flash_erase, nandwrite & nanddump with openwrt
November 03, 2020 04:06PM
Hello. I have another Pogoplug V4 that I bought used and that doesn't boot, so I was going to install your uboot & openwrt.

I was able to get to the CE boot loader from a serial console, then loaded openwrt via tftp and booted it. I'm now logged in to openwrt, but I'm trying to figure out how to do flash_erase, nandwrite and nanddump. Not finding those utilities on openwrt. I tried downloading the executables for those that I've used on other Pogos under the original Pogo OS, but I get "not found" when I try to run them, so assuming there is a missing dynamic library that they use.

Is there a different version of those utilities somewhere I can install or download?

I do see a "mtd" command. Is this what I should use instead?

Any help/suggestions appreciated.

Ralph

I think I found what I need - nand-utils package. I installed it, but I'm getting permission denied error:

Quote

root@OpenWrt:/tmp# flash_erase /dev/mtd0 0 4
flash_erase: error!: /dev/mtd0

root@OpenWrt:/tmp# ls -l /dev/mtd0
crw------- 1 root root 90, 0 Jan 1 1970 /dev/mtd0
root@OpenWrt:/tmp#

This is what current mtd partitions look like:

Quote

root@OpenWrt:/tmp# cat /proc/mtd
dev: size erasesize name
mtd0: 001c0000 00020000 "uboot"
mtd1: 00040000 00020000 "uboot_env"
mtd2: 07e00000 00020000 "ubi"

and I set /etc/fw_env.config to this

Quote

root@OpenWrt:/tmp# cat /etc/fw_env.config
/dev/mtd1 0x0000 0x40000 0x20000

but apparently that's not right because fw_printenv isn't happy

Quote

root@OpenWrt:/tmp# fw_printenv

is it marked read-only in your device tree?

How do I see my device tree? Just ls -l /dev/mtd0, or something else?

Because you've flashed my u-boot image, the envs area must be:

/etc/fw_env.config 
# MTD device name	Device offset	Env. size	Flash sector size	Number of sectors
/dev/mtd0 0xc0000 0x20000 0x20000

And since OpenWrt embedded the DTB in uImage, it is read-only. So you need to set mtdparts in bootargs to make it writeable. If not sure, please post the entire serial bootlog with a listing of envs in serial console, 

printenv

and I'll guide you how to do that.

OTOH, if you are running stock u-boot, then the envs are at a different location.

Hi Bodhi. I haven't actually flashed your u-boot yet. I was trying to do the flash_erase so I could do that.

I'm assuming it's running the Cloud Engines uboot because uboot prompt is "CE>". But not sure everything on this device is still stock - I bought it used and when I got it it wouldn't boot to the original OS. And notice /proc/mtd doesn't look normal, at least not what I've seen on other Pogos.

So I was thinking if I did flash_erase, then nandwrite for your u-boot and environment images, and then set fw_env.config to what you have above, I should be able to set the rest of my environment variables, including mtdparts and partition so there are just 2 mtd partitions. Then set netconsole variables, reboot, load and boot openwrt from uboot again, then sysupgrade to write openwrt to nand. Let me know if I'm heading down the wrong path.

But I didn't get very far. Couldn't do flash_erase.

Ralph,

Instead of using OpenWrt commands, download my tools tarball.

U-Boot flashing utilities:

https://forum.doozan.com/read.php?3,27280

Extract it and execute the binary directly: 
./tools/flash_erase /dev/mtd0 0 4

As I said, OpenWrt system might have disallowed writing to mtd0. So I need to see your serial console log with the printenvs output.

Same "not found" error as with the other one I tried.

Assuming missing some dynamic library.

Do I need to do the flash erase from within the CE u-boot?

Or should I just go back to CE u-boot and send you printenv output?

Not dynamic library. Those tools binaries are all static.

You have not flashed anything, so the CE stock u-boot is still on mtd0.


BTW, try moving the tools folder to the root 

cp -a /tmp/tools /mnt

and execute it there 

cd /mnt/tools
./flash_erasse ....

so on.

I rebooted into CE u-boot. Here is printenv.

Go ahead and boot into OpenWrt and post the boot log here.

OpenWrt normally has the uboot mtd set to read only so you can make a backup but not modify it. I guess that is done to avoid people bricking their devices. So you would have to change the dtb or compile a custom openwrt to be able to update uboot. It may be easier to boot into bodhi's Debian from an USB stick instead and update uboot from there.

Hmm, interesting. That explains the permission denied error.

How do I boot from USB using the original CE u-boot? I see diskboot command to boot from IDE, but don't see anything for USB.

If I copied the uImage from a bodhi Debian USB stick (or SD card, which is what I use to boot Debian on my Pogos), and used tftpboot and bootm to load and boot it, would it be smart enough to find the root file system on USB or SD card?

No need to do that. We only need to change bootargs to overide the DTB. This is the normal booting procedure for all my Kirkwood u-boots.

But it is best to follow the installation procedure for the Pogo V4 here from the Wiki thread:

@Ralph,

Please try the above installation if you can still boot to stock OS. Note that the procedure mention netconsole, and you have serial console so you can skip the netconsole connection, and then it is exactly the same.

Bodhi,

I've never been able to boot to the original OS on this Pogo.

If I manually load and boot your uImage from CE uboot via tftp, will it find the MMC or USB root file system and come up?

If not, plan B is to try to recompile openwrt with MTD_WRITEABLE=1. But if you think plan A will work, I'll try that first.

Well, not having a lot of luck getting openwrt to compile...

Decided to go ahead and try manual load/boot of bodhi's kernel. Pogo went from blinking green to solid green, but not seeing it come up on the network. Console log is below. Note that I am using an older 3.18.5 kernel that doesn't use a dtb_file.

On the outside chance rootfs on MTD1 is OK, and the only reason it wouldn't boot stock OS was because of some environment variable problem (I have no idea what the previous owner did to it before I got it), is there a command/commands I can run from CE uboot to try to boot into the old OS?

Ralph,

I hate reinventing the wheel :) so here look at this tftp boot example and see what you did differently:

https://forum.doozan.com/read.php?3,28772,29034#msg-29034

The above instruction uses Debian-4.4.0-kirkwood-tld-1-rootfs-bodhi.tar.bz2, but you can use the latet rootfs (Debian-5.2.9-kirkwood-tld-1-rootfs-bodhi.tar.bz).

Once you boot into Debian rootfs, then anything is possible.

Woohoo! It's up! I plugged the SD card into a USB reader and put that into the Pogo.

The other stuff I did was set mtdparts and partitions back to the way they were before, and added root=LABEL=rootfs and rootdelay=10 to bootargs. I'm guessing root=LABEL=rootfs may have been key.

THANK YOU VERY MUCH!
