I want to turn off thermal shutdown.

Now our target board is shutdowned at 122 degree so I want to test at a higher temperature. (A72, R5F, C6x, C7x, GPU).

I'm testing with ti-thermal-test-suite on linux.

I'm refering to spracz5.pdf file.

I think that I just do command "devmem2 0x4205000c w 0x0"

Could you send me linux console command sequence?

Thank you.

That is the recommended Max temperature. I do not recommend testing at higher temperatures. What is the higher temperature
you are planning to test the silicon? Please do not turn of this feature. If it heats more then there might be risk of silicon damage!

The above should disable the global max temp alert generation.

If no other questions then please click on verify answer.
