    Hi,

    There are two possible software resets:

    • global cold reset
    • global warm reset

    Global cold reset is generally preferred as some control module registers are not cleared by warm reset.
    I am not sure what software you are using hence I am giving the register information.
    PRM_RSTCTRL(0x4AE0 7D00) register has field RST_GLOBAL_COLD_SW i.e. bit 1.
    You need to set it to trigger cold reset.

    Refer Table 3-31 of the TRM for device reset information.

    Hi Anubhav,

                      thanks for reply.

                      I am also facing issue to implement Watch Dog Timer in AM5729 processor with RTOS support. I followed Baremetal watchdog example code in my custom board. I checked JTAG debug mode, after 2 seconds it will reset. In debugger window i able to reset message. But  In SD card mode, after watch dog reset my program not start with main. i couldn't find where it failed. Kindly check and help us to resolve this issue.

    Regards,
