Dear @aulia.widyaputra1,
What is the state of the board before you hit this issue? Is it used in office premises or lab? Also, could you run showvoltages on aurix console? Also, there is short time gap before thermal alert shows up on aurix console, we need to reset tegra and put it in recovery mode before thermal alert and check flashing manually using bootburn. could you check Reflash 99% , the sdkmange stucks - #18 by tonyb.zhao if it works for you?
