[U-Boot] bootloop with 2019-07 on Bananapi-r2

[Frank Wunderlich]

Hi,

i have an issue with 2019-07 (rc1 and rc4) on Bananapi-R2 (mt7623).

from the bootlog (seems like WDT triggers a reset):

U-Boot 2019.07-rc1-bpi-r2-00002-gb692d6e6b4 (Jun 23 2019 - 11:39:57 +0200)

CPU:   MediaTek MT7623 E3
DRAM:  2 GiB
WDT:   Started with servicing (60s timeout)

[USBD] USB PRB0 LineState: 0


the last line "[USBD]" is first line after reset (= first line after power on).

No issue on 2019-04 final, here i see no WDT-line:

U-Boot 2019.04-bpi-r2-00003-g0870aec1fb (Jun 23 2019 - 12:36:20 +0200)

CPU:   MediaTek MT7623 E3
DRAM:  2 GiB
MMC:   mmc at 11230000: 0, mmc at 11240000: 1
Loading Environment from MMC... Boot From SD(id:1)

*** Warning - bad CRC, using default environment

In:    serial
Out:   serial
Err:   serial
Net:

any idea how to get the cause? it is between 2019-04 final and 2019-07-rc1

https://github.com/frank-w/u-boot/tree/2019-04-bpi-r2 <<< affected
https://github.com/frank-w/u-boot/tree/2019-07-bpi-r2 <<< not affected (=rc1, but tested also rc4)
