Linux/AM5718: AM5718 usbboot on TMDXIDK5718

Part Number: AM5718
Other Parts Discussed in Thread: TMDXIDK5718,

Tool/software: Linux

hi,

I am using EVM TMDXIDK5718. I  wanted to try out usbboot. For this purpose I have modified USB1 from host to device mode.

I have configured sysboot pins to enable usbboot.

I have tried the steps provided in link

I  could execute till following command "'host$ sudo usbboot-stand-alone -S spl/u-boot-spl.bin""

Here in I get the following response on minicom

""

U-Boot SPL 2018.01-00558-gca1e85ecb5-dirty (Feb 18 2019 - 14:29:39)
DRA722-GP ES2.0
Trying to boot from DFU
Using default environment

port 0 can't be used as device                                                  
board usb init failed

""

AS i understand i could dump and execute usbspl to AM5718. But from there on these is no response.

What  is the issue?? Why is usb init as device failing?? Pls respond

  • Referred the following thread https://e2e.ti.com/support/processors/f/791/t/701775?Linux-AM5728-DFU-support-on-IDK.  Included the patch as suggested.




    I guess I was able to download u-boot Image but could not execute uboot image .

    Pls let me know how to proceed further

    Attaching sceen shots.... both host prints and mincom prints captures....

  • Hi Rakesh,

    The Processor SDK v5.x U-Boot doesn't support DFU boot for AM57x devices. Please follow the e2e thread linked below (sorry it is a long thread) to understand how to modify U-Boot use to DFU boot on AM57x. Mainly there are two patches needed.

    1. Modify USB1 from host to device mode;

    2. Fix UBoot so that SPL can locate the downloaded UBoot image.

    e2e.ti.com/.../730514

    Please also follow the training video linked below for how to use DFU Boot.

    8306.am57xx_evm.hHi,

    i have applied the following  patches :

    1) 0001-usb-enable-usb1-device-mode-for-am57x.patch.txt

    2)  0002-configs-am57xx_evm-define-CONFIG_SPL_LOAD_FIT_ADDRES.patch.txt

    as mentioned in the above thread

    but it seems that the u-boot.img still cant start.

    I am getting the same message on minicom :

    ""U-Boot SPL 2018.01-00558-gca1e85ecb5-dirty (Feb 21 2019 - 11:28:08)

    DRA722-GP ES2.0

    Trying to boot from DFU

    Using default environment

    ################DOWNLOAD ... OK""

    Ctrl+C to exit ...

    I guess as u suggested still SPL cannot locate u-boot img.... I am attaching the screen shots of minicom & USB host print....and files patched

    I checked am57xx_evm.h you attached, but it doesn't have patch 0002. Please ensure you applied both patches properly.

  • I attached both patches here for your reference.

    Also configure usb2 to host mode. The dr_mode in board usb2 dts node has
    to be set to "host" to use usb2 in host mode.

  • Hi, I haven’t heard back from you, I’m assuming you were able to resolve your issue. If not, just post a reply below (or create a new thread if the thread has locked due to time-out). thanks.
  • Hi,
    After applying the suggested patch we were able to execute uBoot.
    1. In the patch why should i configure usb2 to host mode ??. Any specific reason to configure so.
  • Rakesh,

    Glad to hear the issue is solved.
    As far as I know, the U-Boot USB driver only supports one peripheral port and one host port. So since USB1 is peripheral port now, we want USB2 to be a host port; otherwise, if both ports are peripheral or host, it could lead to unexpected behavior in U-Boot.
