Hi Marek, Paul, cc: Alex jFYI/FWIW, reverting [1-2] allows getting rid of below warnings on R-Car3, when running basic fastboot commands (e.g. fastboot getvar):
[ 8.035764] status: -104 ep 'ep1' trans: 0 [ 18.744354] status: -104 ep 'ep1' trans: 28 [ 18.748950] status: -104 ep 'ep1' trans: 9 [ 18.753370] status: -104 ep 'ep1' trans: 28 [ 26.064761] status: -104 ep 'ep1' trans: 28 This has been pointed out by Dmytro (To:) in one of his patches which reached us via official Renesas release. Since R-Car USB gadget driver is not yet present in mainline [3], the behavior cannot be reproduced with vanilla U-Boot. In case, at some point in time, you hit the same problem and come to the same or an alternative solution, please share. TIA!
