Hi,

My Tx2, host tools chain using Jetpack 3.3, rootfs using Jetpack 3.1(including apply_binaries.sh and nv_tegra/).

There is “mmc1: Timeout waiting for hardware interrupt.” in dmesg.

Hi Chun.liu,

I feel it is not good to use Jetpack3.3 + Jetpack3.1 rootfs.

As you know, all our QA is based on same rootfs+ kernel.

Any reason why you must use it? Also, could you try to verify this issue on Jeptack3.3 with full BSP?

Hi, WayneWWW

We had spent some time on rebuilding our rootfs based on Jetpack3.1 rootfs, don’t want to rebuild it.

But to support security feature, we need to use Jetpack 3.3 tools

The wifi works with full Jetpack 3.3(or 3.1) BSP.

Thanks!

Hi, WayneWWW

I fixed this issue.

coherent_pool=64M trigger this issue.
