|  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?  |
