Bootloader transfer via debug uart fails in recovery mode


#1

For flashing bootloader I am referring the below link.
https://github.com/96boards/u-boot/blob/master/board/hisilicon/hikey/README

I am using Ubuntu 16.04 host machine and target board is Hikey.
Jumper setting are like: pin3-4 closed and all other pins of J15 is open.

I am getting below failure log while transferring l-loader.bin to /dev/tyyUSB0
[
$ sudo ./hisi-idt.py -d /dev/ttyUSB0 --img1=…/…/bin/l-loader.bin
±---------------------+
(’ Serial: ‘, ‘/dev/ttyUSB0’)
(’ Image1: ‘, ‘…/…/bin/l-loader.bin’)
(’ Image2: ', ‘’)
±---------------------+

(‘Sending’, ‘…/…/bin/l-loader.bin’, ‘…’)
failed
failed
.
.
the same continues till full file is transferred.
]

So now board is bricked and not able to flash bootloader.

Any help would be appreciated.

Hi @sreenad,

The link you mentioned is outdated. Please refer our documentation below for how to debrick/flash bootloader onto Hikey.

Thanks,
