Debian Installation on Thecus N2350 (Marvell Armada 385)

Hello,

I am also interested in running on my N2350 as the original FW lacks some software and some of them are outdated.
They also provided me the link to GPL source today :)
If I may help with moving forward I will be more than happy.

lordzahl,

Very good! I'll take a look later.

I am updating this post as I am reading the info from n2350_gpl.tar.gz.

1. The newer DTB that should be used for this Thecus N2350 box:

In the rootfs Debian-4.12.4-mvebu-tld-1-rootfs or in newer kernel linux-4.15.4-mvebu-tld-1:

./boot/dts/armada-388-db.dtb

2. The kernel config in In the rootfs Debian-4.12.4-mvebu-tld-1-rootfs or in newer kernel linux-4.15.4-mvebu-tld-1 should be enough (better) to boot this Thecus box.

3. USB power GPIO (and other GPIOs):

@nailman23: Happy to hear that others are interested. Do you have a serial console yet?

@bodhi: Okay, if i understand you correctly i should still use the dtb from your Debian/linux Images. We also do not need the kernel config. The only thing which is missing (at the moment) is the USB power.

So i was thinking, the dts, which is used for this box does indeed not enable USB power on boot. We can see that, since i was not able to boot the box with stock kernel and dtb from usb.
But there are other dts files for 385/388 processors, which show how to enable usb power. The talk about gpio pin 12 in gpio1 (there seem to be to gpio groups 0 and 1).
I'll attach the dts files to this post.
The armada-38x-modular.dts shows also how to power up USB via a "gpio expander".

Yes, I did implement USB power for the Zyxel NAS326. Each box is likely to have a different GPIO for USB power. For the NAS326:

armada-380-zyxel-nas326.dts

+                usb2_power: regulator@1 {
+                        compatible = "regulator-fixed";
+                        reg = <1>;
+                        regulator-name = "USB2 Power";
+                        regulator-min-microvolt = <5000000>;
+                        regulator-max-microvolt = <5000000>;
+                        enable-active-high;
+                        regulator-always-on;
+                        regulator-boot-on;
+                        gpio = <&gpio1 11 GPIO_ACTIVE_HIGH>;
+                };

So we can search the GPL for this number. If you found the code you think is right, please post.

There is no u-boot GPL in this tarball. That would be more helpful than the kernel source.

Ok found a whole bunch of GPIOs.

/* N2350 GPIO(MPP) Definition */
static const unsigned char FAN_TACH = 6;
static const unsigned char STAT_LED_WHITE = 14;
static const unsigned char STAT_LED_RED = 15;
static const unsigned char USB_LED_WHITE = 16;
static const unsigned char USB_LED_RED = 17;
static const unsigned char PWR_LED_RED = 18;
static const unsigned char HDD1_LED_WHITE = 19;
static const unsigned char HDD0_LED_WHITE = 20;
static const unsigned char USB3_PORT0_EN = 21;
static const unsigned char USB3_PORT1_EN = 24;
static const unsigned char HDD0_ATTACH = 26;
static const unsigned char HDD1_ATTACH = 27;
static const unsigned char PWR_LED_BLUE = 43;
static const unsigned char HDD0_EN = 44;
static const unsigned char HDD1_EN = 45;
static const unsigned char HDD0_LED_RED = 46;
static const unsigned char HDD1_LED_RED = 47;
static const unsigned char FAN_CTRL = 48;

static const unsigned char RESET_BTN = 50;

static const unsigned char USB_COPY_BTN = 52;
static const unsigned char USB_OVER_CURRENT = 53;
static const unsigned char PWROFF_CTRL = 54;
static const unsigned char TEMPERATURE_INT = 55;

Most likely this is what we are looking for to power the 2 USB ports:

static const unsigned char USB3_PORT0_EN = 21;
static const unsigned char USB3_PORT1_EN = 24;

Do you have a picture for this box that you can upload here? Is there a serial pinouts header?

Hi bodhi,
Great that you found the GPIO definitions.

I have linked an article with a picture in the first post.
But if still needed i can get pictures myself and upload them here directly.

It seems like J2 might be an unpopulated GPIO (20 pin)?
Cheers, Manuel

Hi Manuel,

I see I've missed that picture :) Looks like J1 is a 4-holes pinout? hope it is not a 4 solder buttons!

