Hello,
I have a simmilar problem to https://community.nxp.com/t5/Layerscape/LS1046A-watchdog-timeout/m-p/1552553#M11398 but I do not find usefull the solution provided there.
I am trying to use the WD over uboot, just to check its functionality.When I activate the watchdog, It reset our board but the WDOGx_WRSR register does not change (its status is 0010h after WD reset). The commands that I use in uboot are:
mw.b 0x2A70000 0x4 1
mw.b 0x2A70001 0x34 1
## the board resets after the 2.5s
md.b 0x2A70004 2
## the output is 0010h
I have check with the HW departement and the RESET_REQ_B assertion properly handled.
Also, if I set [SRS] bit in WCR register, I could not see the [SFTW] bit in WRSR register as set.
Thank you very much.
