[U-Boot] Booting MX6 via Serial Download after DM conversion

[U-Boot] Booting MX6 via Serial Download after DM conversion

[Fabio Estevam]

Hi,

Has anyone managed to boot i.MX6 via serial download protocol after
the conversion to DM?

On a mx6sabresd I can no longer boot via SDP running 2019.04:

After running 'sudo ./imx_usb SPL' I get:

U-Boot SPL 2019.04 (Apr 22 2019 - 19:45:46 -0300)
Trying to boot from USB SDP
SDP: initialize...
SDP: handle requests..

Then I load the u-boot-dtb.img binary and the following error is seen:

$ sudo ./imx_usb u-boot-dtb.img
config file </usr/etc/imx-loader.d//imx_usb.conf>

With 2019.01 (prior to DM conversion) I can boot via SDP just fine.

Does anyone have any suggestions?

Honestly I am not familiar with imx_usb, we use mfgtool previously and not uuu tool.
Would you share where to download imx_usb and any doc,
Then we will debug this issue.

Thanks,

I 'think' the DM conversion requires the USB Driver to be defined as
UCLASS_USB_GADGET_GENERIC in order to be used as a peripheral.  I have
been following one of the TI boards [1] who's USB Driver has a bind
tool that go through the device tree and looks to see if the "dr_mode"
entry and then binds the appropriate driver (either HOST or GADGET).

I started a conversion on this, so I have a patch I can sent to
people, but I haven't gotten the GADGET side working, but I have a
binder function that then loads the host driver when "dr_mode" is set
to host.  I haven't had a lot of time to try and figure out the GADGET
side of things yet.  If someone wants me to send the a patch for what
I have so far, I can do that, but it only supports host mode.

I am fairly certain all gadget devices are broken on i.MX6 with DM_USB
enabled, so in SPL, I had to disable DM_USB in order to maintain the
SDP tool compatibility in SPL.

You can get imx_usb_loader tool from
https://github.com/boundarydevices/imx_usb_loader

Install it, connect the board in USB download mode and then:

sudo ./imx_usb SPL
sudo ./imx_usb u-boot-dtb.img

I suggest you to try U-boot 2019.01 first, which works fine and then
2019.04, which is broken.

I could get imx usb loader to successfully load 2019.04 if I manually
change the defconfig like this:

Is the UUU tool capable of loading SPL + u-boot-dtb.img generated from
mainline U-Boot for mx6sabresd?

Thanks

Not try this. 
uuu should support SPL file being loaded, then if SPL could runs into fastboot mode
to interactive with uuu, then u-boot-dtb.img could be loaded I think.

My colleague Breno tried to load SPL + u-boot-dtb.img using the UUU
tool and it also failed.

Could you please try to fix this regression?

Thanks

Things become complicated, there is no enough on chip ram for SPL DM, such as regulator/pinctrl/usb.

After check, it is not U-Boot issue, it is imx_usb should update to support new u-boot-dtb.img.

With your patch, file u-boot-dtb.img
u-boot-dtb.img: u-boot legacy uImage, U-Boot 2019.04-00664-gdbe9a81ff0\270, Firmware/ARM,
Firmware Image (Not compressed), 490914 bytes, Thu Apr 25 07:26:46 2019, Load Address:
0x17800000, Entry Point: 0x00000000, Header CRC: 0xCBE07038, Data CRC: 0x2C710405

without your patch, file u-boot-dtb.img
u-boot-dtb.img: Device Tree Blob version 17, size=1399, boot CPU=0, string block size=139, DT
structure block size=1204

Actually now u-boot-dtb.img is a FIT image with a device tree wrapper. So need fix imx_usb
to support both legacy and new image format.

Peng.

This issue also affects the UUU tool as well.

Is there a fix for UUU?

NXP software not enable SPL for this board, so I think UUU might not
support it. But UUU support SPL + FIT for i.MX8MM, uuu might work
for this board. I do not have time to check uuu side recently.
Let me check whether others have time on this.

Peng.

[Frank Li] If follow up i.MX8MM method, uuu needn't change.

imx_usb is doing some checking of the second binary it sends along?
That sounds odd to start with, is there some specific history there?
Thanks!

My understanding is that imx_usb_loader expects to find a valid IVT entry.

After the conversion to DM, a FIT image is used on
mx6sabresd_defconfig and such IVT can no longer be found, causing
imx_usb_loader to fail to loading u-boot-dtb.img.

It would be nice if we can come up with a solution, as loosing the
ability to load via imx_usb_loader has a negative impact for users.

Right, what I'm getting at is, why does imx_usb_loader need to find a
specific anything in the binary?  What is that IVT used for exactly?

fyi: we did see the same issue, look like FIT is incompatible with
these device boot scenarios even HAB failed (which I tried before)
with LOAD_FIT and OF_LIST.

You mean SPL FIT + HAB to verify U-Boot on i.MX6Q failed, right?

It needs some special handling to use SPL FIT HAB which is not supported in
upstream or vendor tree for i.MX6.

i.MX8M do have SPL FIT HAB in vendor tree.

Peng.
