I have a custom board that has a IMX6SL. The design is based on the IMX6SL-EVK design. My board has a PMIC and is running in LDO bypass mode. The watchdog reset seems to work perfect as long as I run the board at 1Ghz or 800 Mhz. When i manually set the CPU to 400Mhz (cpufreq-set -f 400000) and then try to issue a reset command from w/i linux the watchdog nolonger works. System hangs and I get "Watchdog reset failed to assert reset". Anyone else expierence this problem? Why does it work at 1Ghz & 800Mhz but not 400Mhz?
