That is the issue I am describing here: https://lists.denx.de/pipermail/u-boot/2017-August/301952.html
Either enter recovery mode explicitly (by setting the BMODE pins or using the bmode command)
On imx6qsabresd it is not possible to put the boot pins into serial download mode.
Or you can use the USB PHY method which indicates whether the ROM used serial downloader. We use this in our downstream U-Boot (NXP used that method to go into "mgfr" mode...) http://git.toradex.com/cgit/u-boot-toradex.git/commit/?h=2016.11-toradex-nex... http://git.toradex.com/cgit/u-boot-toradex.git/commit/?h=2016.11-toradex-nex...
I have tested this method and it works, thanks.
Do you plan to usptream this method?
Thanks
