=nand_mtd:0x100000@0(uboot),0x7f00000@0x100000(root)'

fatload usb 0:1 0x800000 /mtd0.dns-320-short
nand erase 0x0 0x100000
nand write 0x800000 0x0 0x100000

If the size of mtd0.dns-320-short is exactly 1MB.

We tried to flash mtd0.dns-320 which is 1MB ( 1.048.576 Bytes )
So far im just using the mtd0.dns-320-short for a faster kwboot ^^
Size is just 475,2 kB ( 475.216 Bytes )

> You can tell I already forgotten what progress we've made! too many things on the brain cells :))

I hear ya on this one ^^

Edit:

Post from Page 3 ^^

https://forum.doozan.com/read.php?3,69499,74029#msg-74029

Edit2:

When i flash the Nand, the Envs get resetted to defaults.

Stock env was wrong. This is the corerct version 

setenv mtdparts 'mtdparts=nand_mtd:0x100000@0(uboot),0x7f00000@0x100000(root)'


So 
setenv mtdids 'nand0=nand_mtd'
setenv mtdparts 'mtdparts=nand_mtd:0x100000@0(uboot),0x7f00000@0x100000(root)'
mtdparts
fatload usb 0:1 0x800000 /mtd0.dns-320
nand erase 0x0 0x100000
nand write 0x800000 0x0 0x100000

That's expected.

Does this box has SPI flash?

The behavior is like the BootROM does not know there is a NAND device in the system. Or it is set in hardware register (SARs) to look only to other device such as SPI for u-boot image.

When we kwboot the image, the BootROM detect something coming from UART (it always looks at UART first), handshakes with kwboot, and then only receive image data from UART.

Strange thing is why does it work with the original NAND ( despite the fact that the Chip needs freezing to Boot )
But not with the new one of exactly the same Type/Name/size? When flashing obviously seems to work?

The box runs differently when uboot is from kwboot and when from NAND.

The BootROM does not care if there is a NAND device, if it is executing UART uboot.

Ironaxe,

Do this test to confirm.

kwboot, interrupt serial console, and chain load the uboot in NAND: 

nand read.e 0x0 0x100000 0x800000
go 0x800200

Make sure you have these important NAND-related envs set like previously, before reading 

setenv mtdids 'nand0=nand_mtd'
setenv mtdparts 'mtdparts=nand_mtd:0x100000@0(uboot),0x7f00000@0x100000(root)'

Better yet, do 

mtdparts
And then try the chain load.

Please post the log with printenv.

So that gave you 5 blocks.

:) Hackish solution:

You could shorten the backup mtd to 512K (4 blocks). And flash only 4 blocks. Very good chance that this old u-boot is less than 512K. 

fatload usb 0:1 0x800000 /mtd0.dns-320-short-512
nand erase 0x0 0x100000

Cool!

Wooh. That was quite a chase to get NAND working :))

Apparently your new NAND chip has some problem on that 6th block.

So now I guess you should flash 4 blocks, and fill the rest with ff or 0.

And if that does not allow booting from NAND, change mtdparts to: 

mtdparts=mtdparts=nand_mtd:0x80000@0(uboot),0x7f00000@0x100000(root)

Re: UART Boot DNS-320 B1 with broken NAND
March 06, 2019 04:37PM
So we know that

- First 4 blocks of NAND is working fine storing the uboot image from another good DNS-320 B1 box.
- We execute that image and it runs normally. During running, we can see NAND mtds and access mtd0.

The question is back to whether the BootROM recognized the NAND device.

Unfortunately BootROM is closed source, we don't know exactly where it went wrong. This is the reason when people trying to kwboot different boxes and have to guess the timing for the handshakes. A lot of works went into making kwboot smarter to get it boot smoothly.

I recall there is a bunch of SATR registers from reading the 6281 ref manual. IIRC one of them can be used to set the boot device.

And this uboot has a SatR command. I think it might allow us to control the registers, but please try 
SatR
SatR list bootsrc

Theory:
Perhaps when you replaced the NAND chip, the boot source value got wiped out and set back to default.

UPDATE:

I think it was reset to SPI as boot source.

OK let's decipher that.

The default internal pull up is 0x4.

Quote
Reference Manual for 88F6281
Bits[14:12] = Boot device

Boot Device values

0x0 = Reserved

0x1 = Reserved

0x2 = Boot from SPI flash (SPI_CSn on MPP[7])
0x3 = Reserved

0x4 = Boot from SPI flash (SPI_CSn on MPP[0])
0x5 = Boot from NAND flash

0x6 = Boot from SATA

0x7 = Boot from the PCI Express port

00e2d26e = 0b111000101 101001001101110

Bit 0 is right most.

That's 101 = 5.

Was I correct?

Thats a little too high for me ^^
But 101 = 5 is right *lol*

But does the 6182 equals the 6702 ?
According to the "so called" Datasheet it aint got SPI but the LaCie Cloud Box has SPI Flash with this CPU

00e2d26e is the content of the location f1010030 

Marvell>> md 0xF1010030
f1010030: 00e2d26e 00000001 00000001 00000000    n...............
f1010040: 00000000 00000000 00000000 00000000    ................

That hex value 0x00e2d26e translated into binary is 
1110   0010  1101   0010    0110   1110

Bit 0 is right-most. 

1110   0010                   1101                    0010    0110   1110
                           bit 15-12 are here

So the value tells us that in that SatR register, the boot device = 0x5 = NAND.

So the conclusion must be that the NAND flash controller did not find the NAND device, or could not read from that.
