Setting GPIOs in serial console (Kirkwood SoCs)
March 18, 2021 09:41PM
Power up the box, interrupt serial console. At the u-boot prompt.

First, dump the memory content of these 2 memory banks: GPIO0 address 0xF1010100 and GPIO1 address 0xF1010140

There are 32 GPIOs in each bank.
md.l 0xF1010100 1
md.l 0xF1010140 1

In the below example, we will set USB Power GPIO on the a Kirkwood box: for example GPIO 21. Note that each Kirkwood box likely has a different GPIO assigned to this USB Power, event though they are all in the same Kirkwodd SoCs family (the MPP pins are multiplex).

So we use the hex output of the first command (because GPIO 21 is in the 1st bank, GPIO0). We'll call it xxx.
md.l 0xF1010100 1

And then modify xxx to turn on the bit 21 (right to left, 0 to 31).

Set that bit 21 to 1. Do this temporarily on a notepad, and the result is yyy (in hex). See the end of this post for the bit mask layout in binary.

And then write the result yyy back to the memory address 0xF1010100

mw.l 0xF1010100 yyy

======

This example shows the layout of the bit pattern. The arrow below points to GPIO 29 being set.

GPIO0:

xxx = 0000 0000 0100 0010 0000 0000 0000 0000
yyy = 0010 0000 0100 0010 0000 0000 0000 0000

I have done this:

NSA320>> md.l 0xF1010100 1
f1010100: 10029000    ....
NSA320>> mw.l 0xF1010100 10229000
NSA320>> usb start
(Re)start USB...

NSA320>> ext2ls usb 0:1 /
** Bad partition - usb 0:1 **
NSA320>> usb reset
(Re)start USB...

       scanning bus for storage devices... 0 Storage Device(s) found
NSA320>> md.l 0xF1010100 1
f1010100: 10229000    ..".
NSA320>> ext2ls usb 0:1 /
** Bad partition - usb 0:1 **

So I checked whether a start or reset did not change the gpio 21 by displaying it with md.l and checked with ext2ls if it could read the partition (ext3), but it is still not working.

My calculation is right I think, it is basically (10029000 + 1<<21).

It should not affect it, but I am going to try it anyway and turn on gpio 15 as well (usb led), see if that will help. (EDIT: gpio 15 was already on, but the LED was not?!, is there some main switch in a gpio somewhere?)

It could be either: the USB power is not on, or this specific USB thumb drive is not recognized by this u-boot.

=======

It's been a long time ago that we worked on this box, it came back to me now certain GPIO on this box also needs to be controlled with clock (unlike most other Kirkwood boxes).


See the Wiki thread for how to set GPIO in Linux

Somewhere in the Debian working thread, we have specific example for this NSA320 box (I'll see if I can find it, or you can do advance search for all date).

I am getting this:
root@NSA320:~# /bin/echo 21 > /sys/class/gpio/export
/bin/echo: write error: Device or resource busy

If I read the link you gave well then it looks like gpio21 is not defined in the dts file, i am not able to write to this file. Do I have to create a .dts file somehow? I have looked for a .dts file that looks relevant for the NSA320, but I could not find one.

bandicoot,

Perhaps now is the appropriate time to install new u-boot and solve your problems once for all?

Right, and remember to run kwboot witht the new u-boot image first to make sure there is a rescue mechanism, before starting the installation.

The kwboot worked, I tried a boot as well, but that did not work because I had two rootfs's, one on ide and one on usb, it did find the usb-stick though ;), I only had to add -b to kwboot, because I used 64 version within fedora:
[root@localhost-live kwboot-tool]# ./kwboot -t -B 115200 /dev/ttyUSB0 -b uboot.2017.07-tld-1.nsa320.mtd0.kwb -p

Re: Setting GPIOs in serial console (Kirkwood SoCs)

bandicoot,

Your rootfs is still set up tp boot with stock u-boot. To boot the new u-boot (which is what you are booting with kwboot), the rootfs must be the original out of the box.

Quote
https://forum.doozan.com/read.php?2,12096

4. Create uImage with embedded DTB for booting with older u-boots (2012 or earlier). Do not do this step if you have installed the latest U-Boot for Kirkwood (or are installing this u-boot at the same time).

