Hi Marek & Lukasz,
I have an issue running fastboot on my board (which is
USB_SPEED_HIGH):
=> fastboot0
failed to enable in ep
failed to enable in ep
failed to enable in ep
Because of this, fastboot does not even initialize properly, and I
need to "^C" to break out…
I have traced this the following code in
"drivers/usb/gadget/dwc2_udc_otg.c":
I will have to delegate this onto Lukasz, since he's the s3c gadget
expert.
Take a look at:
[PATCH 1/2] usb: gadget: s3c_udc_otg: fixed max packet size check
for ep_in in high speed
Best regards,
Marek Vasut
yes - I think that 'patchwork.ozlabs.org/patch/560029' would resolve
my issue
Thanks, Steve
Ok, I see the point. The above patch should not bring any regression,
since if MPS < maxpacket(ep), then we will set the descriptor's
wMaxPacketSize as ep->ep.maxpacket.
I'm just wondering if you could share the wMaxPacketSize of your
platform (lsusb -v on HOST).
In my case it is:
wMaxPacketSize 0x0200 1x 512 bytes
on host: lsusb -v
[... snip ...]
Endpoint Descriptor:
bLength 7
bDescriptorType 5
bEndpointAddress 0x81 EP 1 IN
bmAttributes 2
Transfer Type Bulk
Synch Type None
Usage Type Data
wMaxPacketSize 0x0040 1x 64 bytes
bInterval 0
Endpoint Descriptor:
bLength 7
