It does appear to be possible with u-boot: load mmc 0:1 $fdt_addr_r $fdtfile fdt addr $fdt_addr_r fdt set /soc/aips@50000000/usb@53f80000 dr_mode host Since the user would have to manually select the appropriate .dtb anyways, it may be reasonable to drop the host_mode.dtb and rely on the u-boot to tweak the fdt on boot to switch between usb modes. It is considerably more complicated than setting the fdtfile variable to the desired .dtb, as various out-of-the box boot scripts will load the .dtb file defined in the fdtfile variable, overwriting any changes made with "fdt set". Given the additional complication in boot scripts, my preference would be to ship both .dtb files...

Given that it is possible to set from u-boot, I'm wondering if it wouldn't be worth reworking the patch to only generate a single .dtb for now, and revisit the options for switching between USB host mode and peripheral mode later? live well, vagrant [-- Attachment #2: signature.asc --] [-- Type: application/pgp-signature, Size: 818 bytes --] ^ permalink raw reply [flat|nested] 10+ messages in thread

The board can switch between host and peripheral mode without any hardware modification, but it need to reboot itself to pick up the corresponding dtb file. I am not sure if there is possible using the devicetree overlay feature to switch between the two modes runtime.
