LS1012ARDB u-boot does not see eMMC

[christophe_schm]

Hi,

I try to free up both USB and SD card slots for other purpose.

For the moment I use QSPI for firmware (default way) and an external USB stick for boot partition and rfs.

I'd like to put now all firmware, boot partition and rfs on the embedded eMMC, it looks like big enough (4G).

My problem now is that when in u-boot stage, i cannot see any eMMC memory.

Of course correct set switches as this:

Also tried and did several mmc rescan and such commands in u-boot but device does not show up.

Started looking into u-boot configuration files since I simply did standard build using "flex-builder -m ls1012ardb" command and got all binaries done (here firmware for instance).

What am I missing? Do I need to rebuild my firmware or pass some special arguments in u-boot to see eMMC?

And: is my goal of putting firmware, bootloader and rfs all onto same eMMC memory device correct approach?

Thx Christophe

Hi yipingwang,

Here my full boot trace on eMMC: firmware .img from QSPI bank2, ubuntu:lite boot+rfs from eMMC now.

Let me know if you see someting strange or not correct but it looks good.

Thx Christophe

Hello Yiping,

In u-boot loading dtb into fdt_addr_r (located at 0x90000000) instead of fdt_addr (located at 0x00f00000) allows me now to boot the Linux. It breaks when attempting to mount the root fs but this certainly is due to fact boot partition tarball originates from a ubuntu:main and rfs from a ubuntu:lite.

So I am about to make a full clean build from scratch and reprog my eMMC partitions again with correct and matching images. Then this shall startup like a charm. Agree?

Thx Christophe

[christophe_schm]

Hello Yiping,

I am still stucked with the ubuntu:lite - since I need do this OFFLINE.

In parallel I do it ONLINE too with my other setup but OFFLINE is the final target for me!

So I start with a fresh build: "flex-builder -i clean" then "flex-builder -i clean-rfs", all cleaned.

That said I thought I can simply pick the tarball like this

chris@MOB13263:~/temp$ curl -R -O -k -f http://www.nxp.com/lgfiles/sdk/lsdk1909/rootfs_lsdk1909_LS_arm64_lite.tgz

-rw-rw-rw- 1 chris chris 195403698 Oct 18 13:07 rootfs_lsdk1909_LS_arm64_lite.tgz

Then copy out "rootfs_lsdk1909_LS_arm64_lite.tgz" into my OFFLINE system and put it into /build/images, just as I can do for the regular ubuntu:main RFS, right?

Then I try do a "flex-builder -m ls1012ardb -r ubuntu:lite - a arm64". Is that supposed to work?

My understanding is firmware, boot image and RFS must be built together so correct merge occurs between all this.

Finally I still have my problem with loading my DTB into $fdt_addr location and was looking into sources of u-boot components. I need to understand why this occurs in my case - did not find anything useful in this Community space unfortunately.

*** Reading file would overwrite reserved  memory **

Your help is much appreciated, thanks.

Ok tried to use "flex-installer -i pf" from TinyLinux to attempt to partition eMMC I can see now.

Thing is eMMC simply is too small for flex-installer - 4 Gbytes.

Looking at flex-installer script's function "check_disk_capacity" I understand at least 16 Gbytes are expected.

Changing partition sizes with -p option so I hopefully can squeeze into my 4G eMMC the tarballs won't change anything. For obvious reasons I'd say seeing tarballs size.

Therefore my question: what is eMMC supposed being used for on my LS1012ARDB board? As a bigger boot device instead of QSPI flash where my firmware will reside? Or also for a very small distro user land? Any hint welcome since I cannot see this in documentations ...

REMIND: I need my USB and SD card ports being freed up for other purpose. SATA is none of an option ...

Thx Christophe

[yipingwang]

Hello Christophe,

You could use ubuntu:lite filesystem, please generate rootfs_lsdk1909_LS_arm64_lite.tgz with the following commands.

flex-builder -i mkrfs -r ubuntu:lite

flex-builder -i packrfs -r ubuntu:lite

Please boot the target board to enter into Linux OS with SD/USB, please use the following commands to generate two MMC partitions, one for boot partition, another for rootfs.

$ fdisk /dev/mmcblk1

$ mkfs.ext2 /dev/mmcblk0p1

$ mkfs.ext2 /dev/mmcblk0p2

Please decompress bootpartition_LS_arm64_lts_4.19.tgz to mmcblk0p1 and decompress rootfs_lsdk1909_LS_arm64_lite.tgz to mmcblk0p2.

load mmc 0:1 $load_addr Image

load mmc 0:1 $fdt_addr <dtb file>

setenv bootargs "console=ttyS0,115200 root=/dev/mmcblk0p2 rw rootwait earlycon=uart8250,mmio,0x21c0500"

booti $load_addr - $fdt_addr

Thanks,

Yiping

Hi Yiping,

Ok I managed to do all this and ended up on my eMMC with two partitions

• 200M for boot partition
• 3.4G (what remains of eMMC) for RFS

I was able to copy and untar completely

• bootpartition_LS_arm64_lts_4.19.tgz into eMMC partition
• rootfs_lsdk1909_LS_arm64_main.tgz into eMMC RFS partition

Once untared with "tar xf" I removed original tarballs (*.tgz) to gain some space.

