usb_bulk_send() ERROR -4: No such device #155
Comments
I would guess it is a board problem or SPL configuration error. Loading the
SPL to SRAM works, but then it crashes after the DRAM have been configured
where it should load u-boot into DRAM.

… Hello,
I'm trying to boot new custom board with A64 via USB-OTG with this script
(sunxi-fel v1.4.2-110-g7a6a222 compiled from source). New board uses
LPDDR3, the previous board uses normal DDR3, so I'm using different SPL for
each board.
sunxi-fel -v $DEV \
spl $SPL \
write 0x44000 bl31.bin \
write 0x4a000000 u-boot.bin \
write 0x43100000 my.env \
write 0x4FC00000 boot.scr \
write 0x40080000 Image \
write 0x4FE00000 live-image.cpio.gz.bin \
write 0x4FA00000 sun50i-a64.dtb \
reset64 0x44000
The script works on the previous boark OK. On the new one I'm getting usb_bulk_send()
ERROR -4: No such device (it may have been disconnected) error.

Trying to boot from FEL
I'm not sure if it can be bug in sunxi-fel or electrical issue on the new
board (voltage drop). Do you have any advice?

What SPL are you using? Latest mainline U-Boot supports 64-bit SPLs for FEL booting now, so no extra SPL needed. |
