OK I got am437x-sk-evm suspend and resume working again and
LCD console comes back after resume. I also had to apply the
panel-simple fix "drm/panel-simple: fix connector type for
newhaven_nhd_43_480272ef_atxl" to get LCD working again.
I was missing /lib/firmware/am335x-pm-firmware.elf after updating
my NFSroot file system. And FYI, here are the modules I now load
with my test script:
modprobe omap-mailbox
modprobe omap_remoteproc
modprobe wkup_m3_rproc
modprobe wkup_m3_ipc
modprobe pm33xx
modprobe rtc-omap
modprobe pwm-omap-dmtimer
modprobe pwm-tiecap
modprobe pwm_bl
modprobe edt-ft5x06 # on am437x-sk-evm
modprobe pixcir_i2c_ts # NOT on am437x-sk-evm, only on am437x-gp-evm.dts
modprobe omapdrm
modprobe panel-simple
modprobe display-connector # starting with v5.7-rc1
modprobe omapdss
modprobe panel-dpi
modprobe omap-dss
And then I get the following with rtcwake -m mem -s 5.
Sometimes cps and NFSroot seems to take few tens of seconds to
recover though.
Regards,
Tony
