13:23 topi`> back in business
13:24 topi`> it seems the new HB Pulse has a cortex-M4 embedded that could be used for interesting purposes like suspending until some external conditions are met (temperature? vibration?) - how can one control it from Linux userspace?
13:24 topi`> the holy grail would be to be able to run the board from a 12V battery
13:25 topi`> ...for weeks
13:56 jnettlet[m]> topi`: you use the rpmsg bus
13:57 jnettlet[m]> although currently the board power draw during suspend is still quite a lot. Especially if you have the HDMI firmware loaded.
13:57 jnettlet[m]> really the device you want is the iMX8X or iMX8M-mini...both are being designed for such applications
13:58 jnettlet[m]> we are putting lots of tiny socs and programmable radios for this purpose
14:05 topi`> for the rpmsg bus, is a mainline kernel OK or do you need the freescale kernel?
