- JC 01:30 PM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: Uart speed does not change when loading uboot. The variable "baudrate" has no effect.
- It is unusual for a design to change its debug UART's baud rate dynamically. The majority of our designs use the 115200 baud rate. If your design needs a different baud rate, I would rebuild u-boot and change CONFIG_BAUDRATE and change...

- Hi Dan
All clocks have been checked on a scope and are running at expected frequencies.
My HPS clock is 100MHz, and the two clocks I have tested as a PTP reference runs at 100MHz (first test) and 20MHz (second test).
When I run:

- The baudrate of the UART port when loading uboot does not depend on the value from the environment variable "baudrate" and is determined only by CONFIG_BAUDRATE. The rate can only be changed in the local session using the "setenv" comman...

- Hi Vidar,
As a quick test can you output the clock you are using to a pin and verify its frequency on a scope?

I changed to use netdev_info (instead of netdev_dbg) logging in stmmac_main.c and then I get:

- Hi Alex
In /var/log/boot there are no PTP debug messages.
Looking into stmmac_main.c, these PTP messages are printed from function stmmac_init_ptp using "netdev_dbg". I am not sure if these debug prints are enabled on my system?
I...

- Vidar,
If you look through your boot log do you see either of the following debug printouts?

- Hi
We have started implementing PTP on the MitySOM-5CSX board.
The first step is to get software timestamping to work, then hardware timestamping (since the Eth phy KSZ9031RNX does not seem to support PTP we are a bit unsure how well h...
