imx6Q fail to bring up CPU

jiujinhong · ‎08-30-2018

Hi, imx6Q board can't bring up another 2 CPU, can give some good advice?

Hi jiu

one can try with baremetal test using sdk (please check Chapter 3 Multicore Startup

iMX6_Firmware_Guide.pdf included in package), found on below link

SMP Enable in IMX6

or test with minimal linux image, try use the same image on i.MX6Q Sabre reference board.

May be useful to check number of cores in fuse NUM_CORES described in

Table 5-9. Fusemap Descriptions i.MX6Q Reference Manual

Hi Igor,

as u-boot print, the cpu is really iMX6Q, and Linux print 4 CPUs, we need FSL advice to fix this issue, please tell solution directly.

igorpadykov · ‎09-03-2018

Hi jiu

suggest to run nxp i.mx6q sabre sd reference board with demo images from link:

i.MX Software|NXP

check results, if results are good, replace processor from custom board to reference board

and check again.

Best regards
igor

jiujinhong · ‎09-03-2018

we dont have imx6q reference board, that means FSL can't give any good advice for us?

igorpadykov · ‎09-03-2018

I am afraid there is no way to give defnite answer without running some tests.

You can also try to change part to other, for example from other batch/date code.

jiujinhong · ‎09-03-2018

Hi Igor,

I have successfully built /home/jiujin/code/1.1.0_iMX6_Platform_SDK/output/mx6dq/sdk_unit_test/evb_rev_a/sdk_unit_test_ALL.bin, which cmd should use to run SMP test?

igorpadykov · ‎09-03-2018

please check Chapter 3 Multicore Startup iMX6_Firmware_Guide.pdf in doc folder

Best regards
igor

jiujinhong · ‎10-21-2018

Hi Igor,

I have provide multi-core test in below, please help to ask other people to answer if you can't give.

thanks a lot!

jiujinhong · ‎11-12-2018

issue is fixed due to Power.

jiujinhong · ‎10-17-2018

Hi Igor,

I have successfully boot multi-core test in my imx6Q, it run CPU0(Primary) and CPU1 only, can you give some further advice?
