Yes, it has a power button.

What are the other options?

Unfortunately the stock boot log does not show the SPI flash chip name.

Some boxes don't use GPIO for power off or restart. Some boxes don't even have a power off. But there is a button here, so likely it is GPIO.

There is a section in drivers/mtd/spi-nor/core.c.

/* Flashes that can't be detected using JEDEC */
        {"m25p05-nonjedec"},    {"m25p10-nonjedec"},    {"m25p20-nonjedec"},
        {"m25p40-nonjedec"},    {"m25p80-nonjedec"},    {"m25p16-nonjedec"},
        {"m25p32-nonjedec"},    {"m25p64-nonjedec"},    {"m25p128-nonjedec"},

Since the jdec seems unrecognized by the kernel:

Quote

[ 5.737484][ T1] spi-nor spi0.0: unrecognized JEDEC id bytes: 1c 31 14 1c 31 14

One of those in the table might work. Most likely:

"m25p80-nonjedec"

The dts job seems to be done. After all the 'reboot' gpio 55 was the power-off gpio. Somehow it causes a reboot when activated from shell, but it powers down the box when shutting down. Maybe the combination with the blue system led which is on when up, but somewhere switches off during shutdown.

Now I can startup and shutdown the box using the same button. For some reason the 'POWER' button in esekeyd.conf didn't work, it had to be KEY_116.

Both ranges are 5087104 bytes in size, so I suppose the decompressor moves the compressed kernel from 0x000080C0 to 0x0119D200, and decompresses it back. According to binwalk the decompressed kernel is 18433664 bytes (there is an initramfs inside), so the address 0x0119D200 (18469376) should fit, but there is not much room left.

Yes, I recall some problem with how recent version of esekeyd deals with key names. I think it does not map that key KEY_116 to Power button correctly (other buttons also have same problem). But as you've found, using key number works fine!

Cool!

Did you use the SPI mtd dump for kwboot?

It must be because the wait logic is in the NIC. So it's gone when power is interrupted.

Nice! it makes sense (with its own battery).

While the RN102 uses loadaddr 0x2000000, The Mirabox uses loadaddr 0x6400000. Perhaps try 0x6400000 to see it will make any difference.

Well, there is no visible battery on the board, but I suppose the RTC is that low powered that it can keep the time on a capacitor.

At around 6% the speed slowed down, and after a minute it was at 8%. When you leave it, it stops at 21%. According to Willy the whole upload should take around 45 sec. Reading Willy's page, I think at 6% the DDR3 initialisation code was uploaded, and the box somehow slowed down a lot due to wrong timings.

So I tried to patch my own dump. Willy talks about 0x10000, but I don't know if that is 0x00010000 or 0x010000. When looking for 0x010000 I found a few occurrences, unfortunately not on the same addresses, but I patched them anyway. Problem is now that some checksum doesn't fit, I think:

kwboot -b spidump -p -a -t /dev/ttyUSB0
spidump: Invalid image.

So I can try to patch kwboot to correct it on the fly, or do you have a better idea?

You really don't need to strip anything, use the whole SPI mtd dump is better (no doubt if anything missing). It just a bit slower. After you can boot it with kwboot, you can tweak it to make it smaller.

Yes, it might be problematic because DDR timing of different boards.

kwboot has been substantially improved, much more robust than older versions.

In case you were running the kwboot on your box distro (which must be a few generation older), I've attached the ARM kwboot binary I've just built today. Please try this kwboot with the SPI mtd dump.

I'll be back, it's pretty late in my timezone :)

BTW, where did you compile this binary? I had to create a symlink /lib/ld-linux.so.3 to /lib/ld-linux-armhf.so.3 on my Debian box to get this running.

Meanwhile I have found the problem of the OpenWrt image. It's the patch target/linux/mvebu/patches-5.10/300-mvebu-Mangle-bootloader-s-kernel-arguments.patch, which has as comment
Quote

The command-line arguments provided by the boot loader will be
appended to a new device tree property: bootloader-args.
If there is a property "append-rootblock" in DT under /chosen
and a root= option in bootloaders command line it will be parsed
and added to DT bootargs with the form: <append-rootblock>XX.
Only command line ATAG will be processed, the rest of the ATAGs
sent by bootloader will be ignored.
This is usefull in dual boot systems, to get the current root partition
without afecting the rest of the system.

You could try Willy's recover.bin with the new kwboot. It might boot.

Note how Willy use the old doimage command. It's probably needed to produce the correct image.

I compiled it on the Thecus N2350 (Armada 385) box. That's strange, usually by default, compile u-boot tools natively will produce a static binary. And I run it on the NSA310S (Kirkwood Soc, which is armel) so there is no armhf share library on thix box. Let me see I can find out why.

Ah. Congrats! so that's where they patched it.