J2 looks like JTAG pinout (usually 20 pins).

hi bodhi,

Yes, J1 is a 4 hole pinout, which could be easily soldered and is used for the serial console by me at the moment. I just put some loose wires in these holes.
I'll attach a picture of the backside of the pcb to this post.

While I'm coding the DTS, I'd like you to try the kwboot again.

I can see why your kwboot was not successful with that error. Thecus u-boot is in SPI flash!

BootROM - 1.73

Boot into stock OS, and

cat /proc/mtd

That mtd "U-Boot-img" is where u-boot is. So do a dump (assuming it is mtdx):

dd if=/dev/mtdx of=mtd_uboot bs=1024k conv=sync

And then run kwboot again with this file mtd_uboot.

kwboot  -t -B 115200 /dev/ttyUSB0 -b mtd_uboot  -p

if that does not work, try

kwboot  -t -B 115200 /dev/ttyUSB0 -b mtd_uboot  -p  -s 0 -q 1

BTW, you might need to try running kwboot many times until you can get a handshake with the box.

@nailman,
Did you solder the wires or just temporaily connect them like lordzahl did?


@all,

That was actually some strange behavior, since we are kwbooting the same u-boot, but the output seems to be different.

BootROM - 1.73
 (Boot)
Booting from SPI flash

And the progress of image loading did not show after this:

Sending boot image...

So I think the handshake did not occur. Sometime this could be caused by the wire connections not stable. I have seen reports here about some member tried to hold the wires to the header during kwbooting and it seems to work more reliable! It could be that the xmodem protocol is more sensitive than the other normal serial protocol.

Here is the initial DTB version for testing.

Copy the attached DTB to your USB rootfs /boot/dts/ folder.

Power up, interrupt serial console and set the envs (note that I've changed the usb_bootcmd to not loading uInitrd). We want to ignore that for now and see if the USB drive is powered up OK first.

setenv load_dtb_addr 0x1000000
setenv load_initrd_addr 0x2900000
setenv load_image_addr 0x02000000
setenv dtbfilename armada-385-thecus-n2350.dtb
setenv usb_set_bootargs 'setenv bootargs "console=ttyS0,115200 root=LABEL=rootfs rootdelay=10 $mtdparts earlyprintk=serial"'
setenv usb_bootcmd 'echo Booting from USB ...; setenv fdt_skip_update yes; ext2load usb 0:1 $load_image_addr /boot/zImage; ext2load usb 0:1 $load_dtb_addr /boot/dts/$dtbfilename; run usb_set_bootargs; bootz $load_image_addr - $load_dtb_addr'

You might be right. I did try to hold the wires, but i did not get a (much) better result. Out of a few dozens tries i managed to get one time:

[kwboot]$ ../kwboot-x86_64  -t -B 115200 /dev/ttyACM0 -b mtd_uboot  -p 
Sending boot message. Please reboot the target...-

My serial console is actually realized with a teensy 3.0 mcu and a breadboard. Probably this makes it worse. Maybe i will solder a connector or wires to the pcb tomorrow.

This run is actually better. When this happen, immediately use the up arrow to recall the command and execute it again.

I did that and it ended in the exact same message. So it seems it at least got into the right mode, but the data connection is still pretty bad?

Next up: Testing the DTB (thanks!!)

Yes, it just stops/hangs. Nothing happens after that. Inputs have no result.
I tried a second time with the same result.

OK! I did not have any SATA node in the DTS yet. Will upload another version in perhaps 8hrs or so.

The bad Xmodem message occurs frequently with the Pogoplug V4. In some cases, it would take 20 tries to get a handshake. I've got reports that it took quite a few tries to get the WD My Cloud to handshake also.

Here is a modified DTB version for testing.

Copy the attached DTB to your USB rootfs /boot/dts/ folder.

Power up, interrupt serial console and set the envs (note that I've changed the usb_bootcmd to not loading uInitrd). We want to ignore that for now and see if the USB drive is powered up OK first.

setenv load_dtb_addr 0x1000000
setenv load_initrd_addr 0x2900000
setenv load_image_addr 0x02000000
setenv dtbfilename armada-385-thecus-n2350.dtb
setenv usb_set_bootargs 'setenv bootargs "console=ttyS0,115200 root=LABEL=rootfs rootdelay=10 $mtdparts earlyprintk=serial"'
setenv usb_bootcmd 'echo Booting from USB ...; setenv fdt_skip_update yes; ext2load usb 0:1 $load_image_addr /boot/zImage; ext2load usb 0:1 $load_dtb_addr /boot/dts/$dtbfilename; run usb_set_bootargs; bootz $load_image_addr - $load_dtb_addr'
usb start
run usb_bootcmd

Hi bodhi,

> Here is a modified DTB version for testing.
I tried it, but it hangs at the same position (Log at end of post). I double checked afterwards by diffing the dtb against the old one, that i actually tested your modified version. Just to be sure.

