Hi Shoval,


Can check in Uboot or Linux user space by accessing the address of the connected UART IP?

Example like "md" cmd in Uboot or "devmem" cmd in Linux pointing to the specific connected addresss of UART IP in your design. Should be able to observe some of the IP defaut reset values if the IP is presence in the working system.


Any failure indication in the booting logs when the system trying to probe the driver to the particular address of the UART IP?


Another thing is does the below enabled in the linux config file?

CONFIG_SERIAL_8250=y

CONFIG_SERIAL_8250_CONSOLE=y

CONFIG_SERIAL_OF_PLATFORM=y


Thanks.

Regards,