I was looking further at that patch. It adds a 'ARM_ATAG_DTB_COMPAT_CMDLINE_MANGLE' to Kconfig / .config. And in arch/arm/boot/compressed/atags_to_fdt.c, there is a code block disabled by this config:

#ifndef CONFIG_ARM_ATAG_DTB_COMPAT_CMDLINE_MANGLE
                else if (atag->hdr.tag == ATAG_MEM) {
                        if (memcount >= sizeof(mem_reg_property)/4)
                                continue;
                        if (!atag->u.mem.size)
                                continue;
                        memsize = get_cell_size(fdt);

                        if (memsize == 2) {
                                /* if memsize is 2, that means that
                                 * each data needs 2 cells of 32 bits,
                                 * so the data are 64 bits */
                                __be64 *mem_reg_prop64 =
                                        (__be64 *)mem_reg_property;
                                mem_reg_prop64[memcount++] =
                                        cpu_to_fdt64(atag->u.mem.start);
                                mem_reg_prop64[memcount++] =
                                        cpu_to_fdt64(atag->u.mem.size);
                        } else {
                                mem_reg_property[memcount++] =
                                        cpu_to_fdt32(atag->u.mem.start);
                                mem_reg_property[memcount++] =
                                        cpu_to_fdt32(atag->u.mem.size);
                        }

So this looks like the patch disables the pass through of the detected memory size to the kernel.

What I don't understand is, why is this code here anyway? AFAIK the atag data is in the first 0x8000 bytes. The piggyback + compressed kernel is put on 0x8000. So the decompressing piggyback could just not touch this area, and let the decompressed kernel handle it. If I now choose to not compress the kernel, this code is not attached, and so there has to be a second atag interpreter, or it's not allowed to have a not compressed kernel.

When looking in the OpenWrt wiki to bootlogs, I have the impression that most MIPS devices have the bootloader decompress the kernel, while most (all?) ARM devices have a decompressing piggyback on the kernel. The directory arch/mips/boot/compressed is much smaller than arch/arm/boot/compressed.

Maybe the atag blocks are handled by the piggyback, because it needs the memory size itself, somehow. When I look at the log with the patch removed

DTB:0x01673BD0 (0x00003402)
Uncompressing Linux... done, booting the kernel.
[    0.000000] Booting Linux on physical CPU 0x0

compared to start_kernel

asmlinkage __visible void __init __no_sanitize_address start_kernel(void)
{
        char *command_line;
        char *after_dashes;

        set_task_stack_end_magic(&init_task);
        smp_setup_processor_id();

the first bootline comes from smp_setup_processor_id(), which doesn't seem to do anything outside the stack, and set_task_stack_end_magic() only puts a marker at the end of the current stack, which is setup either by the bootloader, or by the piggyback. So when it crashes before this bootline, the crash is in the piggyback.

/Edit:
meanwhile I found that the patch disables this lines in function atags_to_ftd() in atags_to_fdt.c in the piggyback, which causes the crash.

               else if (atag->hdr.tag == ATAG_MEM) {

                        if (memcount >= sizeof(mem_reg_property)/4)

So now I have to try if providing the right memory size in the dtb file fixes this issue.

/Edit2: It does.

Congrats for figuring out this problem!

So the crash had nothing to do with the UART address, since EARLYPRINTK is not used. But the memory was wrong so the decompression crashed!!!

My personal preference is to let u-boot pass the right memory, and the kernel just ignore what's in the DTS. This is more flexible is you have full control of u-boot. OpenWrt does not need that flexibility, and it usually runs with stock u-boot.

You could try Willy's recover.bin with the new kwboot. It might boot.

It doesn't

Poor memory. Pushed too hard.

So I patched kwboot to patch the checksum of my patched dump:

$ ./kwboot -f -b  spidump.patched -t /dev/ttyUSB0

Indeed the uploaded u-boot is active.

Does the KD22 boot with my Mirabox image?

My guess is yes, but I don't know. The only information I have is that OpenWrt thread.

/Edit: After removing the 'read_only' tag from the u-boot-env partition in the dts file, I was able to change the environment using fw_setenv, the box still booted :) , and the environment change survived a reboot.

Cool! it will be very handly in testing certain u-boot images. Could you post the kwboot patch?

@bohdi: Do you apply any patches to your kernel regarding power off? I've read linux-5.10.7-mvebu-370xp-tld-1.patch, but as far as I can see it only adds dts files, and a disk led driver.
For some reason in OpenWrt I can switch off the box, but I can't switch it on again without powercycling. Tried in both 21.02.1 (Kernel 5.4.154) and master (5.10.90). While your kernel works fine (5.10.7). Same dts file, of course.

The difference from mainline is all in the patch. I'm very careful when I create the patch (a new source tree is used each build), so that's all I got.

I do recall in some boxes (don't remember which), a separate driver for Restart must be used, so perhaps OpenWrt has some differences regarding this.

# grep -i power_reset /boot/config-5.16.5-mvebu-tld-1
CONFIG_POWER_RESET=y
# CONFIG_POWER_RESET_BRCMKONA is not set
# CONFIG_POWER_RESET_BRCMSTB is not set
CONFIG_POWER_RESET_GPIO=y
CONFIG_POWER_RESET_GPIO_RESTART=y

Yep, that was it. I had to set
CONFIG_POWER_RESET_GPIO=y
(and so also
CONFIG_POWER_RESET=y)
