I was able to get it working by adding "sudo" to the beginning of the line I use to launch the program.

So this seems to be a user permission issue, not an issue with the program. I have no folder called "50-myusb.devices" on my system (Linux Mint 19.2) so I tried the "sudo" thing. I'm not very well versed in Linux!

If someone is able to test version 2021-07-14_1617 on a P2 system, I would appreciate it.

Appears to work fine here as well. My version is also V. I turned on the 480MHz mode at the same time to test both.

Working fine here. My version is 'V'.
Can you explain what to look for. MCU? Is this the processor? What are the potential benefits?

Yes, (micro controller unit). The benefit may be more stable operation at 400 MHz for Y variant devices. It is working well here for P1 at 400 MHz, I don't have P2 available to test on.

Thanks for the quick reply. I will continue testing here on P2. Currently working fine at 480 for me as well. I will try 400, but not being the Y variant it may not be of help to you.

what does V mean, am i missing something
There are two versions of the MCU out there. Yesterday, I found that the last batch I was able to purchase in January is the Y variant. For those that don't know, it is nearly impossible to buy many MCU parts right now due to hoarding shortages. The Y and V variants both have exactly the same part number. The Y variant is only guaranteed to work up to 400 MHz.

Yes, it would help to know that P2 works fine at 400 MHz (even on the V variant).

I forgot to mention that you have to power-cycle the device after changing the 400/480 MHz setting for the change to take place. You can check the current operating frequency with the 'mcu_speed' command.

Reboot after reboot and saving of the advanced settings, my "V" version still shows that it is running at 400 MHz at the console. Any idea why it's not changing?

When you set/unset the option in the advanced tab, the command that is issued during <write config> is 'clk_480 0' or 'clk_480 1'. Example to switch to 480 manually using the console:
$ clk_480 1
$ save
$ system_reset
$ mcu_speed
Model P25RX Running @ 480 MHz
Does it work when you manually enter the commands?

Aah. System RESET. I saw you said "power cycle", and I just restarted the Btconfig software. @480MHz now. Thanks.