I've two small difference however vs. your sample code above

• Your partition names are /dev/mmcblk0p1 and /dev/mmcblk0p2
  • My partition names are /dev/mmcblk1p1 and /dev/mmcblk1p2
• In u-boot when doing a "mmc dev 1" my device appears as "mmc1" and not "mmc"

So with the eMMC correctly programed I now go into u-boot and stop there then do as instructed

• mmc dev 1
• setenv hwconfig esdhc 1
• load mmc1 0:1 $load_addr Image (the image, indeed on boot partitio, see it)
• load mmc1 0:1 $fdt_addr fsl-ls1012a-rdb.dtb (device tree blob, indeed on boot partition, see it)

• setenv bootargs "console=ttyS0,115200 root=/dev/mmcblk0p2 rw rootwait earlycon=uart8250,mmio,0x21c0500"

• booti $load_addr - $fdt_addr

After the last command above (booti) I get an error back: Bad Linux ARM64 Image magic!

I notice doing a "ls mmc1 0:1" for instance return empty data, no error neither.

I also noticed my eMMC no longer is visible in e.g. TinyLinux or on Linux I previously programmed on external USB stick (both Linux are still booting and working). eMMC simply disappeared from a Linux POV but not from a u-boot POV.

What am I missing, did I brick something here?

Thx Christophe

[christophe_schm]

Maybe I broke my firmware on my QSPI - about tor reflash since no way to see the eMMC anymore, neither in TinyLinux nor on regular Ubuntu Linux distro ...

Another thing I was thinking about: maybe during SCP operation where I bring in my tarballs on eMMC partitions I forgot to ensure transfer is done in BINARY mode and not TEXT ...

Pleas in the meantime if you've and idea here share with me, thank you!

Regs, Christophe

Hello Christophe,

Please load Image and dtb with the following command.

=>load mmc  1:1 $load_addr Image

=>load mmc   1:1 $fdt_addr fsl-ls1012a-rdb.dtb 

Thanks,

Yiping

[christophe_schm]

Hello Yiping,

Thank you, now I feel stupid, ok it's mmc and not mmc1 and first digit is device number and second partition.

Ok, I did this and the first line, when loading "Image" it goes well.

Second command however, where we load dtb, u-boot reports back:

*** Reading file would overwrite reserved  memory **

Keepi going and still entering new bootargs as you suggested then do the booti command and it tells (of course):

ERROR: Did not find a cmdline Flattened Device Tree

My u-boot variables are:

fdt_addr=0x00f00000

fdt_addr_r=0x90000000

load_addr=0xa0000000

Doing a "ls mmc 1:1", first and boot partition, and I can see files like "Image" and also "fsl-ls1012a-rdb.dtb".

Doing a "ls mmc 1:2", second and rfs partition, and I can see the complete RFS indeed.

I still have both tarballs (*.tgz) in both partitions, can I delete them to get some space back?

And, can I automate above said into a variable or u-boot script so I don't need to type this into u-boot shell?

Thx Christophe

[yipingwang]

Hello Christophe,

You could delete rootfs_lsdk1909_LS_arm64_main.tgz after untar the tarball.

You also could build ubuntu:lite rootfs with the following command, which is about 180M.
$ flex-builder -i mkrfs -r ubuntu:lite -a arm64 

In addition, you could configure bootcmd with the following command

=>setenv bootargs "console=ttyS0,115200 root=/dev/mmcblk0p2 rw rootwait earlycon=uart8250,mmio,0x21c0500"

=>setenv bootcmd "load mmc 1:1 $load_addr Image; load mmc 1:1 $fdt_addr fsl-ls1012a-rdb.dtb ; booti $load_addr - $fdt_addr"

=>boot

Thanks,

Yiping

[christophe_schm]

Hi Yiping,

Thanks for the automation hints, will get inspired from that very good!

Ok I understand that I shall go with a smaller RFS but if I want to keep the actual one (think it's the Ubuntu-based main userland) being about 700M of size, am I supposed to be able to start it up on my LS1012ARDB? The board has 1 Gbyte of RAM so that shall not be the issue. Or bootloader not reserving all the RAM so I can load by DTB?

Regarding eht Ubuntu:lite I understand I cannot build it under WIN10 OS + WSL, for that I need a native and real Linux running on a real host machine, ideally of Ubuntu 18.04.xx LTS version, right?

Thx Christophe

[christophe_schm]

Hello Yiping,

This is very good information, much thanks, let me test this now.

Will report back ASAP it's up and alive. Suppose for building RFS I need a real Linux machine? Will try w/ WSL on Windows or worst case within a Docker container.

Thx Christophe

[yipingwang]

Hello Christophe SCHMID ,

Please refer to the switch setting for EMMC.

Thanks,

Yiping

[christophe_schm]

Hello yipingwang‌

Maybe my question was not clear enough, sorry. Of course I already correctly set the switches as said in documents.

Here a pic of my board.

Thx Christophe

[yipingwang]

EMMC

Need to switch sw2[1,2]=01

And run the command of "mmc dev 1" to switch emmc mode in uboot

After Rev D board, the HW for board had some upgrtaded, so need to set the hwconfig in uboot to support the emmc and then run "mmc dev 1", and linux will to support the EMMC

setenv hwconfig esdhc1

[christophe_schm]

Hello yipingwang‌,

Ok that worked, thanks! I now can see this (both QSPI booted TinyLinux and regular Linux still being on my USB stick)

mtdblock0       31:0   0      64M   0   disk

mmcblk1        179:0   0     3.6G   0   disk

mmcblk1boot0   179:32  0       2M   1   disk

mmcblk1boot1   179:64  0       2M   1   disk

My question now: how shall I program my eMMC from that point now? From TinyLinux I'd say just as I did for my sda USB device before?

Thx Christophe
