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

VJ 11:44 AM MitySOM-5CSX Altera Cyclone V Software Development: RE: LinuxPTP: 1PPS output is running at 0.1Hz

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

VJ 12:50 PM MitySOM-5CSX Altera Cyclone V Software Development: RE: LinuxPTP: 1PPS output is running at 0.1Hz

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... V J

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

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... V J

Hi,
Actually we disabled AutoRun.service (systemctl disable AutoRun.service) on board because we wanted to test further with new application generated files and we wanted to test it directly from MMC card. If we keep AutoRun.service en... Vivek Ponnani

Sounds like you might have a program error.
Note: If you want to verify if the file is the same one from your VM you can calculate an md5sum. And compare. Jonathan Cormier

From virtual machine, we always safely eject the card and then remove. What is running sync?
And once ... Vivek Ponnani

I don't see any problems with your procedure. Although you don't mention running @sync@ or safely unmounting your sd card. I know not doing this has been a problem for me in the past.
Unrelated: Remove comma so its just "rw noatime"... Jonathan Cormier
