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.
