Hi @huybk213, 480 kHz
is just a typo, it is fixed in this patch. Now the dmesg
will show 480 MHz
instead.
Note that 480 MHz
is only the internal clock used by the I2S hardware, not the REFCLK
output. The REFCLK
is always 12 MHz
.
Tks @redchenjs
Dear Redchenjs,
Thanks for your good code, i have a question about i2s clock. System only show clock of i2s ~ 480khz, how can i increase? Thank you
