uBoot bootargs are missing and can't boot

[ddB0515]

Opening this issue for making together uBoot bootargs as after rescue kernel and uBoot are flashed to SPI NAND device can't boot standalone
There is already some people in issue #5 that have same issues and this is not resolved

I have extracted from original SDK bootargs

setenv bootargs console=ttyS0,115200 ubi.mtd=UBI,2048 root=ubi:rootfs ro rootfstype=ubifs init=/linuxrc rootwait=1 LX_MEM=0x3f00000 mma_heap=mma_heap_name0,miu=0,sz=0x1a00000 mma_memblock_remove=1 highres=off mmap_reserved=fb,miu=0,sz=0x300000,max_start_off=0x3300000,max_end_off=0x3600000 $(mtdparts)
setenv bootcmd ' bootlogo 0 0 0 0 0; mw 1f001cc0 11; gpio out 8 0; nand read.e 0x22000000 KERNEL 0x500000; gpio out 8 1; bootm 0x22000000;nand read.e 0x22000000 RECOVERY 0x500000; bootm 0x22000000

And as we don't need most of this stuff we would need new one that will make us boot normally

1st issue I got in uBoot is no support for nand access and we have to do it with ubi so original will not be a lot of help
If you query from uBoot ubi info

UBI: MTD device name:            "UBI"
UBI: MTD device size:            125 MiB
UBI: physical eraseblock size:   131072 bytes (128 KiB)
UBI: logical eraseblock size:    126976 bytes
UBI: number of good PEBs:        1002
UBI: number of bad PEBs:         0
UBI: smallest flash I/O unit:    2048
UBI: VID header offset:          2048 (aligned 2048)
UBI: data offset:                4096
UBI: max. allowed volumes:       128
UBI: wear-leveling threshold:    4096
UBI: number of internal volumes: 1
UBI: number of user volumes:     5
UBI: available PEBs:             0
UBI: total number of reserved PEBs: 1002
UBI: number of PEBs reserved for bad PEB handling: 18
UBI: max/mean erase counter: 2/1

So we can see UBI just need to adjust some things as is suggested in #5 by @fifteenhex but I don't know how to save in this case
I have tried sf probe0 and saveenv but that just frooze and did nothing

Also do we need to separate bootcmd and bootargs? or we could use it as one?

[fifteenhex]

You just need to load the kernel into memory from ubi and jump to it.
If the ubi command is detecting your ubi device correctly you can use it to load the kernel from the right partition.

I don't think sf is meant for spi nand.

bootargs is you kernel commandline. You should tell it what to mount as root there.
bootcmd should be the ubi command to load the kernel into memory and bootm it.

saveenv should work too. But maybe if you use the sf command it breaks things.

[ddB0515]

I have tried with sf and without it just freeze on saveenv so that is not working as intended to
Also how I can debug that I can save uBoot args and load automatically without need to do manual entry?

As I have tried this

setenv bootargs console=ttyS0,115200 ubi.mtd=1 ubi.block=0,4 root=/dev/ubiblock0_4 rootfstype=ubifs rw rootwait=1 ip=none
setenv loadaddr 0x22000000; ubi readvol ${loadaddr} kernel 0x800000; bootm ${loadaddr}

But it hangs when needs to load

I have tried rootfs as squashfs also but it didn't work as you can see example up is for ubifs that I have added to config

+BR2_TARGET_ROOTFS_UBIFS=y
+BR2_TARGET_ROOTFS_UBIFS_LEBSIZE=0x1f000
+BR2_TARGET_ROOTFS_UBI=y
+BR2_TARGET_ROOTFS_UBI_SUBSIZE=2048

and uploaded via recovery and load it via ubiupdatevol but still won't boot
all what it does is freeze but interesting part is that from logs you can see it is created

[    2.885457] block ubiblock0_4: created from ubi0:4(rootfs)                   

[fifteenhex]

Can you see if you can read out the rootfs you've written in the rescue image?
Comparing the output between the rescue image and where it gets stuck might help too.

[ddB0515]

So I have managed to update kernel to support ubifs as was not supporting it from your config (maybe to add it to config?)
can make PR later if this succeeded :)

CONFIG_UBIFS_FS=y
CONFIG_UBIFS_FS_ADVANCED_COMPR=y
CONFIG_UBIFS_FS_LZO=y
CONFIG_UBIFS_FS_ZLIB=y
CONFIG_UBIFS_FS_ZSTD=y
CONFIG_UBIFS_ATIME_SUPPORT=y
CONFIG_UBIFS_FS_XATTR=y

and now I can mount it in rescue mode

so I'm certain that ubifs image creation is valid and works as it should
But still didn't get or succeeded to get load kernel and rootfs :(
Always freeze and there is not so difference in logs

[fifteenhex]

Stick clk_ignore_unused into your bootargs.

[ddB0515]

OMG that WORKED

SOM2D01 now can boot stand-alone without issues with this

setenv bootargs console=ttyS0,115200 ubi.mtd=1 rootfstype=ubifs root=ubi0:rootfs rw clk_ignore_unused init=linuxrc
setenv loadaddr 0x22000000
setenv bootcmd ubi readvol ${loadaddr} kernel 0x800000; bootm ${loadaddr}
saveenv

Thanks a lot for help but curious why do we need that clk_ignore_unused to get it work?
And I'll write detailed procedure from start to finish (with ubifs)
do you want it as Wiki or should I create new tutorial as md file?

[fifteenhex]

Thanks a lot for help but curious why do we need that clk_ignore_unused to get it work?

At the line it was getting stuck the kernel is disabling clocks of hardware it thinks are unused. If a clock is actually being used that can cause the system to lock up. Right now we need that because we don't have a perfect clock driver that knows the complete clock tree and the dependencies. That parameter should be in the bootargs in the devicetree but if you override the bootargs from u-boot it's needed there too.

should I create new tutorial as md file?

Create an MD file so it's part of the repo

[ddB0515]

Closing as is resolved and will all be documented in md file soon
