Sushmitha K

Part Number: AM62L

Dear Team,
We are working on AM62L SR1.1 with 11.01.16.13 sdk, when we enable wkup_uart0 in kernel dts board is not booing, hangs in kernel also we observe base baudrate of ttyS0 changing from 3M to 6M in boot log.
find the below prints where the board hangs
[    3.221602] printk: legacy console [ttyS0] disabled
[    3.227095] 2b300000.serial: ttyS0 at MMIO 0x2b300000 (irq = 159, base_baud = 6000000) is a 8250
[    3.236170] printk: legacy console [ttyS0] enabled
[    3.245860] printk: legacy bootconsole [ns16550a0] disabled

Dear Anshu Madwesh,

The below property has been already removed in the new SDK_11.01.16.13 version.
"assigned-clock-rates = <48000000>;"

Still we are facing issue when we enable the wakeup uart.
Kindly provide your inputs in this.

Regards,
Sushmitha
