Hello I don’t know how to calculate this “value”。And According to what document to change this value, change to what, what does this value represent?
I need help,Thanks
Hi sjz_shaohua,
The <value> is for the pinmux register, and you could find more details in the TRM document for your module.
You could also use the following command to read/write pinmux register as following.
Read:
$ sudo busybox devmem <address>
Write:
$ sudo busybox devmem <address> w <value>
OK,Thank you very much,I see
Another problem:
What do I do if I want to open a pin directly in a configuration file instead of through jetson-io.py, such as “aud_mclk”? Thanks
You could modify the pinmux dts directly.
Please share the full flash log for further check.