So the uImage must be reversed

cp -a uImage.orig uImage

Re: Setting GPIOs in serial console (Kirkwood SoCs)
March 23, 2021 04:58PM
I am getting confused in what the output of fw_printenv should be, it is a huge difference with the printenv from stock uboot.

I know the ethaddr should be set in the env, but I do not inderstand in which env, in the stock uboot or in where fw_printenv gets its settings from.

Also fw_printenv warns continuously the following: "Warning: Bad CRC, using default environment"

Is this default environment in the warning the one I should use? And should I somehow set ethaddr to the 'real' one which I find in stock uboot env?

I also did a a saveenv to get the stock uboot to boot my ide disk, this my current state.

If I flash the new uboot to mtd0, where do I save the env then?

Here is some output I collected:
# cat /etc/fw_env.config
# MTD device name       Device offset   Env. size       Flash sector size       Number of sectors

Because what you listed was the stock u-boot envs.

Ignore this, the rootfs is looking for the envs in a diiferent location from the stock envs location.

Find the real ethaddr either from stock envs, or on the box label (usually the bottom or back of the enclosure)

That was the stock envs location that you've saved to in serial console.

Step 8 in u-boot installation is when you will flash the default envs:

Quote

8. Flashing default u-boot envs image (if you are upgrading from 2016.05-tld-1 u-boot, you can skip this step 8).

After the default envs image was flashed, the fw_printenv and fw_setenv should work correctly. And within Step 8, some envs are adjusted further.

cd /boot
cp -a uImage uImage.with_DTB
cp -a uImage.orig uImage
sync

bodhi,

I did the copying in /boot end continued with the steps:

1.
# cat /etc/fw_env.config
# MTD device name       Device offset   Env. size       Flash sector size       Number of sectors
/dev/mtd0 0xc0000 0x20000 0x20000

2.
did the fw_printenv, but his was showing the default new uboot env fake ethadr.
But I do have the real ethaddr, I will add that later

3.
I did the nanddump to save mtd0

I also did the following:
# fw_printenv > current_envs.txt

But because of the default it is missing the mtdparts value (default new uboot env again), which is needed later on:

So all in all I have four questions:
- What should I set mtdparts to?
- Should I do the setting for SATA at step 8.e.3?
- Are values in /boot/uEnv.txt overriding existing values in flash?
- Can you see anything else that is blocking me from continuing with the next steps?

bandicoot,

Excellent!

> - What should I set mtdparts to?

mtdparts should have been in stock u-boot envs (it should show in printenv in serial console).

In Debian:
fw_setenv mtdparts 'mtdparts=orion_nand:0x100000(uboot),0x80000(uboot_env),0x80000(key_store),0x80000(info),0xA00000(etc),0xA00000(kernel_1),0x2FC0000(rootfs1),0xA00000(kernel_2),0x2FC0000(rootfs2)'

Note that the mtdparts is not important for booting. It's only used when you list and modifiy envs in Debian later.


> - Should I do the setting for SATA at step 8.e.3?

No need to do anything. It is optional. Only later when you want to use uEnv.txt then you would want to use this correcttion for the uEnv related envs. But of course it does not hurt to do it now.

The uEnv processing apply to all disks. But sometime SATA is a bit slow in reset the second time, that's why I suggested a "sleep 3" to make it go smoother.

> - Are values in /boot/uEnv.txt overriding existing
> values in flash?

Yes, but only temporary in RAM (not saved to flash). And you shoud not have uEnv.txt file in /boot unless you need to use it to change envs (whether just for experiment or really need to).

All look good.

bodhi,

Thanks for your quick reply.

