Hi, I have an S32G-VNP-RDB2 but would consider myself a newbie. I can bring the system successfully to sleep mode via
echo mem > /sys/power/state
however I can't wake it up. Wake-on-LAN does not seem to be supported, I tried to send "Magic packet" with MAC address but no luck. The only way to revert this is via cold boot which I don't want. I checked the docs but could not really find anything obvious. Any simple/straightforward way to do this? Thanks!
Hi,
Which BSP version are you using?
It seems that this situation might have already been discussed under the following thread:
Wake On LAN for S32G2 RDB2 [Autolinux BSP v33] - NXP Community
Don't know if it is useful.
Please, let us know.
Hi, yeah, regarding BSP this is where it already starts - from boot log / dmesg I get
CPU: NXP S32G274A rev. 2.1.0
Linux version 5.10.41-rt42-05767-g120665743a9d
but BSP is never clearly mentioned.
I checked the link you added, read that and have the same behaviour, so this comes up during boot:
[ 1.035735] s32cc-dwmac 4033c000.ethernet: Wake-Up On Lan supported
So in theory it should work. But it doesn't. The board has six LAN ports, maybe this is only supported on one?
Hi,
Thanks for your feedback. The BSP version should be shown prior to the boot log or it is shown prior to the user being input on the console:
...
Also, as told under the thread, there is no NXP documentation about this specific implementation. There is though the GMAC Subsystem RM available under the S32G2 product page (link: S32G2 Safe and Secure Vehicle Network Processor | NXP Semiconductors) which shows the following [Page 100, GMAC Subsystem RM, Rev. 2, 03/2021]:
For which, the feature should be available.
Please, let us know.
