Issue with running Linux on Cortex A7 and GOAL Sample Application on Cortex M3 simultaneously on RZ/N1D CPU Board + Expansion B

HI,

I am following"r01qs0022ed0005-rzn1d-quick-start-guide". I am stuck up at running Linux on Cortex A7 and GOAL Sample Application on Cortex M3 simultaneously on RZ/N1D CPU Board + Expansion B.

I am running Goal project Chase lights  "00410_goal\chase_lights" in ARM Cortex M3.

Linux kernel and dtb running in Flash for Cortex A7. I am able to ping with J22 and J23 after login with root and using ifconfig eth0 "IP0" up and ifconfig eth0 "IP1" up. Providing Flash linux device tree "uImage-rzn1d400-db-both-gmacs.dtb" with DFU utility in windows.

Once we provide => setenv bootcmd "sf probe && sf read 0x4000000 d0000 80000 && rzn1_start_cm3 && sleep 4 && sf read 0x8ffe0000 b0000 20000 && sf read 0x80008000 1d0000 600000 && bootm 0x80008000 - 0x8ffe0000"
=> saveenv

Reset the board – SW4. After the autoboot, only bin with A7 is running (Ping happens). But binary in Cortex M3 stops.

Please also clarify below  points also

1. How many ethernets can run individually with Cortex A7 and Cortex M3.

2. We need to run all 5 ethernets simultaneously, Please share if any application notes and projects available.

Hoping for a faster reply..

Thanks and regards,

Mohan
