ETM of ARM Cortex M4

Lorenzo_UR over 6 years ago

i'm using Nucleo board F401RE.

i want to activate the ETM but not using a kit debugger.

i have to modify manually the value of some registers.

i downloaded two datasheet:

1) ETM Architecture specification
2) ETM technical reference manual

In the pdf number one i read that i have to unlock by writing a specific value : 0xC5ACCE55.

Which is the configurations of bits of the ETMCR ?

Thank you
