However, an external LPO clock may be more reliable than using the internal, which is consequence of changing boardflags3. Just to make sure I understand the change: boardflags3 0x08101188 --> Wifi uses an external clock boardflags3 0x101188 ---> Wifi uses an internal clock Current dts does not output the 32kHz from MX7D to the Wifi chip, so I guess the below is correct. > So can the signal be measured with a scope to confirm it provides 32kHz? I am not sure if I can access this signal via scope. Thanks
