Problem in flashing NSA325 u-boot

@bodhi
My device has different partition, The expected behavior was different from the guide.
When I'm deleting 4 blocks it only deletes one.

/e-data/4089-AD8E/tools # flash_erase /dev/mtd0 0 4
Erasing 128 Kibyte @ 60000 -- 100 % complete

now when I flash the uboot I get this

/e-data/4089-AD8E # nandwrite /dev/mtd0 kirkwood/generic/u-boot-nsa325/u-boot.kw

gendouhydeist,

> My device has different partition,

It does look the same. It is the stock definition which I did not change.

mtd0: 00100000 00020000 "uboot"

Did you check for bad block as instructed?

dmesg | grep -i bad

Don't shut down or reboot. Find out if you have bad blocks first and we'll go from there.

And one more question:

/e-data/4089-AD8E # nandwrite /dev/mtd0 kirkwood/generic/u-boot-nsa325/u-boot.kwb

Which u-boot is this you are trying to flash to your device? (it is not one that I released).

bobafetthotmail told me that I should use the one from LEDE snapshot, the one I'm using right now came from buildroot of LEDE.

The weird thing is that there's no bad block at all.

/e-data/4089-AD8E/tools # dmesg | grep -i bad
Scanning device for bad blocks

So you are installing LEDE?

Given your mtd0 is the correct definition, try to erase the whole partition:

flash_erase /dev/mtd0 0 0

Still the same though...

Ok I've used your uboot and it writes properly

/ # nandwrite /dev/mtd0 /e-data/4089-AD8E/uboot.2016.05-tld-1.nsa325.mtd0.kwb
Writing data to block 0 at offset 0x0
Writing data to block 1 at offset 0x20000
Writing data to block 2 at offset 0x40000
Writing data to block 3 at offset 0x60000

I check the env there's nothing there how I can put everything back?

/ # fw_printenv
Warning: Bad CRC, using default environment
bootcmd=bootp; setenv bootargs root=/dev/nfs nfsroot=${serverip}:${rootpath} ip=${ipaddr}:${serverip}:${gatewayip}:${netmask}:${hostname}::off; bootm
bootdelay=5
baudrate=115200

Should I load LEDE from RAM and start sysupgrade?
Follow the tutorial here http://forum.doozan.com/read.php?3,123813 to backup all stock partitions and install uboot (it also provides tools). The image that you must use is the "u-boot.kwb" one. Ignore the part of the tutorial about flashing envs manually, the LEDE uboot has them compiled in already.

This the link I refer to, please read the whole thread.
https://forum.lede-project.org/t/installing-lede-on-nsa325/3611/4

bobafetthotmail told me I should use the u-boot.kwb from LEDE instead of your compiled u-boot. He also told me that I should ignore installing env as LEDE provided it already.

Hi bodhi I have ask you few question...

After successfully flashing your uboot is it ok for me to restart my device? then setenv afterwards? wouldn't cause problems for me cause I haven't populate env's yet if I restart my device?

Yes, it would be OK.

No big problem, it will show the CRC error when u-boot tries to read the envs area. And then you can reboot and interrupt serial console, use the uEnv.txt capability to load the default envs in, and then adjust a couple variables to boot a Debian rootfs on USB , or HDD.

http://forum.doozan.com/read.php?3,12381

Quote

C. Add uEnv.txt to /boot directory

Create a text file in /boot directory with the content in the format that u-boot envs are listed.

Examples:

These 4 examples are only to demonstrate the syntax in uEnv.txt (they might or might not apply to your current settings):

- Load appropriate DTB file for the kernel to run GoFlex Net box.
- Use only USB drives for kernel and rootfs during booting
- Use SD card, USB and SATA for booting. The kernel and rootfs search order is as they are appeared on the list: mmc, usb, ide.
- Define that there are 8 storage devices (i.e. disk partitions).

cat /boot/uEnv.txt

dtb_file=/boot/dts/kirkwood-goflexnet.dtb
devices=usb
devices=mmc usb ide
disks=0 1 2 3 4 5 6 7
