ZCU106 Linux multicore (CPU 1~3) boot failed 2019.1


I am trying to using RPU to run bare-metal program.

And I am using Linux 2019.1 with remoteproc drvier version 2019.2 now.

(According to , 2019.1's drivers may have some bugs, so I just changed rpmsg/remoteproc drivers.)


But before I could test remoteproc, I found that CPU1~3 is failed on booting.


log is: 

[ 0.001542] smp: Bringing up secondary CPUs ...
[ 1.024585] CPU1: failed to come online
[ 1.024590] CPU1: failed in unknown state : 0x0
[ 2.049209] CPU2: failed to come online
[ 2.049214] CPU2: failed in unknown state : 0x0
[ 3.073833] CPU3: failed to come online
[ 3.073838] CPU3: failed in unknown state : 0x0
[ 3.073873] smp: Brought up 1 node, 1 CPU
[ 3.073878] SMP: Total of 1 processors activated.


And I think the rpmsg/remoteproc drivers is not related to the CPU 1~3 boot failed problem.


Any idea about this?

Here is my environment:

PL block design ONLY with PS module to do the simple test.

1. Using open source linux:

2. Build atf by:

3. Build pmufw by:

4. Build fsbl by:

5. Genrate devicetree by Xilinx SDK with DTG 2019.1.  Then add

&sdhci1 {

due to

6. bootargs add : (Without this, error message "mmc0: Timeout waiting for hardware interrupt" will occur, and booting will freeze)


(Another question:

When I tried to use Xilinx SDK to create fsbl/pmufw in IDE, boot.bin generated can not boot.

But if generate fsbl/pmufw like wiki link (in console), boot.bin can boot.)


PS: When I try to use remoteproc to run OpenAMP echo test on RPU0, system freezed after called start.

I have tested on zynq7000 with similar process, and everything goes fine.

# echo start > /sys/class/remoteproc/remoteproc0/state
[ 5863.770942] remoteproc remoteproc0: powering up r5@0
[ 5863.776596] remoteproc remoteproc0: Booting fw image rpmsg_test.elf, size 614448
