uuu with google coral dev board, SPL: Unsupported Boot Device 12

[synaption]

I am trying to get UUU working with the google coral devboard that is based on the imx8mq. I can get fastboot to work, but this would be a pain for bulk flashing. I am using buildroot which generates imx8-boot-sd.bin as the uboot binary, verified working in emmc with fastboot. the error I get with uuu is:

U-Boot SPL 2022.04 (Aug 29 2022 - 13:29:54 -0500)

SPL: Unsupported Boot Device 12
SPL: failed to boot from all boot devices (err=-6)
### ERROR ### Please RESET the board ###

The output on the host device is as follows:

Thanks nxpfrankli. What version of uboot are you referencing? I do not see this in mainline uboot or imx uboot's board/freescale/imx8mp_evk/spl.c. When I add this to common/spl/spl.c, I get a build error. If I understand correctly, I think I need to add values for these variables to include/spl.h as well?

imx8mp! not imx8mq. I was looking at the wrong board. Anyway. I added #include <asm/mach-imx/boot_mode.h> and that allowed the code to compile, but this did not change my error message. I even tried to force the function to return BOOT_DEVICE_BOARD; This caused the output of spl_loader_name() to change, so I can tell spl_board_boot_device() is being called, but spl_ll_find_loader() still returns 0 so my error persists.

[nxpfrankli]

Here is major for UUU host side issues. You'd better post uboot issue in nxp community. https://community.nxp.com/. There are more uboot expert to help you. or post into uboot's maillist.

[synaption]

Is there any chance I will have better luck with a winusb based transfer? How would I go about doing that.

[nxpfrankli]

You have to pass this phase, let SPL receive uboot firstly by SDP.

you can check common/spl/spl_sdp.c, make sure SPL_LOAD_IMAGE_METHOD("USB SDP", 0, BOOT_DEVICE_BOARD, spl_sdp_load_image);

NEW ERROR! exciting. I added a lot of include/config/imx8mq_evk.h to include/config/imx8mq_phanbell.h, as well as adding a lot from board/freescale/imx8mq_phanbell/imx8mq_evk.c to board/google/imx8mq_phanbell/imx8mq_phanbell.c. It seems like everything that should compile does. Now the process hangs at the following:

before SDP: handle requests... lsusb shows Bus 001 Device 105: ID 1fc9:012b NXP Semiconductors i.MX 8M Dual/8M QuadLite/8M Quad Serial Downloader. I am trying to use sudo uuu CFG: FB: -chip imx8mq -vid 0x0525 -pid 0x0151 to add recognition for the usb gadget as it seems to appear.

[lznuaa]

There are config to control USB VID and PID. You can reuse NXP one.

CONFIG_USB_GADGET_VENDOR_NUM=0x1fc9 CONFIG_USB_GADGET_PRODUCT_NUM=0x0152

I remember SPL Production_Number is CONFIG_USB_GADGET_PRODUCT_NUM - 1

Suppose your uuu is quit old.

0x0525 0xb4a4 actually is wrong PID/VID, which already register.

cfg only used for in uuu script. System will forget it after run uuu cfg: FB: ....

[synaption]

With A LOT of hacking, I have been able to make something work. CONFIG_USB_GADGET_VENDOR_NUM seemed to effect the right value, but CONFIG_USB_GADGET_PRODUCT_NUM did not do anything unless I changed it directly in the c code. Ultimately what I am able to do is this:

sudo uuu SDP: boot -f SDPVimx8-boot-sd.bin
sleep 1
sudo uuu SDPV: write -f mendel-imx8-boot-sd.bin -skipspl
sudo uuu SDPV: jump
# ums 0 mmc 0 # on coral
sudo bmaptool copy --bmap sdcard.img.bmap sdcard.img.xz /dev/sdb
# fastboot 0 # on coral
fastboot flash bootloader0 imx8-boot-sd.bin

So I basically used my uboot to start SDPV, then I load the original mendel linux uboot to use fastboot and ums. The last problem I am having is that I would rather run fastboot and ums with uuu FB: ucmd but the mendel uboot automatically boots into fastboot, and I need to use the serial terminal to press ctrl-c. Is there a way to press ctrl-c with ucmd?
