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... Jonathan Cormier

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: V J

RK 05:00 PM MityDSP-L138 (ARM9 Based Platforms) Software Development: Uart speed does not change when loading uboot. The variable "baudrate" has no effect.

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... Roman Kochkin

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

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