TWR-LS1021A-PB with CPU1 not online

[alessandromarin]

Hello,

I'm using a TWR-LS1021A-PB development board.

The kernel version is:

 root@ls1021atwr:/proc# uname -a
Linux ls1021atwr 3.12.37-rt51+ls1+gf488de6 #2 SMP PREEMPT RT Tue Jun 21 13:37:12 CEST 2016 armv7l GNU/Linux

The board comes up with core0 only working.

I see the following message for core1:

CPU1: failed to come online

Can anyone give me suggestions?

thank you

Please provide:

1) settings of all on-board switches

2) U-Boot log

Hello,

The switch configuration is as follows:

SW3[1:8] OFF,ON,ON,OFF,OFF,ON,OFF,ON

SW2[1:8] OFF,OFF,ON,OFF,OFF,ON,OFF,ON

Thank you

According to the U-Boot log the board has LS1021A Rev.1.0 and SDK v1.8 is the latest one supporting this silicon revision.

The SDK v1.9 and v2.0 support LS1021A Rev.2.0.

Do you see the same issue when precompiled image from SDK v1.8 is used and the board boots from NOR Flash?

[alessandromarin]

We have reconfigured the switches to boot from NOR Flash.

These are the messages from the board:

Now how we have to proceed to have Linux working?
