I have pulled some patches/hacks into our tree to make SDP work, at least without DM [2]. If someone could come up with a proper solution for upstream that would be great and I would be happy to review/test.

It looks just like yours except that I have a single instruction as already stated above: /path/to/image/u-boot.itb:load 0x40200000, jump_direct 0x40200000 and I'm loading the FIT image by running './imx_usb' without arguments. As imx_usb_loader can't parse FIT image headers, I use 'jump_direct' to jump to the raw image entry point and let SPL parse the FIT. I think in that case imx_usb_loader shouldn't complain about a missing header. ^ permalink raw reply [flat|nested] 22+ messages in thread

I think in > that case imx_usb_loader shouldn't complain about a missing header. Frieder, Ok, I finally understand. Using 'imx_usb <file>' which is what I was doing is not the same as loading it via the conf file and was why it was looking for a header. So now that I'm using the imx_usb.conf files fully instead It's loading u-boot.itb and jumping but unfortunately I'm still not quite there. Here's what I'm seeing: U-Boot SPL 2020.01-00029-g6529a03-dirty (Apr 09 2020 - 13:02:21 -0700) Normal Boot Trying to boot from USB SDP SDP: initialize... SDP: handle requests... Downloading file of size 584020 to 0x40200000... done Jumping to header at 0x40200000 Header Tag is not an IMX image Is the 'Header Tag' message normal? From adding some debugging it appears to matching the dts name in my board_fit_config_name_match and parsing the FIT image, loading the ATF and jumping but then I get nothing. What would I expect at this point and do you have any troubleshooting tips? Thanks, Tim ^ permalink raw reply [flat|nested] 22+ messages in thread

Do you have the patches I submitted to enable USB OTG in general on IMX8MM? usb: ehci-mx6: add IMX8MM and IMX8MN OTG support usb: ehci-mx6: move mode set/detect to probe I would like to get those patches accepted and I think there was some concern that 'usb: ehci-mx6: move mode set/detect to probe' may break gadget support.

* Re: iMX8MM USB support? 2022-03-09 10:52 ` Michael Nazzareno Trimarchi @ 2022-03-09 11:06 ` Tommaso Merciai 0 siblings, 0 replies; 22+ messages in thread From: Tommaso Merciai @ 2022-03-09 11:06 UTC (permalink / raw) To: Michael Nazzareno Trimarchi Cc: Tim Harvey, Schrempf Frieder, u-boot, Peng Fan, Fabio Estevam Hi All, In these days I'm working on SDP_SPL support on iMX8MM, thanks to Tim that guide me over the following patches: https://patchwork.ozlabs.org/project/uboot/list/?series=251796&state=* I'm able to reach the goal to boot U-Boot 2022.04-rc3 over SDP from SPL. I would like to suggest that at the current state of the project you need to add also the following configs: CONFIG_SPL_USB_HOST=y CONFIG_SDP_LOADADDR=0x40400000 Using that I'm able to boot the U-Boot 2022.04-rc3 with the following .lst file: sudo uuu file.lst file.lst ------------------------------------------------------------------------ uuu_version 1.2.39 # This command will be run when i.MX6/7 i.MX8MM, i.MX8MQ SDP: boot -f flash.bin # These commands will be run when use SPL and will be skipped if no spl # if (SPL support SDPV) # { SDPV: delay 1000 SDPV: write -f flash.bin -skipspl -offset 0x0 SDPV: jump # } FB: done ------------------------------------------------------------------------ I hope this can help some other person.
