Re: [U-Boot] Kernel hang when replace older uboot with uboot master V2

And I also added "root=" option to default env, it doesn't work either.

Hi all,      And When I turn off the log, its bootlog like this:

U-Boot 2019.01-00079-g3420a6fc6e-dirty (Feb 19 2019 - 17:19:16 +0800)

Qualcomm Atheros QCA9561 ver 1 rev 0 Model: AP152 Reference Board DRAM:  128 MiB Loading Environment from SPI Flash... SF: Detected w25q128bv with page size 256 Bytes, erase size 4 KiB, total 16 MiB, mapped at 9f000000 *** Warning - bad CRC, using default environment

Here is the culprit - the on-board (tuned, setup) envs are not accessible (or read in a wrong way).   Apparently the default envs doesn't have proper root=... setup.   Please check the env related entries in Kconfig.     Best regards
