FEL eMMC

[Perier]

Hi people,

I need your help, I have been struggling to make this method work (https://github.com/zador-blood-stained/fel-mass-storage or https://github.com/ThomasKaiser/sunxi-armbian-flasher-osx) on the A20 processor for several days, but nothing works, I use Einstein-A20 (https://mega.nz/#F!ZtwxCCJC!AIYHcTqz-ucjuzKnE9qD7A?5xZ3iT4J) and enter the FEL mode using the special button UBOOT_SELECT.

I made my own support for this board for uboot (_defconfig, .dts) and compiled u-boot-sunxi-with-spl.bin (Scroll down).
script.bin took from cubietruck.

That is, I use the h3 folder, only:
zImage, uInitrd, boot.scr

 

Сonnect the board in FEL mode to a virtual machine on VMvare Worstation 12.5.9. Ubuntu Bionic (armbian build system).

j @ ubuntu: ~ / fel-mass-storage $ sudo ./start.sh
[sudo] password for j:
Connect device in FEL mode and press <Enter>

After that, in Windows 10, a device appears with an error in getting the descriptor (USB\VID_0000&PID_0002\5&330350CB&0&5).

 

I have already reread all the topics on the forum related to uploading an image to eMMC, but as a rule, they are addressed to the H3 board.

The goal I’m following is to download a previously compiled armbian image to eMMc. With the preliminary partitioning of the file system using LUKS.

 

Perhaps there are some other ways to work with eMMC (without preloading and subsequent transfer from sd card)?
