Dear Lukasz Majewski,
Hi Marek,
Dear Lukasz Majewski,
This commit fixes problems with some non-standard requests send with device address instead of interface address (bmRequestType.Receipent field).
This happens with dfu-util (debian version: 0.5), which address non standard requests (like w_value=0x21 and bRequest=GET_DESCRIPTOR) to device. Without this fix, the above request is STALLED, and hence causes dfu-util to assume some standard configuration (packet size = 1024B instead of 4096B) In turn it displays following errors: Error obtaining DFU functional descriptor Warning: Assuming DFU version 1.0 Warning: Transfer size can not be detected ... Warning: Trying default transfer size 1024
This fix allows passing non-standard request to function setup code, where it shall be handled.
Tested at: Trats (exynos4210) Tested with:DFU and UMS gadgets
Can you please repost all the patches you want applied on u-boot-usb ? I'm completely lost in all this DFU stuff.
This is only one patch to replace patch done by Pantelis:
Patch to replace (revert): dfu: Send correct DFU response from composite_setup SHA1: fef31049fa06e516945114195eb14ac3549d0ad2
And this shall be replaced with posted patch.
Another patches (with UMS gadget support - done by Piotr Wilczek), also shall be added to u-boot-usb tree:
http://patchwork.ozlabs.org/patch/219744/ http://patchwork.ozlabs.org/patch/219746/ http://patchwork.ozlabs.org/patch/219745/
Ok, please check the u-boot-usb ... if it's OK, I will send Tom a pullrq (finally). Tom, do you still accept those for .04 ?
Best regards, Marek Vasut
