Hello Poiana,
No, the imx6SX does not have power self test we have low power modes, for procedure for entering low power modes is described in
sect.19.5.3 Power modes i.MX6SX RM http://cache.freescale.com/files/32bit/doc/ref_manual/IMX6SXRM.pdf
AN4050 describes steps for “Dormant mode” or “Suspend" modes and System Idle mode.
Codes examples are described in attached Linux Manual Chapter 22 Low-level Power Management (PM) Driver.
Unfortunately "Low Power IDLE" is not implemented in linux, one will have to look at examples of
“Suspend" mode and System Idle mode and develop own procedure making combination of these
codes based on Table 10-1.
Regards
