    Hi Mahesh,

    The abort failure in sysc_probe() function typically is caused by kernel trying to enable a non-exist module.

    What is the exact part number of AM437x that you use? Please check the AM437x Datasheet Table 3-1 "Device Feature Comparison" to see what module doesn't exist, then disable the corresponding node in kernel devicetree. Pay attention to SGX and PRU-ICSS.
