Hello,
DFU allows to transfer large files (such as initrd images) much faster than FEL.

Siarhei, can you give some pointers how to test those patches. I have A20-OLinuXino-Micro and Cubietruck and would be glad to give them a try.
Hello,
I tried to provide some basic usage instructions as a part of the commit message: https://patchwork.ozlabs.org/patch/535535/
Hi Siarhei, unfortunately I'm not able to compile even clean master with enabled CONFIG_USB_MUSB_GADGET. I'm using Linaro toolchain and get this error:
arm-linux-gnueabihf-ld.bfd: error: /home/pietrushnic/storage/wdc/projects/3mdeb/cubietruck/toolchains/gcc-linaro-4.9-2015.05-x86_64_arm-linux-gnueabihf/bin/../lib/gcc/arm-linux-gnueabihf/4.9.3/libgcc.a(_udivmoddi4.o) uses VFP register arguments, u-boot does not arm-linux-gnueabihf-ld.bfd: failed to merge target specific data of file /home/pietrushnic/storage/wdc/projects/3mdeb/cubietruck/toolchains/gcc-linaro-4.9-2015.05-x86_64_arm-linux-gnueabihf/bin/../lib/gcc/arm-linux-gnueabihf/4.9.3/libgcc.a(_udivmoddi4.o) Makefile:1183: recipe for target 'u-boot' failed make: *** [u-boot] Error 1
CONFIG_USB_MUSB_GADGET automatically enable CONFIG_USB_MUSB_SUNXI. When I try with CONFIG_USB_MUSB_SUNXI not set I'm getting other failure:
(...) drivers/usb/musb-new/musb_gadget.c:133:8: error: 'DMA_TO_DEVICE' undeclared (first use in this function) (...) drivers/usb/musb-new/musb_gadget.c:134:8: error: 'DMA_FROM_DEVICE' undeclared (first use in this function) : DMA_FROM_DEVICE); ^ (...) drivers/usb/musb-new/musb_gadget.c:164:7: error: 'DMA_TO_DEVICE' undeclared (first use in this function) ?

My steps: make CROSS_COMPILE=arm-linux-gnueabihf- Cubietruck_defconfig make CROSS_COMPILE=arm-linux-gnueabihf- menuconfig # enable CONFIG_USB_MUSB_GADGET make CROSS_COMPILE=arm-linux-gnueabihf- -j$(nproc)
Any idea how to narrow VFP problem ?
But you also need the "sunxi: cubietruck: Enable the USB OTG controller" patch from Maxime Ripard to enable USB OTG on the Cubietruck: https://patchwork.ozlabs.org/patch/530656/
Cannot apply this series to master cleanly. Should I try different tree ?
I think it would be interested to combine this method with Boris NAND support and get much better solution then {Live,Phoenix}Suit.
At this stage I'm only interested in the DFU usage as a speed booster for FEL. Booting over USB via FEL allows us to temporarily run more or less complete system (kernel and rootfs on ramdisk) on any Allwinner device without modifying existing pre-installed software on non-volatile storage. This already works fine, but we were not quite happy about the data transfer speed.
If you are interested in flashing NAND, then you can probably have a look at the recent fastboot patches from Maxime.
DFU means "Device Firmware Upgrade" and it can be also used for flashing NAND or writing images to SD cards over USB (if we hook up this part of the DFU functionality). The main question is how many alternative NAND flashing methods do we need?
IMHO one method that works would be great.
Best Regards,