I will give kwboot another try later today.
Cheers, Manuel

Here is the DTS source. Perhaps you might be able to spot something I did was wrong.

Manuel,

Try removing the HDDs and boot with USB only.

And I am eager to see if you can try kwboot again.

Thanks for sharing the DTS. I will take a look this evening.
I have no HDDs attached at the moment. Only the USB Stick.

Couldn't wait and took a look into the dts. In the original boot log (with stock everything) the next lines are about nand flash.

[    3.550713] armada-nand f10d0000.nand: Initialize HAL based NFC in 8bit mode with DMA Disabled using BCH 4bit ECC
[    3.565269] NAND device: Manufacturer ID: 0xad, Chip ID: 0xdc (Hynix NAND 512MiB 3,3V 8-bit), 512MiB, page size: 2048, OOB size: 64

I then compared the nand flash sections of your dts and the dts from gpl sources arch/arm/boot/dts/armada-385-db.dts
gpl source:

			spi1: spi@10680 {
				status = "okay";
				pinctrl-0 = <&spi1_pins>;
				pinctrl-names = "defaults";
				spi-flash@0 {
					#address-cells = <1>;
					#size-cells = <0>;
					compatible = "mx25l3205d";
					reg = <0>; /* Chip select 0 */
					spi-max-frequency = <108000000>;
					spi-cpha;

					mtd1@00000000 {
						label = "U-Boot-img";
						reg = <0x00000000 0x00100000>;
					};

					mtd2@00100000 {
						label = "U-Boot-env";
						reg = <0x00100000 0x00010000>;
					};
				};
			};

			/*
			 * 1GB Flash via NFC NAND controller
			 * should be disabled when the board boots
			 * from SPI flash, since NFC shares the same
			 * pins with SPI0 and requires SLM-1358 jumper.
			 * However the u-boot DTB parser will
			 * handle this situation and disable/remove
			 * unnessesary devices according to board
			 * boot-up configuration.
			 */
			nfc: nand@d0000 {
				status = "okay";
				#address-cells = <1>;
				#size-cells = <1>;
				nfc,nfc-mode  = "normal";	/* normal or ganged */
				nfc,nfc-dma   = <0>;		/* 0 for no, 1 for dma */
				nfc,nfc-width = <8>;
				nfc,ecc-type  = <1>;		/* 4 bit */
				nfc,num-cs    = <0>;

				mtd0@00000000 {
					label = "ubifs";
					reg = <0x00000000 0x20000000>;
				};

From the commentary it seems, that the spi flash is on spi0 instead of spi1 and the spi flash uses a different controller than you specified (compatible = "mx25l3205d";)?
Also the NAND Flash seems to be connected by a NFC Controller and carries other option "nfc,...".

Compare to the parts of your dts:

			flash@d0000 {
				status = "okay";
				num-cs = <1>;
				marvell,nand-keep-config;
				marvell,nand-enable-arbiter;
				nand-on-flash-bbt;
				nand-ecc-strength = <4>;
				nand-ecc-step-size = <512>;

				partition@0 {
					label = "U-Boot";
					reg = <0 0x800000>;
				};
				partition@800000 {
					label = "Linux";
					reg = <0x800000 0x800000>;
				};
				partition@1000000 {
					label = "Filesystem";
					reg = <0x1000000 0x3f000000>;
				};
			};

&spi0 {
	status = "okay";

	spi-flash@0 {
		#address-cells = <1>;
		#size-cells = <1>;
		compatible = "w25q32", "jedec,spi-nor";
		reg = <0>; /* Chip select 0 */
		spi-max-frequency = <108000000>;
	};
};

Maybe some configuration error between these two causes the hang. Is there a way to get more verbose output in the kernel log?
Maybe i can answer some of these question myself tonight.
Cheers, Manuel