I do have the mtdparts from stock uboot printenv in the following line, will these do then?:
bootargs=console=ttyS0,115200 mtdparts=nand_mtd:0x100000(uboot),0x80000(uboot_env),0x80000(key_store),0x80000(info),0xA00000(etc),0xA00000(kernel_1),0x2FC0000(rootfs1),0xA00000(kernel_2),0x2FC0000(rootfs2) root=/dev/nfs rw init=/init

then probably only this bit:
mtdparts=nand_mtd:0x100000(uboot),0x80000(uboot_env),0x80000(key_store),0x80000(info),0xA00000(etc),0xA00000(kernel_1),0x2FC0000(rootfs1),0xA00000(kernel_2),0x2FC0000(rootfs2)

And this was from my new uboot UART/serial kwboot, before I did all the steps 1 to 8.e.3 (steps ran with stock uboot boot into debian):

bandicoot,

Stock mtdparts:
mtdparts=nand_mtd:0x100000(uboot),0x80000(uboot_env),0x80000(key_store),0x80000(info),0xA00000(etc),0xA00000(kernel_1),0x2FC0000(rootfs1),0xA00000(kernel_2),0x2FC0000(rootfs2)

My mtdparts:
mtdparts=mtdparts=orion_nand:0x100000(uboot),0x80000(stock_uboot_env),0x80000(key_store),0x80000(info),0xA00000(etc),0xA00000(kernel_1),0x2FC0000(rootfs1),0xA00000(kernel_2),0x2FC0000(rootfs2)

They are the same, as far as the size and locaton are concerned. orion_nand is the new name for this flash driver in the latest kernel and stock_uboot_env is my naming convention to make clear what it is for furture reference. We don't use stock u-boot envs.

So use

mtdparts=mtdparts=orion_nand:0x100000(uboot),0x80000(stock_uboot_env),0x80000(key_store),0x80000(info),0xA00000(etc),0xA00000(kernel_1),0x2FC0000(rootfs1),0xA00000(kernel_2),0x2FC0000(rootfs2)

bodhi,

Thanks so much! I do have a working NSA320 with the new uboot now.
I did put the mtdparts definition into /boot/uEnv.txt and that is working fine.

My /boot/uEnv.txt nowlooks like this:
mtdparts=orion_nand:0x100000(uboot),0x80000(stock_uboot_env),0x80000(key_store),0x80000(info),0xA00000(etc),0xA00000(kernel_1),0x2FC0000(rootfs1),0xA00000(kernel_2),0x2FC0000(rootfs2)
devices=usb ide mmc
customparams=init=/bin/systemd


On to the next project, I would like to be able to turn on the fan, I already searched the forum and I could not find a working solution.

Is it default for the fan to be on? But then I don't know why mine is not.

I was able to turn off/on the led's, it looks like kirkwood-nsa320.dts caters for that. But the places where I could find the file, i was not able to find anything in it, nor in the inluded files, on traces of being able to turn the fan on or off using i2c or sensors.

Do you have any idea what I could try or maybe where else I could look for this?

It looks also that I fount a i2cset to be able to set auto-power-on after powerloss in:
https://forum.doozan.com/read.php?2,109139,109139
i2cset -y 0x0 0x50 0x06 0x01 b

Also I used wake-on-lan in stock firmware a lot, is there a way to set that too?

Cheers

That's quite clean, exactly how one should use this uEnv.txt!

For the mtdparts, you should set it permanently using fw_setenv, since it is not supposed to change.

I answered this on the other thread.

The i2c sensor reading/writing is not in the DTS. It's a Zyxel specific quirks.

Re: Setting GPIOs in serial console (Kirkwood SoCs)

bodhi,

I am continuing here, because this thread is about setting gpio's, only my case is not in serial.

I am able to run on my NSA320:
i2cset -y 0x0 0x50 0x06 0x01 b

But the ones for NSA326 I can't use, write error's:

According to https://forum.doozan.com/read.php?2,27108,106644#msg-106644
[WOL + AUTO RESUME]
If you want WOL + auto turn on after power loss:
/usr/sbin/i2cset -y 0x0 0xa 0xa 0x0006 w (ENABLE WOL)
/usr/sbin/i2cset -y 0x0 0x0a 0x0a 0x0107 w (ENABLE AUTO RESUME)

If I run it:
# /usr/sbin/i2cset -y 0x0 0xa 0xa 0x0006 w
Error: Write failed
/usr/sbin/i2cset -y 0x0 0x0a 0x0a 0x0107 w
Error: Write failed

So these NSA326 addresses are not for the NSA320.

Can I somehow convert the NSA326 commands to the NSA320? And could you point me in the right direction?

Cheers
