Subject: [PATCH 0/3] usb: gadget: dfu: Fix timeout on erase when using big partition
Date: Tue, 24 Mar 2020 16:46:44 +0100 [thread overview]
Message-ID: <20200324154647.17341-1-jmaselbas@kalray.eu> (raw)
Hi,
The two first patch are focused on two fixes for an issue I encountered
when trying to use the DFU gadget on big flash partition (2MB).
You can find more information in each patch, but here is a short summary
of the issue:
When downloading a firmware into a big flash partition the erase
operation can take a long time to be complete from few seconds to
minutes in extreme cases. During the erase the DFU gadget does not
respond to any USB setup request, the host only see a stalled USB
endpoint and cannot get responses from DFU_GETSTATE nor DFU_GETSTATUS.
The last patch is a small fix that allow to use the dfu gadget after
being unbind, such as:
barebox:/ usbgadget -D /foo(foo)
barebox:/ usbgadget -d
barebox:/ usbgadget -D /bar(bar)
Best regards,
Jules
